Some great pictures from our community and Lake Anna background:
Lake Anna is one of the largest freshwater inland reservoirs in Virginia, covering an area of 13,000 acres, and located 72 miles south of Washington, D.C., in Louisa and Spotsylvania counties (and partially in Orange County at the northern tip). The lake is easily accessible from Fredericksburg, Richmond, Charlottesville, Northern Virginia, and Washington, D.C., and is one of the most popular recreational lakes in the state.
Lake Anna is approximately 17 miles long from tip to tip, with 200 miles of shoreline. The lake is divided into two sides: the public side (also known as the "cold" side) and the private side, working as a cooling pond (also known as the "hot" side).
The public side is roughly 9,000 acres, while the private side is roughly 4,000 acres. The private side is formed of three main bodies of water, connected by navigable canals. The public and private sides are divided by three stone dikes. The private side has no marinas or public access ramps; only property owners and North Anna Power Station employees have access to the waters on the private side. The public side has several marinas and boat launches, including a boat ramp at an adjacent state park. The public side sees significantly higher boat traffic compared to the private side, especially on summer weekends.
The public side is known as the "cold" side because it provides water to cool the generators at the power plant; the private or "hot" side receives warm water discharge from the power plant. The private side can be substantially warmer than the public side, especially near the discharge point, where it can be too hot for swimming. The private side has an extended water sports season. Some water circulates back out of the private side into the public side through underground channels; consequently, the public side is warmer in the southern area near the dam. In the winter, some fish migrate to these warmer waters.
