Efforts are underway to manage the blooms. They also stated that data from other lakes and areas with algal issues shows that the contributions from agriculture, forested areas, and septic systems are at least as great as urban and development impacts on a watershed. Increased water flow with cooling fall temperatures and more regular breezes will begin to break up the blooms, but reducing the nutrient pollution at the source is the first step in keeping the water cleaner. The lake, located about an hour northwest of Richmond, has been home to algae blooms that can cause rashes and gastrointestinal illness, particularly in the northern Pamunkey and North Anna branches in Orange, Louisa and Spotsylvania counties. Algae blooms may last for days or weeks. A key finding in the assessment is that 80% of the phosphorous loading in basin 1 is driven by external sources in the watershed while only 20% of the phosphorous available to the aquatic biomass comes from internal loading (phosphorous stored in sediment).
