Submit reports to VDH using the online reporting form within 24-48 hours of the algae bloom condition. Sometimes algae rapidly grow out of control, or bloom. One of the primary research focus areas in the SOLitude assessment was the availability of nutrients, primarily phosphorous, in the water column (dissolved phosphorous) and in sediment. These blooms are known as harmful algal blooms or HABs. This is a complex problem and the approaches to remedy the problem are numerous, varied, expensive, and primarily long-term before effects are realized. DEQ and VDH received $3.5 million in the biennial budget to study harmful algal blooms in Lake Anna and the Shenandoah River, which feeds water to the Chesapeake Bay. That is why the FY23 Virginia State Budget included 1 million dollars of funding for a study on how to mitigate algal bloom issues on Lake Anna. The term alga is used when only one species is being referenced, such as Prymnesium parvum, the golden alga. The SOLitude report on spot algaecide treatments provides additional justification for LACAs focus on mitigation efforts that can be implemented now with funding levels that LACA can reasonably raise through donations and grants.

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. Operate boats in a manner that doesnt unnecessarily stir up the lake bottom or erode shorelines where nutrients tend to concentrate. Worldwide scientific literature states that golden alga is not toxic at 86 degrees Fahrenheit or above. The alga is a rapid growing and resilient algae species, out-competing other algae for nutrients and thriving in a wide variety of environmental conditions. SOLitudes data for basin 2 indicated that the lake was stratified and lacked oxygen over the sediments throughout the 2021 algae growing season.
