The American Society of Civil Engineers (ASCE) gave America's infrastructure a C- grade in its quadrennial assessment issued March 3. ASCE gave the nation's flood control infrastructure – dams and levees – a D grade. This is a highly concerning assessment, given that climate change is increasingly stressing dams and levees as increased evaporation from the oceans drives heavier precipitation events.
<h4>U.S. Dams Need $93.6 Billion in Upgrades</h4><p>The group's 2021 report card gave the nation's 91,000-plus dams a D grade, jus as they had received in each of its assessments since the first one was issued in 1998. Drawing upon the latest data from the Association of State Dam Safety Officials, ASCE estimated the cost of rehabilitating all U.S. dams at $93.6 billion, of which $27.6 billion is needed for federal dams. Over half (56.4%) of U.S. dams are privately owned. The cost to rehabilitate deficient high-hazard-potential dams, whose failure would result in loss of life, is estimated at nearly $20 billion. Over 2,300 dams in the U.S. are in this category. The average age of America's dams is 57 years.</p><p>The report identified one program that can help address existing funding needs – the High Hazard Potential Dam Rehabilitation Program authorized in the 2016 Water Infrastructure Improvements for the Nation Act. The goal of this program is to help fund the repair, removal, or rehabilitation of the nation's non-federal, high-hazard-potential dams. In federal fiscal year 2020, Congress appropriated $10 million for the program, less than 0.1% of the state dam safety group's needs estimate, and a quarter of the $40 million Congress had authorized for the program.</p>

<p>A 2019 <a href="https://apnews.com/article/f5f09a300d394900a1a88362238dbf77" target="_blank">story by the Associated Press</a> reported that the most recent U.S. fatalities from a dam failure were in March 2019, when the 92-year-old Spencer Dam on the Niobrara River in Nebraska failed, killing one person. The most recent previous dam failure fatalities involved seven people killed on Hawaii's Kauai Island in 2006 after the earthen wall of the Kaloko Reservoir collapsed.</p><p>At least five fatal dam failures occurred in the 1970s – Teton Dam, Idaho (14 deaths), Kelly Barnes, Georgia (39 deaths), Buffalo Creek coal slurry impoundment dam, West Virginia (125 deaths), Rapid City, South Dakota (238 deaths), and Johnstown, Pennsylvania (84 deaths). These failures ushered in the modern dam safety era. AP reported that many states have problematic private dams whose owners can't be identified. In 2018, for instance, Rhode Island listed 32 high- or significant-hazard dams with safety concerns and unknown owners.</p><p>A 2019 YaleEnvironment360 <a href="https://e360.yale.edu/features/in-an-era-of-extreme-weather-concerns-grow-over-dam-safety" target="_blank">story by Jacques Leslie</a> reported that "many people living on property that would be flooded if a dam fails are unaware of that possibility, in part because federal officials blocked public access to inundation maps after the September 11, 2001, terrorist attacks. In recent years, some states have again made the maps available. California requires that prospective buyers be informed if a property is in an inundation zone, a practice that should be far more widespread." The 2021 ASCE report card recommended initiating a public awareness campaign that would alert residents of the location and condition of dams in their area.</p>

<h4>U.S. Levees Need More Than $21 Billion in Upgrades</h4><p>In spring 2019, the midwest U.S. experienced severe flooding, causing over $20 billion in damage. More than 80 Corps of Engineers levee systems were overtopped or breached, sometimes multiple times, and more than 700 miles of levees were damaged. Levee repairs were estimated at $1 billion. However, the Army Corps estimated that the levees prevented almost $350 billion in flood damages from October 2018 to September 2019. At least 17 million people live or work behind a levee, and U.S. levees protect $2.3 trillion in property, so the condition of these levees is critical. In addition, approximately 1,400 sites listed in the federal Toxic Release Inventory – including many EPA Superfund sites – lie in areas at high risk of flooding, according to a 2018 <a href="https://www.nytimes.com/interactive/2018/02/06/climate/flood-toxic-chemicals.html" target="_blank" rel="noopener noreferrer">New York Times analysis</a>.</p><p>In that context, the Civil Engineers' 2021 report card grade of D for the nation's 40,000 miles of levees is concerning. Drawing upon the latest data from the Corps of Engineers, the ASCE says in its report card that $21 billion is needed to improve and maintain just the moderate to high-risk levees in the Corps of Engineers portfolio. That is about 15% of the known levees in the U.S.</p><p>U.S. levees are, on average, 50 years old, many built using engineering standards less rigorous than current best practices. Encouragingly, fewer than 4% of U.S. levees are rated high or very high risk, down from 5% in 2017. However, 80% of high- or very high-risk levees have issues that likely would result in a breach prior to overtopping in an extreme flood, the report said.</p><p>The report card identified one program that can help address existing funding needs – the National Levee Safety Program. In federal fiscal year (FY) 2021 this program was funded at $5 million, just 0.02% of the $21 billion needed, and just 6% of its FY21 $79 million authorization.</p>

<h4>Climate Change Is Driving More Precipitation and River Flood Damages</h4><p>Increased precipitation in the U.S. in recent decades, partially the result of climate change, has caused an additional $2.5 billion a year in U.S. flood damages, according to a <a href="https://www.pnas.org/content/118/4/e2017524118" target="_blank" rel="noopener noreferrer">January 2021 study</a> in the Proceedings of the National Academy of Sciences. The researches, climate scientists at Stanford University, found that between 1988 and 2017, heavier precipitation accounted for more than one-third of the $200 billion in damage. Causing heavier downpours, "Climate change may be exacerbating the cost of flooding," the authors concluded.</p><p>In an interview with E&E News, Study co-author Noel Diffenbaugh said in an interview with E&E News that "there is real economic value in avoiding higher levels of global warming. That's not a political statement. That's a factual statement about costs. And it also shows that there's real economic value to adaptation and resilience because we're clearly not adapted to the climate change that's already happened."</p><h4>U.S. River Floods Are Increasing in Frequency</h4><p>The number of "extreme streamflow" events observed in U.S. river systems since 1910 has increased significantly, according to a <a href="https://advances.sciencemag.org/content/6/49/eaba5939" target="_blank" rel="noopener noreferrer">December 2020 study</a> from Dartmouth College.</p><p>Along rivers that observed significant changes in streamflow in recent decades, the incidence of extreme streamflow events has doubled in frequency since the 1950-1969 period. Evan Dethier, a postdoctoral researcher at Dartmouth and lead author of the paper, said in <a href="https://phys.org/news/2021-01-river-droughts-canada.html" target="_blank" rel="noopener noreferrer">an interview with phys.org</a> that "the shifts toward more extreme events are especially important given the age of our dams, bridges, and roads. The changes to river flows that we found are important for those who manage or depend on this type of infrastructure."</p>

There's some good news amidst the grim global pandemic: At long last, the world's largest dam removal is finally happening.
<p>The <a href="https://www.latimes.com/opinion/story/2020-11-17/klamath-river-basin-dams-pacificorps-gavin-newsom-yurok-karuk-salmon-warren-buffett" rel="noopener noreferrer" target="_blank">landmark agreement</a>, which was finalized in November 2020 between farmers, tribes and dam owners, will finally bring down <a href="https://west.stanford.edu/news/blogs/and-the-west-blog/2020/winners-losers-and-landscape-might-emerge-if-klamath-river-dams-disappear" rel="noopener noreferrer" target="_blank">four aging, inefficient dams</a> along the Klamath River in the Pacific Northwest. This is an important step in restoring historic salmon runs, which have <a href="https://www.laprogressive.com/klamath-dam-removal/" rel="noopener noreferrer" target="_blank">drastically declined in recent years</a> since the dams were constructed. It's also an incredible win for the Karuk and Yurok tribes, who for untold generations have relied on the salmon runs for both sustenance and spiritual well-being.</p><p>The tribes, supported by environmental activists, led a decades-long effort to broker an agreement. They faced vehement opposition from some farmers and owners of lakeside properties, but in 2010, they managed what had seemed impossible: PacifiCorp, the operator of the dams, signed a dam removal agreement, along with 40 other signatories that included the tribes and the state governments of Oregon and California. Unfortunately, progress stalled for years when questions arose around who would pay for the dam removals.</p>

<p>The dam removal project is a sign of the decline of the hydropower industry, whose fortunes have fallen as the <a href="https://www.bbc.com/news/science-environment-46098118" target="_blank" rel="noopener noreferrer">troubling</a> cost-benefit ratio of dams has become clear over the years. The rise of more cost-effective and sustainable energy sources (including wind and solar) has hastened this shift. This is exactly the type of progress envisioned by the <a href="https://www.yumpu.com/en/document/read/17023836/dams-and-development-a-new-framework-for-decision" target="_blank" rel="noopener noreferrer">World Commission on Dams</a> (WCD), a global multi-stakeholder body that was established by the World Bank and International Union for Conservation of Nature in 1998 to investigate the effectiveness and performance of large dams around the world. The WCD released a damning landmark <a href="https://www.un.org/press/en/2000/20001117.dam.pressconferencepm.doc.html" target="_blank" rel="noopener noreferrer">report</a> in November 2000 on the enormous financial, environmental and human costs and the dismal performance of large dams. The commission spent <a href="https://www.un.org/press/en/2000/20001117.dam.pressconferencepm.doc.html" target="_blank" rel="noopener noreferrer">two years</a> analyzing the outcome of the trillions of dollars invested in dams, reviewing dozens of case studies and testimonies from over a thousand communities and individuals, before producing the report.</p><p>But despite this progress, we cannot take hydropower's decline as inevitable. As governments around the world plan for a post-pandemic recovery, hydropower companies sense an opportunity. The industry is eager to recast itself as climate-friendly (<a href="https://www.ecowatch.com/how-green-is-hydropower-1919539525.html" target="_self">it's not</a>) and <a href="https://www.hydropower.org/covid-19" target="_blank">secure</a> precious stimulus funds to revive its dying industry — at the expense of people, the environment and a truly just, green recovery.</p>Hydropower’s Troubling Record
<p>The world's largest hydropower dam removal project on the Klamath River is a significant win for tribal communities. But while the Yurok and Karuk tribes <a href="https://www.karuk.us/images/docs/press/bring_salmon_home.php" target="_blank">suffered</a> terribly from the decline of the Klamath's fisheries, they were by no means alone in that experience. The environmental catastrophe that occurred along the Klamath River has been replicated all over the world since the global boom in hydropower construction <a href="https://www.nationalgeographic.com/environment/article/hydropower" target="_blank">began</a> early in the 20th century.</p><p>The rush to dam rivers has had huge consequences. After decades of rampant construction, only <a href="https://www.nationalgeographic.com/environment/2019/05/worlds-free-flowing-rivers-mapped-hydropower/" target="_blank">37 percent of the world's rivers remain free-flowing</a>, according to <a href="https://www.nature.com/articles/s41586-019-1111-9" target="_blank" rel="noopener noreferrer">one study</a>. River fragmentation has <a href="https://academic.oup.com/bioscience/article/70/4/330/5732594" target="_blank" rel="noopener noreferrer">decimated freshwater habitats and fish stocks</a>, threatening food security for millions of the world's most vulnerable people, and hastening the <a href="https://www.forbes.com/sites/jeffopperman/2020/10/13/freshwater-wildlife-continues-to-decline-but-new-energy-trendlines-suggest-we-can-bend-that-curve/?sh=f9d175a61ee4" target="_blank" rel="noopener noreferrer">decline of other myriad freshwater species</a>, including mammals, birds and reptiles.</p><p>The communities that experienced the most harm from dams — whether in Asia, Latin America or Africa — often lacked political power and access. But that didn't stop grassroots movements from organizing and growing to fight for their rights and livelihoods. The people affected by dams began raising their voices, sharing their experiences and forging alliances across borders. By the 1990s, the public <a href="https://tinyurl.com/y55lnlst" target="_blank" rel="noopener noreferrer">outcry</a> against large dams had grown so loud that it finally led to the establishment of the WCD.</p><p>What the WCD found was stunning. While large dam projects had brought some economic benefits, they had also <a href="https://www.irn.org/wcd/" target="_blank" rel="noopener noreferrer">forcibly displaced an estimated 40 to 80 million people in the 20th century alone</a>. To put that number into perspective, it is more than the current population of present-day <a href="https://data.worldbank.org/indicator/SP.POP.TOTL?locations=FR" target="_blank" rel="noopener noreferrer">France</a> or the <a href="https://data.worldbank.org/indicator/SP.POP.TOTL?locations=GB" target="_blank" rel="noopener noreferrer">United Kingdom</a>. These people lost their lands and homes to dams, and often with no compensation.</p><p>Subsequent research has compounded that finding. A paper published in <a href="https://tinyurl.com/c7uznz" target="_blank" rel="noopener noreferrer">Water Alternatives</a> revealed that globally, more than <a href="https://tinyurl.com/yxw8x7ab" target="_blank" rel="noopener noreferrer">470 million people living downstream from large dams</a> have faced significant impacts to their lives and livelihoods — much of it due to disruptions in water supply, which in turn harm the complex web of life that depends on healthy, free-flowing rivers. The WCD's findings, released in 2000, <a href="https://www.irn.org/wcd/" target="_blank" rel="noopener noreferrer">identified</a> the importance of restoring rivers, compensating communities for their losses, and finding better energy alternatives to save rivers and ecosystems.</p>Facing a New Crisis
<p>Twenty years after the WCD uncovered a crisis along the world's rivers and recommended a new development path — one that advances community-driven development and protects freshwater resources — we find ourselves in the midst of another crisis. The global pandemic has hit us hard, with surging loss of life, unemployment and instability.</p><p>But as governments work to rebuild economies and create job opportunities in the coming years, we have a choice: Double down on the failed, outdated technologies that have harmed so many, or change course and use this transformative moment to rebuild our natural systems and uplift communities.</p><p>There are many reasons to fight for a green recovery. The climate is changing even <a href="https://www.nature.com/articles/d41586-018-07586-5" target="_blank" rel="noopener noreferrer">faster</a> than expected, and some dams — especially those with reservoirs in hot climates — <a href="https://tinyurl.com/w6w29t8" target="_blank" rel="noopener noreferrer">have been found to emit more greenhouse gases than a fossil fuel power plant</a>. Other estimates have put global reservoirs' human-made greenhouse gas emissions each year on par with <a href="https://www.climatecentral.org/news/greenhouse-gases-reservoirs-fuel-climate-change-20745" target="_blank" rel="noopener noreferrer">Canada's</a> total emissions.</p><p>Meanwhile, we now understand that healthy rivers and freshwater ecosystems play a <a href="https://www.environment.gov.au/system/files/resources/b55b1fe4-7d09-47af-96c4-6cbb5f106d4f/files/wetlands-role-carbon-cycle.pdf" target="_blank" rel="noopener noreferrer">critical role in regulating and storing carbon</a>. And at a time when <a href="https://www.un.org/sustainabledevelopment/blog/2019/05/nature-decline-unprecedented-report/" target="_blank" rel="noopener noreferrer">biodiversity loss is soaring</a>, anything we can do to <a href="https://academic.oup.com/bioscience/article/70/4/330/5732594" target="_blank" rel="noopener noreferrer">restore habitat is key</a>. But with <a href="https://www.researchgate.net/publication/271996520_A_Global_Boom_in_Hydropower_dam_Construction" target="_blank" rel="noopener noreferrer">more than 3,700 major dams proposed or under construction</a> in the world (primarily in the Global South, with over <a href="https://news.mongabay.com/2020/08/more-than-500-dams-planned-inside-protected-areas-study/" target="_blank" rel="noopener noreferrer">500 of these in protected areas</a>), according to a 2014 report — and the hydropower industry <a href="https://www.hydropower.org/covid-19" target="_blank" rel="noopener noreferrer">jockeying</a> for scarce stimulus dollars — we must act urgently.</p>Signs of Hope

<p>So what would a strong, resilient and equitable recovery look like in the 21st century? Let's consider one example in Southeast Asia.</p><p>Running through six countries, the Mekong River is the world's 12th-longest river, which is home to one of the world's most biodiverse regions, and includes the world's <a href="https://www.worldwildlife.org/places/greater-mekong#" target="_blank" rel="noopener noreferrer">largest</a> inland fishery. Around <a href="https://tinyurl.com/y6jrarjo" target="_blank" rel="noopener noreferrer">80 percent of the nearly 65 million people</a> who live in the Lower Mekong River Basin depend on the river for their livelihoods, according to the Mekong River Commission. In 1994, Thailand built the Pak Mun Dam on a Mekong tributary. <a href="https://tinyurl.com/y5ekfp4h" target="_blank" rel="noopener noreferrer">Six years later</a>, the <a href="https://tinyurl.com/yxcvs6up" target="_blank" rel="noopener noreferrer">WCD studied the dam's performance</a> and submitted its conclusions and recommendations as part of its final report in 2000. According to the WCD report, the Pak Mun Dam did not deliver the peaking energy service it was designed for, and it <a href="https://tinyurl.com/y38p3jaw" target="_blank" rel="noopener noreferrer">physically blocked a critical migration route</a> for a range of fish species that migrated annually to breeding grounds upstream in the Mun River Basin. Cut off from their customary habitat, fish stocks plummeted, and so did the livelihoods of the local people.</p><p>Neighboring Laos, instead of learning from this debacle, followed in Thailand's footsteps, <a href="https://tinyurl.com/y4eaxcq2" target="_blank" rel="noopener noreferrer">constructing two dams on the river's mainstem</a>, Xayaburi Dam, commissioned in 2019, and Don Sahong Dam, commissioned in 2020. But then a sign of hope appeared. In early 2020, just as the pandemic began to spread across the world, the <a href="https://www.theguardian.com/world/2020/mar/20/cambodia-scraps-plans-for-mekong-hydropower-dams" target="_blank" rel="noopener noreferrer">Cambodian government reconsidered its plans to build more dams on the Mekong</a>. The science was indisputable: A government-commissioned report showed that further dams would <a href="https://www.theguardian.com/environment/2018/may/16/leaked-report-warns-cambodias-biggest-dam-could-literally-kill-mekong-river" target="_blank" rel="noopener noreferrer">reduce the river's wild fisheries, threaten critically endangered Irrawaddy dolphins</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013WR014651" target="_blank" rel="noopener noreferrer">block nutrient-rich sediment from the delta's fertile agricultural lands</a>.</p><p><a href="https://data.opendevelopmentmekong.net/dataset/4f1bb5fd-a564-4d37-878b-c288af460143/resource/5f6fe360-7a68-480d-9ba4-12d7b8b805c9/download/volume-3_solar-alternative-to-sambor-dam.pdf" target="_blank" rel="noopener noreferrer">Studies</a> show that Cambodia didn't need to seek billions of dollars in loans to build more hydropower; instead, it could pursue more cost-effective solar and wind projects that would deliver needed electricity at a fraction of the cost — and <a href="https://www.worldwildlife.org/press-releases/wwf-statement-on-cambodian-government-s-decision-to-suspend-hydropower-dam-development-on-the-mekong-river" target="_blank">without the ecological disasters to fisheries and the verdant Mekong delta</a>.

<p>Increasingly, governments, civil servants and the public at large are rethinking how we produce energy and are seeking to preserve and restore precious freshwater resources.

Since December 2020, hundreds of groups and individuals from more than 80 countries have joined the <a href="https://www.rivers4recovery.org/" target="_blank" rel="noopener noreferrer">Rivers4Recovery</a> call for a better way forward for rivers and natural places. This paradigm will protect our rivers as critical lifelines — supporting fisheries, biodiversity, water supply, food production, Indigenous peoples and diverse populations around the world — rather than damming and polluting them.</p><p>The promise of the Klamath dam removals is one of restoration — a move that finally recognizes the immense value of free-flowing rivers and the key role they play in <a href="https://f.hubspotusercontent20.net/hubfs/4783129/LPR/PDFs/Living_Planet_Report_Freshwater_Deepdive.pdf" target="_blank" rel="noopener noreferrer">nourishing both the world's biodiversity and hundreds of millions of people</a>.

Looking for ways to cut down on single-use plastic while grocery shopping? You may already have eco-friendly shopping bags, but bringing your own reusable produce bags is another easy swap.
According to the UN Environment Program, up to 5 trillion single-use plastic bags are used globally each year, and because of the material they're made from, most municipal recycling centers don't accept them (more on this below).
The most sustainable option is to skip the bag altogether. You can also make your own reusable produce bags out of old T-shirts. But if you'd rather purchase them new, here are our recommendations for the best reusable produce bags on the market today.
<p><em>Each product featured here has been independently selected by the writer. If you make a purchase using the links included, we may earn commission.</em></p>
<h2>Why make the switch to reusable produce bags?<br/></h2><p>According to the <a href="https://www.unep.org/interactive/beat-plastic-pollution/" rel="noopener noreferrer" target="_blank">UN</a>, humans produce 300 million tons of plastic waste each year, and about 60% of the plastic produced since the early 1950s has ended up in a landfill or the natural environment.</p><p>Plastic grocery bags and produce bags are made from low-density polyethylene (LDPE). Technically, this type of <a href="https://www.ecowatch.com/plastic-recycling-myth-2647706452.html" target="_self">plastic can be recycled</a>. However, in practice, plastic bags easily clog recycling machinery, so <a href="https://millerrecycling.com/ldpe-out-of-landfills" rel="noopener noreferrer" target="_blank">most municipal recycling centers</a> do not accept this type of material.</p><p>A <a href="https://www.epa.gov/sites/production/files/2018-07/documents/smm_2015_tables_and_figures_07252018_fnl_508_0.pdf" rel="noopener noreferrer" target="_blank">study by the EPA</a> showed that only about 6% of the LDPE generated in 2015 was recycled. Other types of plastic, by comparison, were recycled at 18% and 10% rates.</p>Although some <a href="https://www.ecowatch.com/vancouvers-grocery-store-plastic-bags-2638807121.html" target="_self">grocery stores</a> offer plastic bag recycling, the easiest way to get around this is to refuse plastic bags in the first place. Many cities have instituted <a href="https://www.ecowatch.com/new-york-plastic-bag-ban-begins-2645319695.html" target="_self">plastic bag bans</a>, but more often than not, it's up to individuals to choose to make the switch to reusable grocery bags in their day-to-day lives.<p><br/></p><p><em><em><strong><a href="https://www.ecowatch.com/about-ecowatch-2641507575.html?rebelltitem=47#rebelltitem47" target="_self">Melissa Smith</a> </strong>is an avid writer, scuba diver, backpacker, and all-around outdoor enthusiast.

The numbers of migratory freshwater fish such as salmon have declined 76 percent since 1970. Mike Bons / 500px / Getty Images
The latest warning of the Earth's mounting extinction crisis is coming from its lakes and rivers.
<p>A new <a href="https://wwfint.awsassets.panda.org/downloads/world_s_forgotten_fishes__report_final__1.pdf" target="_blank">report</a> from a coalition of 16 <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> groups warns that almost a third of freshwater <a href="https://www.ecowatch.com/tag/fish" target="_self">fish</a> species face extinction because of human activity.</p><p>"Nowhere is the world's nature crisis more acute than in our rivers, lakes and wetlands, and the clearest indicator of the damage we are doing is the rapid decline in freshwater fish populations. They are the aquatic version of the canary in the coal mine, and we must heed the warning," Stuart Orr, WWF global freshwater lead, said in a <a href="https://wwf.panda.org/wwf_news/press_releases/?1529966/Worlds-forgotten-fishes-vital-for-hundreds-of-millions-of-people-but-one-third-face-extinction-warns-new-report" target="_blank">statement</a> Tuesday announcing the report.</p><p>WWF is one of the many organizations behind the report, along with the Alliance for Freshwater Life, Conservation International and The Nature Conservancy, to name a few. Together, the groups emphasized the incredible diversity of the world's freshwater fish and their importance for human wellbeing.</p><p>There are a total of 18,075 freshwater fish species in the world, accounting for 51 percent of all fish species and 25 percent of all vertebrates. They are an important food source for 200 million people and provide work for 60 million. But their numbers are in decline. The IUCN Red List of Threatened Species has declared 80 to be extinct, 16 of those in 2020 alone. The numbers of migratory freshwater fish such as salmon have declined 76 percent since 1970, while mega-fish such as beluga sturgeon have fallen by 94 percent in the same time period. In fact, freshwater <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> is plummeting at twice the rate of biodiversity in the oceans and forests.</p>
<p>Despite this, freshwater fish get much less attention than their saltwater counterparts, the report authors say. Titled "The World's Forgotten Fishes," it argues that policy makers rarely consider river <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> when making decisions. </p><p>The main threats to freshwater fish include building <a href="https://www.ecowatch.com/tag/dams" target="_self">dams</a>, syphoning river water for irrigation, releasing wastewater and draining wetlands. Other factors include <a href="https://www.ecowatch.com/tag/overfishing" target="_self">overfishing</a>, introducing <a href="https://www.ecowatch.com/tag/invasive-species" target="_self">invasive species</a> and the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>.</p><p>"As we look to adapt to climate change and we start to think about all the discussions that governments are going to have on biodiversity, it's really a time for us to shine a light back on freshwater," Orr told <a href="https://www.nbcnews.com/news/world/extinction-threatens-third-freshwater-fish-species-report-finds-n1258591" target="_blank">NBC News</a>.</p><p>To protect these forgotten fishes, the report authors outlined a six-point plan:</p><blockquote>1. Let rivers flow more naturally;<br>2. Improve water quality in freshwater ecosystems;<br>3. Protect and restore critical habitats;<br>4. End overfishing and unsustainable sand mining in rivers and lakes;<br>5. Prevent and control invasions by non-native species; and<br>6. Protect free-flowing rivers and remove obsolete dams.</blockquote><p>They also called on world leaders to include freshwater ecosystems in an ambitious biodiversity agreement at the upcoming UN Convention on Biological Diversity conference in Kunming, China.</p><p>But the solution will require more than just government action.</p><p>"It's now more urgent than ever that we find the collective political will and effective collaboration with private sector, governments, NGOs and communities, to implement nature-based solutions that protect freshwater species, while also ensuring human needs are met," Carmen Revenga of The Nature Conservancy told <a href="https://www.bbc.com/news/science-environment-56160756" rel="noopener noreferrer" target="_blank">BBC News</a>.</p>

State Disaster Response Fund personnel prepare for deployment in Uttarakhand state on February 7, 2021 after a glacier broke off in the Himalayas, causing flash floods along the Dhauli Ganga river. -/ AFP / Getty Images
A piece of Himalayan glacier in the Indian state of Uttarakhand broke off and fell into a river Sunday, triggering an avalanche and floods that have killed at least 20 people so far, while nearly 200 remain missing.
<p>The incident comes as Himalayan glaciers are melting twice as fast as they were in 2000 largely because of the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>, <a href="https://www.ecowatch.com/himalayan-glacier-melt-doubled-2638927563.html" target="_self">according to a study published in 2019</a>.</p><p>"This looks very much like a climate change event as the glaciers are melting due to global warming," Dr. Anjal Prakash, a lead researcher with the United Nation's Intergovernmental Panel on Climate Change (IPCC), told <a href="https://www.cbsnews.com/news/glacier-in-india-burst-dam-flood-uttarakhand-latest-news/" target="_blank">CBS News</a>.</p><p>The collapse occurred after 10 p.m. local time when a piece of the Nanda Devi glacier broke off, sending flood waters cascading down the Dhauli Ganga river valley, <a href="https://www.cnn.com/2021/02/08/asia/india-glacier-dam-disaster-climate-intl-hnk/index.html" rel="noopener noreferrer" target="_blank">CNN reported</a>. The flood destroyed the Rishiganga Power project, a small 13.2-megawatt <a href="https://www.ecowatch.com/tag/dams" target="_self">dam</a>, and severely damaged a 520-megawatt dam under construction, trapping workers in tunnels. The flooding also forced villagers to evacuate downstream.</p><p>"It came very fast, there was no time to alert anyone," Sanjay Singh Rana, who lives in the riverside Raini village, told <a href="https://www.reuters.com/article/us-india-disaster-idUSKBN2A706O" rel="noopener noreferrer" target="_blank">Reuters</a>. "I felt that even we would be swept away."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="b3d68011e19c0d9410deb98e8059557d"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/-6ppIUXlwLQ?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>Most of the dead and missing worked at the two hydroelectric projects. About 21 people are missing from the Rishiganga dam, and another 150 people are missing from the larger project, according to CBS News. Workers are trapped inside two tunnels at the latter, CNN reported. Rescuers freed 12 people from the smaller tunnel on Sunday, but are still trying to extricate 35 people believed to be trapped inside the larger tunnel.</p><p>"Some people inside the tunnel are probably alive or half alive, we are trying to rescue them," Ashok Kumar, Uttarakhand state's director general of police told CBS News.</p><p>Rescue workers were able to clear the mouth of the tunnel on Monday, according to CNN.</p>
<div id="88b2a" class="rm-shortcode" data-rm-shortcode-id="1cd85c3d9f12c5311b240204389f2ade"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1358410793633521665" data-partner="rebelmouse"><div style="margin:1em 0">Every life matters, every hand helps!

<p>Meanwhile, 20 bodies have been recovered from the region, Kumar told CNN. The flooding also knocked over trees and buildings and cut off around 2,500 people in 13 villages. However, rescue workers had reached all of the impacted villages by Monday afternoon, Kumar told CNN. Authorities also said on Monday that the threat of new flooding had ended, according to CBS.</p><p>The incident raises questions about developing a region that is vulnerable to climate change. The IPPC's Special Report on Oceans and Cryosphere warned that glacier retreat could increase the risk of landslides, floods and cascading events in regions where these disasters were previously unheard of, the <a href="https://timesofindia.indiatimes.com/india/climate-change-behind-uttarakhand-glacier-burst-experts-feel/articleshow/80736594.cms" target="_blank">Times of India reported</a>.</p><p>Despite this, there has been a push to build more dams in the region, which environmentalists in India have warned against.</p><p>"This disaster again calls for a serious scrutiny of the hydropower dams building spree in this eco-sensitive region," Ranjan Panda, a Combat Climate Change Network volunteer, told Reuters. "The government should no longer ignore warnings from experts and stop building hydropower projects and extensive highway networks in this fragile ecosystem."</p>
<p>At the same time, IPCC's Prakash called for more efforts to monitor climate change impacts in the region.</p><p>"[T]his event actually shows how vulnerable we could be," he told the Times of India.</p><p>The disaster comes about eight years after the "Himalayan tsunami" of 2013, when heavy monsoon rains triggered floods and landslides that killed nearly 6,000 people in Uttarakhand, Reuters reported. However, Sunday's incident did not occur during the rainy season, and the weather report for the region showed no record of rain or snow, Dr. Mohd Farooq Azam, assistant professor of glaciology and hydrology at IIT Indore, told the Times of India.</p><p>"There is no doubt that global warming has resulted in the warming of the region," Azam said.</p>

There are more than 90,000 dams in the United States. Many of those dams are at risk of failure.
<iframe style="border: none" src="//html5-player.libsyn.com/embed/episode/id/17277566/height/45/theme/standard/thumbnail/yes/direction/backward/" height="45" width="100%" scrolling="no" allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen></iframe>
<p>"Most of them were built more than 50 years ago. Usually, the design life of a dam is between 50 and 60 years, so a lot of our dams are already past their design age," says Paulina Concha Larrauri, a researcher at Columbia University.</p><p>She says many of these dams are not only old, but poorly maintained.</p><p>"There's a lot of variation on the safety and oversight of these dams across the country," she says.</p><p>In many areas, climate change is making the situation even more dangerous by causing more frequent and heavier rains.</p>
<p>In a <a target="_blank" href="https://www.essoar.org/doi/abs/10.1002/essoar.10503795.1">recent report</a>, Concha Larrauri and her team analyzed the risks and potential impacts of dam failures. She says that if one dam fails, it can cause other breaches downstream.</p><p>The risks can be extensive, and not just to people and homes. Flood waters can disrupt power generation and block roads and railways.</p><p>But funds to address the problem are limited, so she says it's important to assess the risks and potential losses, and prioritize repairs accordingly.</p>

Largest Dam Removal Project in U.S. History Restarts With Interstate Partnership

In a historic move to resurrect the largest dam removal project in the U.S., Oregon, California, the Yurok Tribe and the Karuk Tribe signed an agreement on Tuesday to push forward on dam removal.
<p>The two states take on the liability of the project, along with the Klamath River Renewal Corporation, the nonprofit in charge of the demolition, after the project stalled in July.</p><p>The dam removal project is essential to the tribes in the region — the Klamath River on the Oregon-California border — and will reopen hundreds of miles of river access to salmon that have been blocked for more than a century, in what is seen as one of the largest salmon restoration attempts in U.S. history. The removal would drain large reservoirs and reshape California's second-largest river.</p>
<p>The dams are not a part of the irrigation infrastructure in the region and are used only for power generation.</p><p>If U.S. regulators approve the plan, the project will remove four hydroelectric dams on the lower Klamath River. Legal challenges have stymied the plans from coming to fruition, as environmentalists and tribes had hoped demolition would start by 2022.</p><p>"The Klamath River is a centerpiece of tribal community, culture and sustenance and a national ecological treasure," California governor Gavin Newsom said in a <a href="https://www.gov.ca.gov/2020/11/17/governor-newsom-oregon-governor-brown-tribal-leaders-and-klamath-dam-owner-announce-agreement-to-advance-historic-salmon-restoration-plan/?utm_source=California+Trout+List&utm_campaign=5380e844e9-EMAIL_CAMPAIGN_Trout_Clout_Klamath_MOU&utm_medium=email&utm_term=0_cf2a51cf18-5380e844e9-232605593&mc_cid=5380e844e9&mc_eid=eeeff31369" target="_blank">statement</a> about the partnership. "With this agreement, we are closer than ever to restoring access to 400 miles of salmon habitat which will be a boon to the local economy."</p><p>In July, the project <a href="https://apnews.com/article/123f20f9e4b8948cf7d948482a8eec1d" target="_blank" rel="noopener noreferrer">was stalled</a> due to questions by Federal Energy Regulatory Commission concerning cost overruns and accidents, and if the Klamath River Renewal Corporation was in a fecund position to handle any upcoming issues.</p><p>However, the new state partnership adds an influx of $45 million to the project's $450 budget. The $45 million will be paid between Oregon, California, and the utility PacifiCorp as a contingency fund. PacifiCorp operates the dams and is owned by Berkshire Hathaway, one of billionaire Warren Buffett's companies.</p>
<p>Back in July the FERC found it necessary to keep PacifiCorp on the project as a co-licensee, although PacifiCorp was always in line to be removed from the deal, as it promised public utility commissions in Oregon and California, to better serve its ratepayers. If left on the deal as a co-licensee, by federal law PacifiCorp could end up paying itself to install fish ladders — concrete chutes in structures that fish pass through — to help the salmon migrate to spawning waters upstream.</p><p>In the new agreement, if approved by regulators, PacifiCorp would be removed as a co-licensee.</p><p>"As Yurok tribal people, it is our sacred duty to bring balance to the Klamath River," Yurok Tribe Chair Joseph James said in a <a href="http://www.klamathrenewal.org/bi-state-agreement-with-klamath-dam-owner-advances-historic-salmon-restoration-plan/?fbclid=IwAR0PixUu9UBM18PIx3FpPZOZJSo6XFNF2EZfydf1mTN7-k-j2AAO70XAN4A" target="_blank">KRRC statement</a>.</p><p>"At its heart, dam removal is about healing and restoration for the river, for the salmon, and for our people. We have never wavered from this obligation and we are pleased to see dam removal come closer to reality through this agreement. Reaching this important milestone would not be possible without the many tribal people who have dedicated their lives to restoring the river."</p>

By Tara Lohan
In 1999 a cheering crowd watched as a backhoe breached a hydroelectric dam on Maine's Kennebec River. The effort to help restore native fish populations and the river's health was hailed as a success and ignited a nationwide movement that spurred 1,200 dam removals in two decades.
<p>The era of building large dams in the United States, which defined so much of the 20th century, is over. The prime spots for development were cemented decades ago, and the ensuing harm to fish and other wildlife has been well documented. Attention is <a href="https://www.nytimes.com/2020/10/13/climate/environmentalists-hydropower-dams.html" target="_blank">now focused</a> on removing obsolete dams and retrofitting existing hydroelectric dams to reduce ecological harm and increase energy efficiency.</p><p>Many other countries are in the same boat. Across Europe and North America "big dams stopped being built in developed nations because the best sites for dams were already developed, and environmental and social concerns made the costs unacceptable," found a <a href="https://www.pnas.org/content/115/47/11891" target="_blank">2018 study</a> in the <em>Proceedings of the National Academy of Sciences</em>.</p>
<p>Canada appears to be the exception to that.</p><p>Large dams are still being built across Canada, from Muskrat Falls in Labrador to the generically titled "Site C" in British Columbia, despite <a href="https://www.spglobal.com/marketintelligence/en/news-insights/latest-news-headlines/inquiry-slams-nalcor-s-c-12-7b-muskrat-falls-hydro-project-as-misguided-57533638" target="_blank">cost overruns</a>, outcry from some <a href="https://thenarwhal.ca/i-dont-see-why-anything-should-be-secret-first-nation-rejected-28-million-in-site-c-dam-deal-court-docs-reveal/" target="_blank" rel="noopener noreferrer">First Nations</a> and even <a href="https://thetyee.ca/News/2017/03/13/UN-Calls-for-Site-C-Review/" target="_blank" rel="noopener noreferrer">environmental concerns</a> from the United Nations.</p><p>Hydroelectric power already supplies 60% of the country's energy. But the dam building isn't just to feed Canada's power needs. It's also become a hot export commodity.</p><p>As U.S. states look to meet new clean energy targets, imported low-carbon hydropower from across the northern border has become a larger part of the conversation — and the grid. New England already gets 17% of its energy from Canadian hydropower, Midwest states around 12% and New York 5%.</p><p>That number is likely to jump.</p><p>A new transmission project to bring 250 megawatts of Canadian hydropower to the United States <a href="https://renewablesnow.com/news/minnesota-power-brings-online-250-mw-hydro-wind-transmission-line-702303/" target="_blank" rel="noopener noreferrer">just came online in Minnesota</a>. Two more are in the works for Massachusetts and New York.</p>
<p>Proponents say we need large-scale hydro to grease the wheels of the clean energy transition. Others caution that it comes with a larger environmental cost compared to wind and solar and could open the floodgates for more dam building.</p><p>There's one shared bit of common ground, though: We need to act quickly and wisely to tackle the climate crisis.</p><p>"This is the decade for getting 50% of the way there on renewables, but also proving out the pathway to get to net-zero by mid-century, if not before," says Peter Rothstein, president of the <a href="https://www.necec.org/" target="_blank">Northeast Clean Energy Council</a>.</p><p>How hydro figures into that process is still a complicated issue.</p>
<h3>Clean Energy Demand Surges</h3><p>The Northeast is one place where the energy transition is off and running.</p><p>All six New England states have pledged to cut greenhouse gas emissions 80% over 1990 levels by 2050, and some are aiming higher.</p><p>Neighboring New York is also keeping pace. Last year the Empire State committed to achieving an 85% reduction in greenhouse gas emissions by 2050 and 70% renewable electricity by 2030.</p><p>How will those goals be achieved?</p><p>For some, imported Canadian hydropower looks poised to play a big role, and two new projects appear close to breaking ground.</p>

<p><a href="https://chpexpress.com/" target="_blank" rel="noopener noreferrer">Champlain Hudson Power Express</a>, a 330-mile-long transmission line, would deliver 1,000 megawatts of hydropower from Quebec to the New York metro area and could supply about a million homes — helping to reduce dependence on fossil fuels.</p><p>The project — a joint venture of the province-run Hydro-Québec and Transmission Developers Inc., a subsidiary of the private equity firm Blackstone Group — has already received the necessary permits for construction, but no contracts for the power have been signed.</p><p>Construction, however, could still start next year, with the project scheduled to come online in 2025.</p><p>Massachusetts has an even bigger project in the works. <a href="https://www.necleanenergyconnect.org/project-overview" target="_blank">New England Clean Energy Connect</a> would bring 1,500 megawatts of capacity through a 145-mile-long transmission line running through Maine from Canada to Massachusetts. It too would come from Hydro-Québec, this time working in conjunction with Central Maine Power.</p><p>The project, which is projected to cut greenhouse gas emissions by 3 million tons a year in New England, has received its necessary permits from the state of Maine but still awaits federal permits from the Department of Energy and the Army Corps of Engineers.</p><p>Opposition groups, including some environmental organizations, are also <a href="https://www.nrcm.org/programs/climate/proposed-cmp-transmission-line-bad-deal-maine/" target="_blank" rel="noopener noreferrer">challenging various aspects of the project</a> in court. And a coalition of First Nations communities that have seen dams built on their ancestral lands have voiced their opposition. (You can read more about that transmission line in <a href="https://therevelator.org/hydropower-necec/" target="_blank" rel="noopener noreferrer">Part I of this series</a>.)</p><p>More could be on the way. Nalcor Energy — the province-run hydro company of Newfoundland and Labrador — is nearing completion on its 824-megawatt <a href="https://muskratfalls.nalcorenergy.com/" target="_blank" rel="noopener noreferrer">Muskrat Falls hydro project</a> on the Churchill (or Grand) River. Costs have just <a href="https://www.thechronicleherald.ca/business/regional-business/muskrat-falls-costs-top-131-billion-503057/" target="_blank" rel="noopener noreferrer">surpassed $13 billion</a> — twice what was first estimated.</p><p>Some of the energy is already slated to be sent to other parts of Canada and then — hopefully, <a href="https://muskratfalls.nalcorenergy.com/project-overview/" target="_blank" rel="noopener noreferrer">according to Nalcor</a> — to New England.</p>
<h3>Environmental Considerations</h3><p>What's the net impact of these planned projects? That's hard to say. Tallying the environmental benefit or harm from large-scale hydro is complicated.</p><p>One of the biggest metrics of assessing environmental impact is greenhouse gas emissions.</p><p>The first phase of emissions comes just from building its infrastructure. Large-scale hydropower involves the construction of generating stations, and often accompanying dams and reservoirs. And then there are hundreds of miles of transmission lines that need to be constructed to move that power.</p><p>What comes next, once a project comes online, depends on multiple factors. Research has shown that hydropower emissions vary widely based on the location, climate and area of land flooded. Hydro emissions are also highest when a reservoir is first flooded and then decrease in the following years.</p><p>All told, over the life cycle of a project, most hydropower is cleaner than fossil fuels, although not always as clean as wind and solar. A <a href="https://www.nature.com/articles/s41560-017-0032-9" target="_blank" rel="noopener noreferrer">study</a> in <em>Nature Energy</em> on the projected life-cycle emissions of energy sources put solar at 6 grams of CO2 equivalent per kilowatt hour and wind at 4. The researchers estimated typical hydro at 97, but there's great variation between sites.</p><p>A 2014 <a href="https://www.hydroquebec.com/data/developpement-durable/pdf/comparing-power-generation-options-and-electricity-mixes.pdf" target="_blank" rel="noopener noreferrer">report</a> prepared by the research group CIRAIG on behalf of Hydro-Québec found the average life-cycle emissions of the company's fleet of 62 generation stations was between 6 and 17 grams of CO2 equivalent per kilowatt hour.</p><p>Alain Tremblay, Hydro-Québec's lead scientist on greenhouse gas emissions, says tracking from their most recent complex of dams on the Romaine River shows emissions between 5 and 10 grams of CO2 equivalent per kilowatt hour.</p>
<p>There are other environmental considerations beyond greenhouse gas emissions.</p><p>The nonprofit Natural Resources Council of Maine opposes the New England Clean Energy Connect, in part out of concern about fragmented habitat and critical wildlife populations, including brook trout. The transmission line would require clearing a 53-mile stretch of forest through the North Maine Woods.</p><p>In New York the nonprofit <a href="https://www.riverkeeper.org/" target="_blank">Riverkeeper</a> reversed its earlier support for the Champlain Hudson Power Express and has now <a href="https://www.riverkeeper.org/news-events/news/energy/riverkeeper-statement-regarding-the-champlain-hudson-power-express/" target="_blank" rel="noopener noreferrer">come out against that project</a>, which would send its electrical cable down the length of the Hudson River.</p><p>"This sets a precedent that the Hudson is a conduit for extension cords from Canada or from anywhere," says John Lipscomb, Riverkeeper's vice president of advocacy. "It should be off limits to that kind of thing."</p><p>The Hudson contains legacy pollution from polychlorinated biphenyls (PCBs) dumped decades ago and other contaminants that could be turned up as the cable is dug in the riverbed. Over the years some of that pollution has been remediated, but not all. And plans to avoid putting cable in the areas of the worst-known contamination aren't sufficient to protect the ecosystem, he says.</p>

Atlantic sturgeon were brought to the brink of extension in the 20th century and are now are listed as an endangered species. NOAA
<p>There's also concern that imperiled fish species, like endangered shortnose sturgeon and Atlantic sturgeon, could be harmed by the electrical cable. The river was designated as critical habitat for Atlantic sturgeon, but no <a href="https://biologicaldiversity.org/w/news/press-releases/regulators-warned-of-champlain-hudson-power-express-projects-environmental-impact-2020-10-08/" target="_blank">Endangered Species Act review</a> has been initiated to assess if the cable could threaten fish populations.</p><p>"Both of these fishes have nervous systems similar to that of sharks, which are incredibly sensitive to electric signals," says Roger Downs, conservation director of the Sierra Club Atlantic Chapter. "It's a huge experiment to suddenly put an electrical signal down the backbone of this river."</p><p>Lipscomb shares this concern. After all the work that's been done in recent years to help restore the Hudson and its estuary, he says "it's heartbreaking that we still think of this river as a resource."</p><p>Hydropower may be renewable, he says, but from an environmental perspective it isn't sustainable. "Unless a river's value is zero," he says. "If a river has any value as an ecosystem, as a host for life, then hydropower isn't even a consideration."</p>
<h3>Upstream Justice Concerns</h3><p>In 1990 a group of Cree and Inuit protestors paddled the Hudson River to Manhattan to ask New Yorkers to <a href="https://www.cbc.ca/radio/asithappens/as-it-happens-wednesday-edition-1.3044034/commemorating-25th-anniversary-of-historic-odeyak-voyage-1.3044498" target="_blank" rel="noopener noreferrer">oppose a power purchase</a> agreement between the state and Quebec and the construction of a second dam in the James Bay hydroelectric project in northern Quebec.</p><p>They were successful. Now, 30 years later, a different group of First Nations is making a similar plea.</p><p>On October 7 the First Nations of Pessamit, Wemotaci, Pikogan, Lac Simon and Kitcisakik sent a letter to the U.S. Department of Energy stating their opposition to the Massachusetts transmission line. The groups wrote that one-third of Hydro-Québec's installed power is "produced in our respective ancestral territories from reservoirs, dams, power plants and various other installations, without prior consultation, without our consent and without compensation."</p><p>Over the decades of hydropower buildout in Canada many First Nations communities — but not all — have been consulted on projects and struck agreements with power companies.</p><p>Major hydroelectric projects have altered the flow of rivers and in some cases, the food and cultural resources used by Indigenous communities.</p><p>There are also health concerns.</p><p>A 2016 <a href="https://pubs.acs.org/doi/full/10.1021/acs.est.6b04447" target="_blank" rel="noopener noreferrer">study</a> by Harvard University researchers, published in <em>Environmental Science and Technology,</em> found that flooding reservoirs for hydroelectric projects in Canada would increase the risk of mercury poisoning in Indigenous communities at 90% of the dam sites.</p><p>When land is flooded for a reservoir, the microbes in the soil convert naturally occurring mercury into more dangerous methylmercury, which then works its way up the food chain. That puts anyone who relies on local wildlife such as fish, birds and seals at risk. In the northern reaches of Canada, that's largely Indigenous people.</p><p>The researchers looked at how three Inuit communities downstream of Nalcor's Muskrat Falls project would fare. And they found that, on average, risk of exposure for community members would double after the area was flooded. That could translate to higher risks for cardiovascular disease and neurodevelopmental delays for children.</p><p>The more people rely on local food sources, the more harm they're exposed to. And in this remote region where store-bought food is very expensive, that's a serious concern.</p>

<p>"People have a very high prevalence of economic insecurity and that translates into insecure access to Western foods at the grocery store," says Ryan Calder, a co-author of the study and now an assistant professor of environmental health and policy at Virginia Tech. "Traditional food systems account for a smaller and smaller fraction of overall calories, but a wildly disproportionate fraction of nutrient intake."</p><p>Despite this, he doesn't think their research should be taken as a commentary on whether hydroelectric power itself is good or bad. "We really just criticized [the company's] risk assessment," he says.</p><p>Earlier studies by Nalcor claimed the effect on the Inuit would be negligible as the mercury would quickly dilute in downstream waters.</p><p>"They had no basis for saying there was going to be no impact," says Calder. "It was clear that they were trying to ignore their obligations — if not legal, then certainly moral — to Indigenous people."</p><p>The researchers also found that about half of the other sites they studied would have equal or greater concentrations of methylmercury than Muskrat Falls.</p><p>Roberta Frampton Benefiel of <a href="http://www.grandriverkeeperlabrador.ca/" target="_blank">Grand Riverkeeper Labrador</a>, who lives near the Muskrat Falls project, says she wasn't surprised by Nalcor's position. "Aboriginal people don't count to this government and so we have to make the Aboriginal people count," she says.</p><p>She has spoken to environmental organizations in the United States to help raise awareness about some of the local effects of dam development in Canada.</p><p>"I want people in the United States to understand that when they flip their light switch, if they accept these power lines from Canada, they're poisoning northern communities," she says.</p>
<h3>More Dams?</h3><p>New York and Massachusetts have been eager for hydropower from Canada as long as it doesn't mean the construction of new dams for the transmission projects.</p><p>Hydro-Québec says it has enough reserves for export to New York and Massachusetts without redirecting power from its existing United States or Canadian customers.</p><p>It's nearly finished with the last dam in the complex of four generating stations on the Romaine River, which along with other projects, has added 5,000 megawatts of capacity over the last decade. Although it does has the <a href="https://www.nerc.com/pa/RAPA/ra/Reliability%20Assessments%20DL/NERC_LTRA_2019.pdf" target="_blank" rel="noopener noreferrer">lowest reserve margin</a> of utilities in the region, according to the North American Electric Reliability Corporation's 2019 assessment.</p><p>In previous years Hydro-Québec did preliminary work to explore the possibility of new dams on the Little Mécatina River, but company spokesperson Lynn St-Laurent says they currently have no plans for new dams and that project is no longer in their strategic plan.</p><p>Gary Sutherland, director of strategic affairs for northeast markets at Hydro-Québec, says that additional energy demand for export could be met with increased energy efficiency in Quebec and more wind projects. Quebec Premier François Legault <a href="https://twitter.com/francoislegault/status/1316155854610001920" target="_blank" rel="noopener noreferrer">tweeted last week</a> that the province's next addition of capacity, if needed, would be the 200-megawatt <a href="https://energycentral.com/news/quebec-interest-wind-power-projects-back-horizon" target="_blank" rel="noopener noreferrer">Apuiat wind farm</a>.</p><p>Elsewhere in Canada, however, dam building continues.</p><p>Manitoba Hydro and four First Nations are in the process of building the <a href="https://www.enr.com/articles/45695-mega-canadian-hydro-project-moves-forward-despite-surprises-bitter-cold" target="_blank" rel="noopener noreferrer">Keeyask project</a>, a 695-megawatt hydroelectric generating station on the Nelson River.</p><p>British Columbia also continues to muddle along on development at Site C, a 1,100-megawatt dam on the Peace River that has faced mounting problems and protests.</p>

<p>This includes, according to a report in <em><a href="https://thenarwhal.ca/topics/site-c-dam-bc/" target="_blank" rel="noopener noreferrer">The Narwhal</a></em>, legal challenges from "landowners and First Nations who oppose flooding 128 kilometers of the Peace River and its tributaries, putting Indigenous burial grounds, traditional hunting and fishing areas, habitat for more than 100 species vulnerable to extinction and some of Canada's richest farmland under up to 50 meters of water."</p><p>Construction has also <a href="https://vancouversun.com/business/site-c-still-scaling-up-construction-to-meet-important-milestone-while-remains-up-in-the-air" target="_blank" rel="noopener noreferrer">uncovered geological issues</a> that could make parts of the foundation unstable, prompting <a href="https://www.cbc.ca/news/canada/british-columbia/site-c-letter-1.5741443" target="_blank" rel="noopener noreferrer">numerous calls</a> to stop development.</p><p><a href="https://1694d3a6-ec13-42ea-a8f0-a29cda354660.usrfiles.com/ugd/1694d3_b5baab11560f4bf4a3910e992c608509.pdf" target="_blank" rel="noopener noreferrer">New research</a> by energy analyst Robert McCullough, who runs a Portland, <a href="https://www.mresearch.com/" target="_blank" rel="noopener noreferrer">Oregon-based consulting firm</a>, found that if the project continues its likely to have surplus energy that will need to be sold outside the province at a loss to ratepayers.</p><p>But a poor financial outlook doesn't always mean the end of dam projects in Canada.</p><p>In Labrador Nalcor also has another large project planned — the 2,250-megawatt Gull Island dam, farther upstream from Muskrat Falls, which could be built if there's a buyer for the power.</p><p>It's a prospect Benefiel finds shocking, considering the company's most recent project was so over budget that it prompted a provincial <a href="https://www.muskratfallsinquiry.ca/" target="_blank">Commission of Inquiry</a>, which found that Muskrat Falls put the financial health of the entire province at risk.</p>
<h3>Is Hydro Needed?</h3><p>Considering all the complexities of hydro projects and the related transmission infrastructure, is it necessary to move U.S. states off fossil fuels and toward clean energy goals?</p><p>That depends on who you talk to.</p><p>Despite investment in wind and solar, "hydro has a couple of things going for it," says Rothstein of the Northeast Clean Energy Council. The first is that it's able to compete on costs, and second is the "dispatchability."</p><p>Thanks to decades of dam building, Canadian hydropower is ready to go — pending transmission capacity. It's also seen as less variable than wind and solar, although hydropower does fluctuate by season and by year, depending on precipitation.</p><p>"I think hydro will play a role, but it's not going to be the only resource," says Rothstein. Offshore wind holds the biggest potential for large-scale projects in the region, he says.</p><p>New York has already awarded contracts to procure <a href="https://www.utilitydive.com/news/new-york-awards-record-1700-mw-offshore-wind-contracts/559091/" target="_blank" rel="noopener noreferrer">1,700 megawatts of offshore wind</a> and in July <a href="https://renewablesnow.com/news/new-york-opens-procurement-round-for-4-gw-of-renewables-707197/" target="_blank" rel="noopener noreferrer">put out a call</a> to solicit another 2,500 megawatts of offshore wind and 1,500 megawatts of land-based, large-scale renewables.</p><p>Massachusetts is making strides toward wind energy, too. In 2016 Gov. Charlie Baker signed an energy bill requiring the state's utilities to<a href="https://www.wbur.org/earthwhile/2019/05/31/more-offshore-wind-power-massachusetts" target="_blank"> procure 1,600 megawatts of offshore wind</a> and could soon double that.</p>

<p>All told around a half a dozen major projects now await a green light, pending permitting decisions by the federal Bureau of Ocean Energy Management.</p><p>All down the East Coast, "there's a whole constellation of projects close to breaking water," says Rothstein.</p><p>In the past offshore wind has been stymied by NIMBYism, but he says both the public perception of wind has changed and so have costs.

Construction of a hydropower plant in the only known habitat of a critically endangered orangutan species on the Indonesian island of Sumatra might be delayed for up to three years due to COVID-19 and funding issues.
<p>Muhammad Ikhsan Asaad, who oversees the project for state-owned utility PLN, said the Batang Toru plant was supposed to start operating in 2022, based on the agreement between PLN and project developer PT North Sumatra Hydro Energy (NHSE).</p><p>"But it might be delayed to 2025, mainly because the drawdown from lender Bank of China is stopped due to environmental concerns as well as COVID-19," he <a href="https://www.dunia-energi.com/proyek-plta-batang-toru-molor-hingga-2025/" target="_blank">said</a>.</p><p>In construction, a drawdown refers to a situation in which a company receives part of the funding necessary to complete a project, and the rest of the funding might be disbursed gradually over the course of the project.</p><p>The project is <a href="https://www.gatra.com/detail/news/426148/politik/plta-batang-toru-selesai-akhir-tahun-2020" target="_blank">estimated to cost</a> $1.68 billion, financed through equity and loans.</p><p>NSHE <a href="https://alert-conservation.org/issues-research-highlights/2018/7/9/alert-scientists-lobby-indonesian-president-to-save-worlds-rarest-ape" target="_blank">initially sought loans</a> from funders like the World Bank's International Finance Corporation (IFC) and the Asian Development Bank (ADB). But following the description of a new orangutan species, the Tapanuli orangutan (<em>Pongo tapanuliensis</em>), in the Batang Toru ecosystem in northern Sumatra in 2017, environmentalists have called for the project to be stopped or at least <a href="https://news.mongabay.com/2020/03/tapanuli-orangutan-batang-toru-nshe-iucn-ape-dam/" target="_blank">halted to allow</a> for an independent scientific study of its impact on the newly known species.</p><p>They say the project might <a href="https://news.mongabay.com/2018/05/rarest-apes-path-to-survival-blocked-by-roads-dams-and-agriculture/" target="_blank">devastate</a> the most critical areas of the Batang Toru ecosystem and drive the Tapanuli orangutan to extinction. Only 760 of the great apes are estimated to survive in a tiny tract of forest less than one-fifth the size of the metropolitan area that comprises Indonesia's capital, Jakarta.</p><p>Shortly after its description, the Tapanuli orangutan was categorized as critically endangered on the IUCN Red List due to its decreasing population trend — <a href="https://news.mongabay.com/2017/12/the-worlds-newest-great-ape-revealed-a-month-ago-is-already-nearly-extinct-iucn/" target="_blank">down by 83% </a>in just three generations — and heavily fragmented distribution.</p><p>The IFC and ADB subsequently distanced themselves from the project. And in March 2019, the Bank of China, which is also involved in financing the project, said it had "noted the concerns expressed by some environmental organizations" and promised to carefully review the project. It has not issued any further public updates, leaving the funding for the project uncertain.</p>
<p>NSHE <a href="https://news.mongabay.com/2019/12/indonesian-dam-raises-questions-about-un-hydropower-carbon-loophole/" target="_blank">has previously confirmed</a> that the project's funding was in doubt as a result of campaigns against the dam.</p><p>PLN director Zulkifli Zaini said environmental issues were among the reason why the project might be delayed.</p><p>"It is true that the project faced hurdles from NGOs over environmental issues," he said. "There are apes and other [animals] there."</p><p>The coronavirus outbreak has also proved to be a setback, with the work on the hydropower plant put on hold since January after construction workers from Chinese state-owned contractor Sinohydro, who had gone home for the Lunar New Year holiday, were barred entry back into Indonesia over health concerns.</p><p>NSHE has submitted a request to PLN, as the buyer of the plant's power, to push the start of the dam's operation to 2025. But the utility said a decision hadn't been made yet.</p>
<p>"NSHE and PLN are still in the stage of discussion or collective review regarding the target of the Batang Toru hydropower dam operational target," NSHE spokesman Firman Taufick said. "Whatever the result of the discussion between NSHE and PLN, we will always follow the policy and direction from PLN."</p><p>A decline in electricity consumption as a result of suspended economic activity during the pandemic is <a href="https://www.thejakartapost.com/paper/2020/06/21/1-5b-batang-toru-hydropower-plant-may-be-delayed-by-years.html" target="_blank">another factor</a> that could delay the project, according to Riza Husni, chairman of APPLTA, a national association of hydropower plant developers.</p><p>Dana Tarigan, the head of the North Sumatra chapter of the Indonesian Forum for the Environment (Walhi), said he hoped PLN would take into account the environmental concerns over the project in making a decision.</p><p>"We're hoping PLN could see the rejection well," he told Mongabay. "There's not only the problem with COVID-19, but also rejections from many parties, whether it's because of [the potential impact on] the orangutan and other biodiversity, or on the safety of the people [living in nearby areas]."</p><p><span></span>Dana said Walhi had staged a protest in 2018 against the project outside the offices of PT Pembangkit Jawa Bali (PJB) Investasi, a subsidiary of PLN that serves as the project sponsor and a shareholder in the Batang Toru power plant.</p><p>The protesters demanded that PJB Investasi, which holds a 25% stake in NSHE, to withdraw from the project.</p><p>Dana also urged PLN to take into account a recent <a href="http://static1.1.sqspcdn.com/static/f/1200343/28292859/1588408298700/BatangToruFactcheckReport.pdf?token=nj9gUyDjXX4hT%2Bx1lW5KLZgXV1M%3D" target="_blank">fact-check report</a> by the IUCN that analyzes the many contradictory claims being made about the project's potential impacts, specifically assertions made by NSHE.</p>

<h3><strong>Fact-Checking</strong></h3><p>The report identifies several significant claims found in NSHE's publications or press releases as being inaccurate or misleading.</p><p>"In at least ten cases, assertions made in public-facing NSHE literature or on the NSHE website are found to be inconsistent with findings presented in earlier impact assessments conducted on behalf of NSHE," the report says.</p><p>The report also finds other claims made by NSHE contradict findings in peer-reviewed literature and technical reports.</p><p>"Some of these relate to the most controversial aspects of the project such as its impact on the Tapanuli orangutan and the ecology of the Batang Toru river, the demand for the power that the plant would produce, and the project's compliance with international investment standards," the report says.</p><p>Emmy Hafild, a senior adviser to NSHE's chairman, said the report mistakenly accounted for the whole project permit area, instead of its actual footprint, to assess its potential impact on the orangutan. She also said the permit area referred to in the report was based on the company's permit area during exploration stage, which was larger than the current permit area post-exploration.</p><p>"The IUCN fact check report is clearly wrong," Emmy said. "The report uses data that's already outdated and this is the location permit, not the footprint of the project."</p><p>Serge Wich, the co-vice chair of the IUCN primate specialists' section on great apes (SGA) and one of the researchers who described the Tapanuli orangutan, said it's clear the IUCN report refers to the whole permit area in fact-checking the company's claim.</p><p>"[A]nd we have always said that this indicates the maximum impact," he told Mongabay.</p><p>Wich said that while the project might not occupy the full area, its impact on the orangutan could still be devastating due to the location of the project, which lies at a key location for connectivity between the orangutan's subpopulations, split up across three separate blocks: west, east and south. By locating the dam there, the project would jeopardize that connectivity, he said.</p><p>Emmy denied the location of the project would impact the potential for a future forest corridor linking the western and southern populations of the orangutan.</p><p>"The footprint of the project has been checked by our friends [researchers] and it will not disturb the corridor," she said.</p><p>Wich said that might not be the case, as the latest Batang Toru ecosystem map provided by NSHE clearly shows that the project area is "a long wall-like structure cutting those three areas from each other."</p>

<p>Didik Prasetyo, an orangutan researcher at Jakarta's National University, who conducted a study on the project, said he's confident the hydropower dam will not threaten the orangutan as long as NSHE sticks to his recommendations. Among them: limiting the amount of traffic passing over the project's roads; and designing the project's overhead power lines to allow the orangutans to travel safely beneath them.</p><p>"If it's safe, then [the orangutans] will not be scared to briefly walk on the ground [to cross from one population to another]," Didik said. "The width of the road is not too dangerous for the orangutans if there's no one passing on the road. So we're recommending the traffic be limited to particular hours."</p><p>He said rehabilitating impacted areas is also crucial.</p><p>"We're recommending to the company that there are three areas that will be impacted significantly if the company doesn't manage [the project] sustainably," Didik said. "So we recommend these most-threatened areas to be restored as soon as possible."</p><p>He said there are 273 hectares (585 acres) of orangutan habitat in the project area, of which 84 hectares (207 acres) will be used as a location for permanent buildings by the company. The remaining 189 hectares (467 acres) will be reforested, he added.</p><p>NSHE said it will offset permanent forest loss caused by the project by planting trees in other areas, while temporary forest loss will be restored.</p><p>The IUCN report, however, says restoring affected areas might not be feasible. NSHE literature identifies heaps of dug-up dirt as the areas intended for restoration, but the IUCN says this might not be realistic because these areas consist of large amounts of unconsolidated material.</p><p>"The material is from underground and is potentially sterile to rehabilitation efforts and/or volatile to erosive processes," the report says.</p>

The conclusion to decades of work to remove a dam on the Middle Fork Nooksack River east of Bellingham, Washington began with a bang yesterday as crews breached the dam with a carefully planned detonation. This explosive denouement is also a beginning.

<p>Over the next couple of weeks, crews will fully remove the 125-foot-wide, 25-foot-tall dam, allowing the Middle Fork Nooksack to run free for the first time in 60 years. With the dam's removal, 16 miles of river and tributary habitat will open up to help boost populations of three threatened Puget Sound fish species: Chinook salmon, steelhead and bull trout.</p><p>"This project has always ranked at the top of the list for fish recovery projects in this area because of the sheer number of miles of river habitat that are available upstream in a fairly remote and pristine area," says Renee LaCroix, assistant public works director for the city of Bellingham, which owns the dam. "There's no other single project in this area that can match this."</p><p>Two local tribes, the Nooksack and Lummi Nation, have been behind the effort to help restore fish passage and the river's ecological integrity.</p><p>"Our natural resources are our cultural resources," says Trevor Delgado, the Nooksack tribal historic preservation officer. "With this removal we get a little piece of our home back — a place where our people have visited for hundreds of generations."</p><p>LaCroix says the project has no downsides for the city, and it's expected to increase the resilience of the municipal water supply, remove a safety hazard for kayakers, help fish recovery and restore culturally significant resources for the tribes.</p><p>Proponents also hope to see indirect benefits for <a href="https://therevelator.org/save-southern-resident-killer-whales-extinction/" target="_blank">endangered Southern Resident killer whales</a>. This population of orcas ranges across Pacific Northwest coastal waters and <a href="https://www.mmc.gov/priority-topics/species-of-concern/southern-resident-killer-whale/" target="_blank">relies on dwindling numbers of Chinook</a> as a main food source. Fewer than 80 of the whales remain, and Chinook populations have fallen so low that the orcas have started <a href="https://www.q13fox.com/news/chinook-salmon-decimated-southern-resident-orcas-are-residents-no-more" target="_blank">altering their traditional migration patterns</a> as they search for fish to eat.</p><p>But even with the dam removal's many benefits and municipal and tribal support, the path to this moment hasn't been easy.</p>
The History
<p>The Middle Fork Nooksack drains glacier-fed headwater streams that run off the icy summit of 10,778-foot Mt. Baker. The Middle Fork joins the North Fork and then the mainstem of the Nooksack River, which travels to Bellingham Bay and Puget Sound. The entire Nooksack watershed stretches 830 square miles across Washington and into British Columbia.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzQ1ODg5Ny9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY0OTM4MjU3OX0.xukdfxAnfHt_A24vvWHf30SCX0R9jk3qcWK6PcBHyhI/img.png?width=980" id="c3923" class="rm-shortcode" data-rm-shortcode-id="0033be9942c3db23fca400a4533dfc6e" data-rm-shortcode-name="rebelmouse-image" data-width="1024" data-height="513" />
American Rivers
<p>For generations the river and its surrounding habitat have physically and spiritually nourished Indigenous peoples — including the Nooksack Indian Tribe and the Lummi Nation.</p><p>But all that changed when the dam was built in in 1961 to divert water to the city of Bellingham to supplement its main water supply in Lake Whatcom — the drinking water for the now-85,000 residents in the city and county. As soon as it went up, the dam obstructed fish passage, altered the river's flow, and disrupted the ability of tribal members to use a culturally significant area.</p><p>For the past four decades, Delgado says, the Nooksack have pushed for dam removal. They got close in the early 2000s, when the Nooksack and Lummi Nation entered into an official agreement with the city and state to work on a solution that would allow fish passage, including the possible installation of fish ladders. But despite years of work, a suitable fix wasn't found, and the effort had completely stalled by 2016.</p><p>The following year the nonprofit <a href="https://www.americanrivers.org/" target="_blank">American Rivers</a>, which works on watershed restoration and has extensive experience in dam-removal efforts, stepped in with financial backing from the Paul G. Allen Family Foundation. American Rivers' April McEwan assumed a project management role and brought parties back to the table and soon into agreement on a plan to remove the dam and reengineer the city's water intake from the river.</p><p>"What we know about dam removal is that if you can remove the infrastructure and restore the channel to natural conditions, that's always the best way to get fish passage," says McEwan.</p><p>The final cost of the project came in at around $20 million — way more than the city could afford on its own. About half of the cost eventually came from the state and the city is collaborating with federal agencies on the distribution of another $2 million in Pacific Salmon Treaty funds. But before applying for that money, the city had to complete costly initial design and permitting work. Private foundations — largely the Paul G. Allen Family Foundation, along with Resources Legacy Fund — picked up 70% of those initial costs.</p><p>LaCroix says help from American Rivers and the foundations was hugely important in getting the project "shovel ready" so it could apply for the construction funds it needed.</p><p>Removing the dam infrastructure was just part of the cost, though. Reworking the city's water intake also required some tricky engineering.</p>
A Plan Comes Together
<p>The Middle Fork dam is not a pool dam built for water storage. Much of the time, water flows over the top until dam operators drop a floodgate to divert water to new locations. That water travels about 14 miles through tunnel and pipeline to Mirror Lake, then Anderson Creek, and to Lake Whatcom before finally being delivered to residents' taps.</p><p>Before removing the dam, engineers had to move the water intake 700 feet upstream and situate it at an elevation that still enabled city water withdrawals throughout the year, regardless of flow conditions.</p><p>They also needed to make sure that the rushing water didn't sweep up fish and accidentally send them through the water-supply system.</p><p>"The solution required a fairly complex design in the intake structure, including a fish exit pipe out of that structure to put fish back into the river in a way that meets current environmental permit standards," explains LaCroix.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzQ1ODk1Ny9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxOTcxODcyN30.stOgraXNQZGmfADeQUdXCB2RR3Aka6FwLOxl377s-3w/img.jpg?width=980" id="7669a" class="rm-shortcode" data-rm-shortcode-id="7ee070ad97b1353f5baa7c8886acb341" data-rm-shortcode-name="rebelmouse-image" data-width="1024" data-height="513" />

<p>Despite the cost and the work, she says, being able to continue to meet their municipal water obligations while opening up habitat for threatened species has been a win-win.</p><p>"I think there's a lot of benefits to having a dam removal versus fish passage — the main one being that you get a free-flowing river that can be a dynamic ecosystem and change over time," she says. "A static fish ladder just can't provide that same level of ecosystem benefit."</p>Restoration Success
<p>Despite local authorities' championing dam removal on the Middle Fork, the project has largely flown under the radar, overshadowed in the Pacific Northwest by heated discussions about a much larger potential project — removing <a href="https://www.seattletimes.com/seattle-news/feds-reject-removal-of-4-snake-river-dams-in-key-report/" target="_blank">four federal hydroelectric dams on the lower Snake River</a>, a major tributary of the Columbia River.</p><p>Proponents of dam removal there see it as the best chance for recovering threatened salmon populations, including Chinook, which could help starving Southern Resident killer whales. Those dams also provide irrigation water, barge navigation and hydropower, so there's been more pushback against removal efforts.</p><p>Previous dam removals around the country, however, have proved successful at aiding fish recovery and river restoration.</p><p>Most notably the 1999 demolition of <a href="https://therevelator.org/edwards-dam-removal/" target="_blank">Edwards Dam on Maine's Kennebec River</a> restored the annual run of alewives, a type of herring essential to the food web. The fish run has gone from zero to 5 million in the two decades since dam removal. Blueback herring, striped bass, sturgeon and shad have also extended their reach. And the resurgence has brought back osprey, bald eagles and other wildlife, too.</p><p>The overwhelming success of river restoration on the Kennebec helped to spur a nationwide dam removal movement that's now seen 1,200 dams come down since 1999. Last year a record <a href="https://www.americanrivers.org/conservation-resource/a-record-26-states-removed-dams-in-2019/" target="_blank">90 dams</a> were removed in 26 states, including <a href="https://therevelator.org/cleveland-forest-dam-removal/" target="_blank">20 dams in California's Cleveland National Forest</a>.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzQ1ODk4MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NjM5NTQ0Nn0.X2icIzmemq9oxKqfGRz4nox9rsOYZMTgUCLbCTGc5ZE/img.jpg?width=980" id="e9db0" class="rm-shortcode" data-rm-shortcode-id="7f227785f21cb59b1ff2fd70db6ccc6c" data-rm-shortcode-name="rebelmouse-image" data-width="1024" data-height="576" />

<p>The results have been seen in the Pacific Northwest, as well, which boasts the largest dam removal thus far in the country. In 2011 and 2014, the demolition of <a href="https://therevelator.org/elwha-dam-removal/" target="_blank">two dams</a> on Elwha River, which runs through Washington's Olympic National Park, opened up 70 miles of habitat that had been blocked for a century. Scientists have started seeing all five species of salmon native to the river coming back, particularly Chinook and coho. Bull trout, they've observed, have increased in size since the dams were removal.</p>Benefits on the Middle Fork Nooksack
<p>McEwan hopes to see a similar outcome on the Middle Fork.</p><p>Like the Elwha the Middle Fork Nooksack is a relatively pristine river with little development, and dam removal is expected to provide a big boost to fish. The additional miles of spawning habitat are important, but so is the temperature of that water.</p><p>The dam removal will open access to cold upstream waters, which are ideal for salmon and getting harder to come by as climate change warms waters and reduces mountain runoff.</p><p>"This is really great for the climate change resiliency for these species," says McEwan.</p><p>Steelhead will get back 45% of their historic habitat in the river, and scientists expect Chinook populations to increase in abundance by 31%.</p><p>That <em>could</em> help Southern Resident killer whales.</p><p>"When you get to the ocean, it's a little bit of a black box in terms of what you can model and say definitively is going to help, but more fish is better for orcas," McEwan says.</p><p>Upstream habitat will see benefits, too.</p><p>Oceangoing fish like salmon enrich their bodies with carbon and nitrogen while at sea. When they return to their natal rivers to spawn and die, the marine-derived nutrients they carry back upriver become important food and fertilizer for both riverine and terrestrial ecosystems — aiding everything from trees to birds to bears.</p><p>"Once the fish start making their way back, it will start changing the whole ecological system," says Delgado.</p><p><span></span>But any ecological benefit from salmon restoration, either in the ocean or the upper watershed, won't be immediate.<br></p><p>"The population of salmon on the Middle Fork is so low that we expect it's going to take quite a while to rebound," she says. "But the big picture is that what's good for salmon is good for the region — our history and our destiny are intricately intertwined."</p><p>After decades of work, that process of restoration has finally begun.</p>From Your Site Articles

Dams are often touted as environmentally friendly. Although they do represent a renewable source of energy, a closer look reveals that they are far from green. DW lays out the biggest environmental problems of mega-dams.
1. Dams Alter Ecosystems
<p>Water is life — and since dams block water, that impacts life downstream, both for ecosystems and people. In the case of the <a href="https://www.dw.com/en/ethiopia-egypt-sudan-make-slow-progress-in-nile-dam-row/a-52015611" target="_blank">Grand Ethiopian Renaissance Dam (GERD)</a>, which is being built in Ethiopia and is set to be Africa's largest source of hydroelectric power, Egypt is concerned it will receive less water for things like agriculture.</p><p>Downstream ecosystems rely not only on water, but also on sediment, both of which are held back by big dams. As solid materials build up in a manmade reservoir, downstream land becomes less fertile and riverbeds can become deeper or even erode away. <a href="https://www.pnas.org/content/115/47/11891" target="_blank">Emilio Moran</a>, a professor of geography and environment at Michigan State University in the US, described sediment loss of 30 to 40% as a result of large dams.</p><p>"Rivers carry sediment that feeds the fish, it feeds the entire vegetation along the river. So, when you stop sediment flowing freely down the streams, you have a dead river."</p><p>And ecosystems may have adapted to natural flooding, which dams take away. </p><p>Mega-dams also often have a large footprint on land upstream. Aside from displacing human communities, flooding to create a reservoir also kills plants, and leaves <a href="https://www.dw.com/en/tanzanias-biggest-wildlife-reserve-under-threat/a-43902762" target="_blank">animals to drown or find new homes</a>. Reservoirs can also further fragment valuable habitat and cut off migratory corridors. </p>2. Dams Reduce Biodiversity and Cause Extinction
<p>Aquatic species, particularly fish, are vulnerable to the impacts of dams. Moran says the Itaipu Dam, which was constructed on the border between Paraguay and Brazil in the 1970s and 1980s, resulted in a 70 percent loss of biodiversity.</p><p>"On the Tucuruí Dam that was built in the 80s in the Amazon," he added, "there was a 60% drop in productivity of fish."</p><p>Many fish species rely on the ability to move about freely in a river, be it to seek food or return to where they were born. Migratory species are badly affected by the presence of dams. In 2016, the International Union for the Conservation of Nature (IUCN) reported a 99% drop in catches of <a href="https://www.dw.com/en/poaching-dams-imperil-ancient-danube-fish/a-43907515" target="_blank">sturgeon</a> and paddlefish — both of which are migratory — over a period of three decades. Overfishing and river alteration were cited as major threats to the species' survival. </p><p>A <a href="http://www.mrcmekong.org/highlights/the-study-on-sustainable-management-and-development-of-the-mekong-river-including-impacts-of-mainstream-hydropower-projects/" target="_blank">2018 study</a> predicted that fish stocks on <a href="https://www.dw.com/en/a-dam-building-race-threatens-the-mekong-river/a-50049206" target="_blank">Asia's Mekong River</a> could drop by 40% as a result of dam projects – with consequences not only for biodiversity, but for the people whose lives and livelihoods depend on those fish.</p><p>The stakes for biodiversity are particularly high for animals threatened with extinction. And not only for aquatic species. The <a href="https://www.dw.com/en/new-orangutan-species-found-in-indonesian-forest/a-41217498" target="_blank">Tapanuli orangutan</a> — the Earth's rarest ape, with only 500 individuals left — could finally be pushed to the brink if a planned hydroelectric project in Sumatra, Indonesia, is completed. Dams can literally snuff out species. </p>3. Dams Contribute to Climate Change (and Are Affected by It)
<p>As reservoirs fill, upstream forests are flooded, eliminating their function as carbon sinks. As the drowned vegetation decomposes, decaying plants in manmade reservoirs release methane, a powerful greenhouse gas. That makes reservoirs sources of emissions — particularly those in <a href="https://www.dw.com/en/forest-sos-earths-green-lungs-disappear/a-44908586" target="_blank">tropical forests</a>, where there is dense growth. It's estimated that greenhouse gas emissions from dams amount to about <a href="https://academic.oup.com/bioscience/article/66/11/949/2754271" target="_blank">a billion tons annually</a>, making it a significant global source.</p><p>And as the climate changes, more frequent and prolonged drought means dams will capture less water, resulting in <a href="https://www.dw.com/en/hydropower-supply-dries-up-with-climate-change/a-42472070" target="_blank">lower electricity production</a>. Countries dependent on hydropower will be especially vulnerable as temperatures keep rising. </p><p>Moran described a vicious circle, for example in Brazil, which gets 60 to 70% of its energy from hydropower: "If you wipe out half the rainforest, there will a loss of half the rainfall. And then there won't be enough water to provide the amount of power from those dams," he explained. </p>4. Dams Reduce Water Quality
<p>Manmade reservoirs trap fertilizers that run into the water from surrounding land. In addition, in some developing countries, sewage flows directly into the reservoirs. This kind of pollution can result in algae blooms that suck the oxygen out of the water, making it acidic and potentially harmful to people and animals.</p><p>Still water in large manmade lakes is warm at the top and cold at the bottom, which can also affect water quality. While warm water promotes the growth of harmful algae, the cold water that is often released through turbines from the bottom of a reservoir may contain damagingly high mineral concentrations. </p><p>In some cases, water in manmade reservoirs is of such bad quality that it is not even fit to drink. </p>5. Dams Waste Water
<p>Since more surface area of the water gets exposed to the sun, reservoirs result in much more evaporation than the natural flow of the river before that dam existed. It's estimated at least 7% of the total amount of freshwater needed for human activities evaporates from the world's reservoirs every year.</p><p>This effect is made worse in hot regions, Moran pointed out. "Certainly if you had a reservoir in a tropical area with high temperatures, there is going to be a lot of evaporation," he said. And big reservoirs "are, of course, evaporating constantly."</p><p>Reservoirs are also a haven for invasive plant species, and weed-covered reservoir banks can lead to evapotranspiration — or the transfer of water from the land to the atmosphere through evaporation from soil and transpiration from plants. Such evapotranspiration amounts to six times more than the evaporation from the water's surface. And there is even evidence that dams increase water use and promote water waste by creating a false sense of water security. </p><p>In the face of <a href="https://www.dw.com/en/water-shortages-pose-growing-risk-to-global-stability/a-50394997" target="_blank">dwindling global freshwater resources</a>, some question whether dams should be reconsidered. </p>So What Are the Alternatives?
<p>The evidence is damning. But if mega-dams have so many harmful environmental effects, what are the alternatives? Although some green groups point to small hydropower as being more ecologically sound, Moran is skeptical. "A dam is a dam - it's blocking the fish, it's blocking the sediment."</p><p>He pointed to the need to consider not just how to maximize energy production, but also maintain ecological productivity. One option he cited is the use of in-stream turbines. </p><p>And many environment advocates agree that other renewable energies such as solar and wind can provide clean electricity at a far lower environmental cost. </p>From Your Site Articles

Around 10,000 people were forced to evacuate their homes in central Michigan after heavy rain prompted what the National Weather Service called "catastrophic failures" at two dams.
<p>The Edenville and Sanford dams collapsed Tuesday night, threatening to drench the town of Midland, Michigan under nine feet of water, <a href="https://www.reuters.com/article/us-usa-flood-michigan/michigan-governor-declares-emergency-after-dams-collapse-idUSKBN22W071" target="_blank">Reuters reported</a>.

It currently has 53,009 confirmed cases, according to <a href="https://coronavirus.jhu.edu/map.html" target="_blank">Johns Hopkins University data</a> as of Thursday morning, the seventh highest total in the U.S.</p><p>"It's hard to believe that we're in the middle of a 100-year crisis, a global pandemic, and we're also dealing with a flooding event that looks to be the worst in 500 years," Michigan Governor Gretchen Whitmer said, as The New York Times reported.</p>
<div id="75598" class="rm-shortcode" data-rm-shortcode-id="dfc9460186b20166593cfef9d16e3a22"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1262933097437372417" data-partner="rebelmouse"><div style="margin:1em 0">[email protected] declared a state of emergency for @midlandcountymi after the Edenville & Sanford Dams breached. “If yo… https://t.co/TH05rXRSOe</div> — Michigan.gov (@Michigan.gov)<a href="https://twitter.com/migov/statuses/1262933097437372417">1589941689.0</a></blockquote></div>
<p>Much of the town of Midland, Michigan, which has a population of 42,000, was inundated with record flooding Wednesday, <a href="https://www.wunderground.com/cat6/aging-dams-changing-climate-a-dangerous-mix" target="_blank">Weather Underground reported</a>. The Tittabawassee River gauge at Midland measured a water level about one foot above the previous record of 33.89 feet as of 2 p.m. local time. The river was expected to crest in the afternoon and evening, the National Weather Service said.</p>

<p>No deaths or injuries have been reported, according to The New York Times, but the event puts further pressure on residents and businesses already reeling from the impact of the coronavirus.</p><p>"It's disastrous," evacuee Sue Baranski from neighboring Sanford told The New York Times. "Between the devastation from the flooding and the virus and the small-business owners trying to make their way through that, it's just too much."</p>

<p>The flooding is the result of two environmental crises and may be the author of a third.</p><p>First, there's the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>. Warming temperatures are expected to increase precipitation in northern midlatitudes and lead to more intense periods of rainfall in many places, including the U.S., as Weather Underground pointed out. In Michigan, this process is already underway. 2019 was its wettest year on record, and Midland is 1.35 feet of rainfall away from its wettest May on record. Its rainfall total for Monday and Tuesday was its third highest on record.<br></p><p>Then there's the state of one of the dams that failed. Federal regulators had warned for more than 20 years that the spillways at the Edenville Dam were not up to handling a major flood, <a href="https://edition.cnn.com/2020/05/20/politics/ferc-edenville-dam-midland-michigan-flooding/index.html" target="_blank">CNN reported</a>. However, they waited more than 13 years to crack down on the private company that operated the dam when it failed to comply, finally revoking its license in 2018. Oversight of the dam also passed from the federal government to the state of Michigan that year. Whitmer has promised an investigation of dam operator Boyce Hydro.</p>
<p>"This incredible damage requires that we hold people responsible," Whitmer said, as <a href="https://www.huffingtonpost.co.uk/entry/michigan-governor-warns-floods-peak_n_5ec569b6c5b6ea08c805eaeb?ri18n=true" target="_blank">HuffPost reported</a>. "This was a known problem for a while and that's why it's important that we do our due diligence and take action."</p><p>The flood also has the potential to cause lasting environmental damage as Dow Chemical confirmed Wednesday that flood waters were "commingling with on-site containment ponds," <a href="https://www.npr.org/2020/05/20/859333402/catastrophic-dam-failures-in-michigan-force-thousands-to-evacuate" target="_blank">NPR reported</a>.

Removing one gigantic dam can have a massive effect on restoring a river ecosystem.
<p>But bringing down more than 80 smaller dams? That can also cause a transformation.<em></em><span class="redactor-selection-marker" id="selection-marker-1"></span></p>
<p>This spring the Forest Service, aided by U.S. Marine Corps members, will blast apart 13 more dams in the <a href="https://www.fs.usda.gov/recarea/cleveland/recarea/?recid=47402" target="_blank">Trabuco ranger district</a> in Southern California's Cleveland National Forest.</p><p>It's the last phase of a groundbreaking project that began more than five years ago to remove a total of 81 dams from four streams in the mountains of Orange County.</p><p>"Nobody's really taken on a project this large and with this many partners and methods," says Forest Service fish biologist Julie Donnell, who's been working on the project.</p><p>The mammoth undertaking is designed to help boost populations of native aquatic species — most importantly Southern California steelhead (<em>Oncorhynchus mykiss</em>), which are federally listed as endangered.</p>
<p>It may also be a crucial learning tool due its sheer scope. Last year an estimated 90 dams were removed across the country, and nearly a quarter of those were in the Cleveland National Forest. That makes what's happening in California the place to watch as organizations plan for other multi-dam removal efforts around the country.</p><p>"Looking at what the Forest Service did is a really smart way for other agencies to begin to think about their infrastructure," says Serena McClain, the director of river restoration at the nonprofit American Rivers, which <a href="https://www.americanrivers.org/2020/02/record-number-of-states-26-remove-dams-in-2019/" target="_blank">tracks dam-removal efforts</a>. "The Forest Service is showing that the federal government can lead on this and demonstrate the possibility for the private sector and municipalities."</p><p>In addition to the work in the national forest itself, the ecological success of the project hinges on a downstream effort to remove two more barriers that prevent steelhead from reaching the forest as they migrate from the ocean.</p><p>The two projects have brought together a diverse, and unlikely, coalition of transportation departments, federal agencies, environmental nonprofits, local governments, and even the U.S. Marine Corps to help complete an ocean-to-headwaters restoration of more than 35 miles.</p><p>"This addresses one of the major threats to endangered southern steelhead," says Sandra Jacobson, the South Coast regional director of <a href="https://caltrout.org/" target="_blank">California Trout</a>, which is leading the downstream effort. "Once you open up the rivers, it allows a tremendous change in the accessibility of steelhead to their historical habitat so that they can go in and reproduce."</p>
A Group Effort
<p>Large dam removals, like those on the <a href="https://therevelator.org/klamath-dam-science/" target="_blank">Klamath River</a> in California and Oregon, or the <a href="https://therevelator.org/save-southern-resident-killer-whales-extinction/" target="_blank">hotly debated Snake River dams</a> in Washington, get lots of media attention. But smaller dam removals are quietly happening all across the country.</p><p>In the past 20 years around 1,100 dams have been removed in the United States — many of them aging, unsafe structures that had outlived their usefulness.</p><p>That's the story in the Cleveland National Forest, too.</p><p>Not a lot is known about the early history of the dams there, but most were likely built in the 1930s by the Civilian Conservation Corps, a public work program started to help Americans rebound from the Great Depression, says Kirsten Winter, a biologist in the Cleveland National Forest who has spearheaded the dam-removal project. It's not unusual for dams to be built in national forests, but this high a concentration of small dams may be a regional phenomenon in Southern California forests.</p><p>Most of these original dams would likely have washed away over time, but in the Cleveland National Forest, Orange County increased the size of the dams using native rock and mortar from the 1940s through the mid-1970s. Gates were lowered in the spring and raised in the fall to control the flow of the rivers. The impounded water was used mostly for fish stocking and recreation and was also available for fire suppression.</p><p>But eventually, Winter says, the dams aged, and the county got tired of maintaining them. Many washed out in storms. A few were removed in the 1980s by the county, and the gates were taken out of the remaining dams. Most fell back under Forest Service jurisdiction.</p><p>In recent years it became clear that some of the dams posed safety hazards and impeded fish migration. As part of a federal recovery effort to recover populations of endangered southern steelhead, a plan was developed to remove the 81 dams in the San Juan watershed on Upper San Juan Creek, Trabuco Creek, Holy Jim and Silverado Creek.</p><p>Projects of this scope require environmental assessments under the National Environmental Protection Act. Because the Forest Service had the forethought to take a watershed view of the project from the get-go they only needed to complete <a href="https://www.fs.usda.gov/nfs/11558/www/nepa/93703_FSPLT3_1606568.pdf" target="_blank">one environmental assessment</a> for the removal of the whole kit and caboodle, which helped make the permitting process more efficient.</p><p>With that in place, the dam-removal work began in December 2014. The project has a $1.2 million price tag, but the majority of funding hasn't come from the Forest Service itself.</p>

<p>The project has generated a lot of interest and a diverse array of partners, including California Department of Transportation, Federal Highways Administration, Orange County Parks, Orange County Transportation Authority, the U.S. Fish and Wildlife Service, California Department of Fish and Wildlife, and the U.S. Marine Corps. The coalition has brought funds, organizational support, technical knowledge and a lot of energy to the process.</p><p>"People are really pretty enthused about removing dams," says Winter.</p><p>Despite all the partners, it's still been a learning experience, she adds, because the dams vary so much in size and accessibility. Some are just a few feet high and 10 feet wide. Others reach 14 feet in height and stretch up to 100 feet across.</p><p>To breach the dams and break apart the mortar, crews employed a wide range of techniques. For sites near roads, they bought in conventional excavators. Steeper canyons required the use of a nimble "spider" excavator. Explosives took down a few dams where appropriate, while other places required sledgehammers and jackhammers. An extra bit of muscle (organizational and otherwise) came from a partnership with Marines from nearby Camp Pendleton. Corps members have helped remove 31 dams since 2018.</p>Ecological Benefits
<p>The biggest benefactors of the dam removals in the Cleveland National Forest will be steelhead — a type of salmonid. Like salmon, steelhead are anadromous, spending their time in both freshwater streams and the ocean. But unlike salmon that return to their natal headwater streams to spawn and die, steelhead will often spawn more than once.</p><p>They're also a key indicator species, says Jacobson. "When they disappear, that means there are probably multiple issues within a watershed."</p><p>In the San Juan, dams are one of them.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjg4NzU5OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0MDg1ODYxOX0.ni92xVjUCCNKaVujkcUyGcjm5Z5W5kbaM4Oro1VEPbI/img.jpg?width=980" id="989c4" class="rm-shortcode" data-rm-shortcode-id="2964b87f1da445926d3b21b372b6479d" data-rm-shortcode-name="rebelmouse-image" data-width="800" data-height="602" />

<p>"Dams create a very artificial situation," says Winter. "It's not just that they hold water, but they retain sediment and then they create these weird splash pools below."</p><p>Without the dams, the streams are able to create a more natural gradient and pool structure. That's good for other native wildlife like the arroyo toad and the arroyo chub, both federally listed as endangered, as well as the California newt, a California Species of Special Concern.</p><p>While the process of removing the dams can be a bit messy, "we've seen no negative effects to the habitat or to species due to the dam removal," says Donnell.</p><p>One of the biggest concerns with any dam removal is ensuring that any trapped sediment released from behind the structures doesn't cause ecological problems as it moves downstream. But Donnell says they've timed the removals to account for that and the streams naturally carry large sediment loads during storm events.</p><p>"We're actually doing some of dams in phases rather than all at one time because of the sediment load that's being held behind them," she says.</p><p>In areas where dams have been removed, Donnell has already noticed an improvement. "The bedload and sediment transport have been able to naturally flow once again," she says. "And the channel is starting to adjust back to a natural state."</p>A Connected Watershed
<p>As groundbreaking as the Cleveland National Forest's efforts are, the benefits for steelhead hinge on the downstream initiative.</p><p>Just five miles inland from Doheny State Beach, around the town of San Juan Capistrano, two barriers on Trabuco Creek block steelhead from 15 miles of upstream spawning habitat in the San Juan Creek watershed.</p><p>A quarter-mile-long concrete flood-control channel runs underneath five bridges, including the north- and southbound lanes of Interstate 5. The drop and the speed of water flowing through the hardened channel inhibits steelhead from making it through the gauntlet.</p><p>The second barrier sits a half-mile downstream, where another 20-foot drop under a bridge for the Metrolink regional railway poses an insurmountable roadblock for steelhead.</p><p>To solve both of these problems, California Trout is leading the multiagency design effort for a technical fish passage that will enable steelhead to navigate these obstacles using staggered weirs. At the I-5 obstacle, an additional fish transport channel will provide steelhead with an express lane to avoid the flood control channel and pass under the array of bridges.</p><p>The organization is working with fellow nonprofit Trout Unlimited, as well as Orange County's flood control district and public works office, the city of San Juan Capistrano, California Department of Transportation, and the Metrolink railroad association.</p><p>"We just received funding to complete the design," says Jacobson. The fish passages are expected to be completed around 2023 to 2025.</p>
<p>It's one part of a <a href="https://therevelator.org/california-steelhead-trout-watersheds/" target="_blank">larger regional effort</a> by the South Coast Steelhead Coalition, which consists of more than 35 organizations working to recover stable populations of the species in Southern California. Removing barriers to fish passage is a key element of the strategy, as are ensuring adequate water quantity and quality and removing nonnative species that compete for limited resources.</p><p>But there's one more objective: helping native rainbow trout. These resident trout are the same species as steelhead, but with a different life history — they don't migrate to the ocean. Since steelhead have been blocked from the upstream waters for nearly a century, resident trout populations have suffered from genetic isolation.</p><p>Only two resident trout populations remained in the region and one had to be emergency evacuated by a bucket brigade following the Holy Fire in 2018, which burned across the forest and threatened the water quality in the streams.</p><p>The removal of all the stream barriers — on and off the forest — will provide an opportunity for aquatic species to be more resilient. The wildfire is a perfect example of why that's needed, says Jacobson.</p><p>"It really gives the aquatic species the mobility they need to move around in response to drought, floods and wildfires," she says. "It's good for all sorts of species, too, not just fish."</p>
Ripple Effect
<p>With the dam removals in the Cleveland National Forest nearing completion, Donnell says she's hoping to soon begin presenting her data and methodologies so others can learn from the project.</p><p>"We've definitely heard from other forests and other districts wanting to know how we went about it, because this is new," she says.</p><p>McClain says American Rivers has been sharing the project's success story because it's a good example of how to think holistically about managing water and restoration opportunities for aquatic ecosystems.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjg4NzYwMS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2ODE1OTU0Mn0.GjFNEMdWLSYVMTxPkeNHiHBmusNo0miYD1EeZFUSMzs/img.jpg?width=980" id="df29e" class="rm-shortcode" data-rm-shortcode-id="1c958a8d85d9dd55c95135c3597ed6f7" data-rm-shortcode-name="rebelmouse-image" data-width="1024" data-height="768" />

<p>But it also makes sense fiscally. Why spend money maintaining dams we don't need?</p><p>"Even from a federal budget management perspective, we should be looking at where there may be projects on the federal books that are no longer serving a purpose," she says.</p><p>Thanks to the coordinated efforts in the San Juan watershed, southern steelhead will have a better chance of survival. But efforts to try and aid their recovery also have a larger benefit.</p><p>"We're not only restoring their environment, but also ours," Jacobson says. "We're actually improving the rivers overall."</p><p>And in the process, they may have established a model for mass dam removal across the country.</p>From Your Site Articles
