Lake Anna is a 13,000 acre reservoir in the rolling fields and forested triangle formed by the cities of Charlottesville, Fredericksburg, and Richmond, Virginia. The lake was created by Virginia Electric and Power Company, now Dominion Energy, Inc., in 1972 to serve as a recreational lake and provide cooling water for the North Anna Power Station.


Virginia Department of Health announced a No Swim Advisory for the upper part of Lake Anna on July 22, 2020.

On July 15, 2020, DEQ and VDH tested 10 sites on Lake Anna. On 3 sites, cyanobacteria counts were above 100,000 cells/ml. Of the 10 sites, there were detectable levels of the cyanobacteria toxins at 6 if those site, but all 6 were below safe swimming levels. There were no areas on the lake that measured above the unsafe toxin levels.

Water Quality

The first lab results are in and Lake Anna looks good. LACA's Water Quality (WQ) team and Virginia's DEQ have taken water samples from the lake and streams in the watershed. The results can be seen in the WQ Data pages.

The algae testing by LACA's WQ team began in early May and will continue through early November.  The results can be found in the WQ Data pages.

Environmental Preservation 

An expansion of the former LACA Environmental Education Committee, the Environmental Preservation Committee has turned its focus on the causes of the recent Harmful Algae Blooms, potential remediation and possible solutions to the issue.  As a result they are also looking at other detrimental impacts to the beauty and enjoyment of Lake Anna.

Emergency Services & Safety

As the summer boating season begins, there are numerous things you should check before heading out on the lake.  In addition to ensuring your boat is in good operating condition, you should make sure you have all the necessary safety equipment on board.  There are other tips to keep you and your passengers and others safe.

The committee also encourages everyone to be aware of your surroundings and know the various 911 emergency markings such as the bridge signs, yellow dock signs and island signs.

Land Use

Great news! Louisa County has approved the creation of a new EMS station at Lake Anna on Rt. 208 near the Food Lion. Construction on New Bridge EMS can begin this year if the Lake Anna community raises $100,000 in “seed money” toward the $800,000 cost. The Foundation for Lake Anna Emergency Services has been established for the purpose of raising these funds.  Click here to learn more or to donate.

The Land Use Committee’s task is to review new developments to ensure that they meet LACA's goals on waterfront development and environmental aspects of all developments. To learn more click here.
