Cyanobacteria bloom at Clear Lake, Lake County, California, resulted in oxygen depletion in the water and the subsequent mortality of multiple aquatic species, including carp, catfish, bluegill and crappie. Kirsten Macintyre, California Department of Fish and Wildlife
Associated Press reported that algal blooms have been detected in more than 40 of the California's bodies of water—the highest number in state history. The blue-green cyanobacterium's growth has been fueled by
record-breaking heat and a historic drought.
"Warm temperatures, increased nutrients, and low water flows aggravated by drought conditions and climate change are favoring toxin-producing cyanobacteria and algae; and a number of lakes, reservoirs and river systems are suffering blooms as a result," the California State Water Resources Control Board announced last month.
As the Sacrameto Bee described, this green muck has been spotted across the Golden State:
"Since July, officials have issued notices about potentially toxic blue-green algae in the Klamath River near the Oregon border; along an arm of the state's largest reservoir, Shasta Lake; and at Pyramid Lake in Los Angeles County. They've attributed the deaths of thousands of fish along a section of Clear Lake to toxic blooms. Blue-green algae also has formed in parts of the Sacramento-San Joaquin Delta, prompting health warnings about green, malodorous water in Discovery Bay and Stockton."
Beverley Anderson-Abbs, an environmental scientist with the State Water Board, told AccuWeather that blooms are usually seasonal, "However, these seasons have been getting longer over the past few years as winters have been relatively warm and water, especially in smaller lakes, has been warming earlier in the year and staying warm later."
"It is very possible that this could get worse in the future as temperatures continue to increase and the possibility of future droughts along with that," Anderson-Ebbs said.
Harmful algal blooms can produce toxins that can cause serious illness in people. Wade Hensley, a resident of Discovery Bay, California was hospitalized after microcystin poisoning, a byproduct of algae. According to NPR, his body went numb from the waist down.
The California Department of Public Health states that algae exposure can cause rashes, skin and eye irritation, allergic reactions and other health effects but at high levels, "exposure can result in serious illness or death."
Over on the East Coast, the Chesapeake Bay and waterways beyond are seeing bigger and longer lasting algal blooms. The Daily Press reported that a strain of algae called Alexandrium monilatum has spread from Virginia Beach to the James, York and Rappahannock rivers to the Eastern Shore—even as far north as the Potomac River.
The report states that this year's bloom is still going strong even though it usually disappears by early to mid-September. Researchers are now trying to understand if Alexandrium has an impact on marine life. Currently, it does not appear to be harmful to humans.
"So the guidance is you should probably avoid it," Virginia Department of Health's marine science supervisor Todd Egerton told the Daily Press. "But, for the most part, people haven't reported any issues with it."
A number of other drivers can spur algae growth, from warming water to excess nitrogen and phosphorus runoff. Algal blooms have been known to strip oxygen from the water, creating a "dead zone" that threatens fish and other marine life.
The Clean Water Act Citizen Lawsuit against Perdue/Hudson gained another small victory in U.S. District Court when a motion to require defendants' documents to not be declared "confidential business information" was upheld.
On Nov. 17, both sides filed motions and supporting documents laying out their cases in U.S. District Court in Baltimore. The case is scheduled for trial in March 2012. To view the Waterkeeper’s Motion document, click here.
Assateague Coastal Trust (ACT) and Assateague Coastkeeper joined Waterkeeper Alliance to bring suit against Perdue Farms and one of their contracted growers in March 2010 for polluted discharges of fecal coliform, e.coli, nitrogen and phosphorus coming off the poultry growing facility into waterways connecting to the Pocomoke River and the Chesapeake Bay.
Perdue Farms and Alan Hudson were named in the lawsuit because one controls the poultry operation and the other is the owner/operator of the facility. Coastkeeper and Waterkeeper Alliance contend both should share responsibility for the polluted discharges.
A Perdue controlled website—savefarmfamilies.org—has been disseminating misleading and inflammatory statements and information related to this Clean Water Act citizen lawsuit. With the recent filing of a Motion for Summary Judgment (MSJ), the lawsuit is now at a point where the plaintiffs and ACT can make a statement, with facts, to dispute the many misstatements on Perdue’s savefarmfamilies.org website.

In an interesting turn of events, the Governor of Maryland attempted to interfere with an on-going litigation by writing this letter to Dean Haddon of the University of Maryland School of Law, which was promptly replied to in a terse response to Gov. Martin O'Malley. On Nov. 21, various Waterkeepers of the Chesapeake also responded to O'Malley's letter with their statement.
