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.


Listen to LACA on SAM-FM talking about Lake Anna's HAB issues and what is being done to work the problem



Current HAB Status

Water Quality

LACA's Water Quality (WQ) team and Virginia's Department of Environmental Quality (DEQ) regularly monitor the lake and streams in the watershed.   DEQ monitors the lake on a monthly basis.  LACA monitors water quality parameters four times a year in April, June, August and October.  LACA also works with DEQ and the Virginia Department of Health (VDH) to monitor for harmful algae blooms.  Our algae and water quality data are available in the WQ Data pages.  Virginia Department of Health (VDH) HAB info is available here.  Information on LACA's Cyanobacteria Mitigation & Remediation Program is available at this link.


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

Hayden Property Rezoning Hearing ends in Denial of the requested Re-Zoning.

The BOS unanimously rejected the rezoning request. Many Supervisors spoke during the process and many repeated issues of it not being a good idea to put more homes on this end of Pamunkey creek where the water is shallow, the HAB issue is the worst on the lake, and the well water seems to be hard to maintain for those that currently live there.
