Public vs Private side of the Lake
Lake Anna is approximately 17 miles (27 km) long from tip to tip, with 200 miles (320 km) of shoreline.[2] 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 (36 km2), while the private side is roughly 4,000 acres (16 km2). 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 of the private side. The public side has several marinas and boat launches, including a boat ramp at the state park. The public side sees significantly higher boat traffic than 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.
