The different degrees in the Lake Anna water temperature is one of the many ways the lake is fantastically interesting and different from other lakes! The warmer temperatures on “the warm side” of Lake Anna significantly extend the water sports season into the fall and winter months. The Lake Anna water temperatures fluctuate throughout the lake (and throughout the year) due to the support role Lake Anna plays with the power plant.
Lake Anna stretches into 3 counties of Virginia: Louisa county, Spotsylvania county, and Orange County (partially at the northern tips). As one of the best recreational lakes in the state, it is also one of the largest.

Lake Anna Water Temperature History
Lake Anna was built in the early 1970s to support the operation of North Anna Power Station. The water at Lake Anna moves through an important cycle to help the power plant function. When it was built, Lake Anna was divided into two completely separate bodies of water, commonly called “the cold side” (aka the public side of Lake Anna) and “the warm side” (aka the private side of Lake Anna).
The cooler water on the cold side of Lake Anna is pumped into the power plant to absorb heat inside the plant. When the water is inside the power plant, the water temperature increases. Next, the water is pumped out of the power plant into the warm side of Lake Anna, which acts as a “cooling pond” where the water sits and the temperature cools down. After the water cools down on the warm side, the discharged water is then pumped back to the cold side of Lake Anna to begin the cycle again. The power station pumps an impressive 2 million gallons of water per minute!
