One of the findings from a 2022 study of the upper North Anna River is that Phosphorus is a major source and contributor to the HAB issues we experience here at the lake.
Total Phosphorus data from LACA and DEQ sampling since 2005 indicate that the upper areas of the lake are eutrophic (“sick”). Levels of phosphorus, nitrogen, and chlorophyll exceed well established thresholds for eutrophic conditions in all three major tributaries.
Fortunately, there are multiple ways that the natural phosphorus cycle can be accelerated. LACA developed a program concept that incorporates modern, well-understood technologies to remediate Phosphorus in the upper areas of the lake. You can review LACA's concept by clicking on the cover slide below. This presentation was submitted to the Lake Anna Advisory Committee (LAAC) at their November 2023 meeting in Louisa.
LACA's WQ Volunteers
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. LACA's cyanobacteria sampling data and maps can be found at this link. LACA's data and information on our Cyanobacteria Mitigation & Remediation Program is available at this link.
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.

With the turn of the calendar it's time to start thinking about summer and all the fun Lake Anna brings. One of those long-standing traditions is the annual fireworks show, which will be held on Saturday, July 1 to celebrate the 4th of July holiday.

Our donors are listed here starting with those received August 1 of each year through July 31 of the following year.
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.
