Lake Anna Cyanobacteria Mitigation Program to Begin this Month

The Lake Anna Civic Association would like to make Orange County residents aware of an upcoming Cyanobacteria Mitigation Program intended to reduce Virginia Department of Health Recreational Advisories, also known as No-Swim Advisories, related to harmful algae blooms in Lake Anna Areas of Interest (AOIs). 

Over the next several months, specific AOIs within Lake Anna will receive applications of a United States Environmental Protection Agency (EPA) and Virginia Department of Agriculture and Consumer Services (VDACS) approved product, known as Lake Guard Oxy. The goal of this treatment is to be preventative against the development of harmful algae blooms. 

The first application in this pilot program will target the Pamunkey AOI, a section of Lake Anna which borders Orange County, during a planned timeframe of June 16 - 17, 2022.
