In some ways, this is analogous to thunderstorms on a hot, humid day, when there just needs to be a trigger to get the process going. The Virginia Department of Health (VDH) and the Virginia Harmful Algal Bloom Task Force, which includes the VDH, the Virginia Department of Environmental Quality, and the Old Dominion University Phytoplankton Laboratory, will continue to monitor water quality in the lake. Although some blooms occur naturally, their numbers have increased nationwide over the past 40 years.

The environmental conditions that support golden alga are broad, and little is known about the specific and complex conditions that allow it to gain a competitive edge over other species, or about what causes a bloom that results in fish kills. Basin 1 is fed by a watershed covering 113 square miles and basin 2 is fed by a watershed covering only 33 square miles. Please do not call this number for map or status updates. Note: Although ponds and lakes smaller than a few hundred surface acres can be treated successfully, these treatments may not be economical or feasible in the larger and more complex reservoirs and rivers.

Most fish kills, however, do not continually affect the entire lake and different parts of the lake may continue to support excellent fishing. We still have the nutrients coming into the water body, and we need to determine potential sources if possible as well as compensating for what is occurring naturally from wildlife and natural foliage decomposition, Rigdon said. When the first outbreak was discovered in summer 2018, the primary areas impacted were upstream in Lake Anna, except for an anomaly at one downstream area, Fishermans Cove in Spotsylvania County near the dam.
