A float plane hanger with a pleasure boat in the foreground on the lake at Lake Anna, Virginia. Lake Anna at approximately 13,000 acres, is a popular spot for fishing and boating, located in quite rural Virginia. The lake was created in 1972 by Virginia Power in order to supply ample amounts of cooling water to its North Anna Nuclear Power Station. To do this Virginia Power cleared the lake bottom and also constructed a 90-foot high dam. Having three dikes, it also separates the lake into two sections. The larger section, commonly referred to as the “cool side” consists of 9,600 acres. The other section is called the “warm side”, and is 3,400 acres. The power station draws water from the “cool side” and then releases water several degrees warmer into the other portion of the lake, hence the name “warm side”. At the third dike, water from the warm side empties back into the larger side of the lake and passes over the dam, starting the cycle again.
