Lake Anna is one of the largest freshwater inland reservoirs in Virginia, covering an area of 13,000 acres (53 km2), and located 72 miles (116 km) south of Washington, D.C. in Louisa and Spotsylvania counties (and partially in Orange County at the northern tips). The lake is easily accessible from Richmond and Charlottesville, and is one of the most popular recreational lakes in the state.

HistoryEdit
The reservoir is formed by the North Anna Dam on the North Anna River at 38°00?47?N 77°42?46?W. In 1968, Virginia Electric and Power Company (now Dominion) purchased 18,000 acres (73 km2) of farmlands in three counties along the North Anna and Pamunkey rivers to provide clean, fresh water to cool the nuclear power generating plants at the North Anna Nuclear Generating Station adjacent to the lake. By 1972 the lake bottom was cleared of all timber and the dam was nearing completion. It was projected to take three years to completely fill the lake, but with the additional rainfall from Hurricane Agnes, the lake was full in only 18 months. The first communities broke ground at about that same time and now some 120 different communities dot the shores of the lake. In March 1986, construction on the dam's nuclear power plant began and the two reactors went into commercial operation in December 1987.

DescriptionEdit
Lake Anna is approximately 17 miles (27 km) long from tip to tip, with 200 miles (320 km) of shoreline. The lake is divided into two sides: the public side (also known as the "cold" side) and the private side (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.
Preliminary steps toward the addition of a third reactor have raised protests from environmentalists and property owners, who fear an increase in the water temperature and a decrease in the water level, particularly on the private side. According to Dominion, the water discharged from the plant is usually about 14 °F (7.8 °C) warmer than the intake water.
North Anna DamEdit
The dam creating the lake, North Anna Dam, is a 5,000-foot-long (1,524 m) and 90-foot-high (27 m) earthen embankment dam. It is 30 feet (9 m) wide at its crest which sits at an elevation of 265 feet (81 m) above sea level. The dam's spillway is located in the center of its body and is 200 feet (61 m) wide, containing three main 40-foot-wide (12 m) and 30-foot-high (9 m) radial gates. Two smaller 8.5-foot (3 m) wide and tall gates on the outer edges of the spillway section maintain normal discharges. Normal elevation for the reservoir is 250 feet (76 m). The dam's hydroelectric power plant is located on the west side of the spillway and is supplied with water via a 5-foot-diameter (2 m) penstock. The plant consists of two small open runner turbine-generators, the larger with a 775 kW capacity and the smaller rated at 225 kW for a combined installed capacity of 1 megawatt.
Use and recreationEdit
The lake has gained in popularity in recent years as a vacation destination and has seen a corresponding rise in retirement and second homes. The manmade lake offers swimming, sailing, boating, fishing, and a range of sponsored events.
Attractions in the lake's vicinity include vineyards, antique shopping, golf, historic sites, theme parks, and hiking trails. Power boating and sailing are popular among lake visitors and residents, with launching facilities, boats and personal water craft available for rent at several marinas. Sailboating is most popular on the wider southern end of the lake; while water sports enthusiasts tend to congregate in the mid-lake area; and fishermen favor the northern "on Golden Pond" end, fishing for more than 30 species including largemouth bass, striped bass, walleye, catfish, crappie, bluegill, white perch and yellow perch. The lake is served by a number of fishing guide services, and sanctioned tournaments attract competitive fishermen from across the state and mid-Atlantic area.
Lake Anna State Park, offering picnic areas and boat launching ramps, is located directly on the lake's public side eastern shore. The park has a maintained beach area with snack bar, docks, an exhibit center and several miles of hiking, horse trails and tours including visits to the remains of Goodwin gold mine and gold panning. The state park offers rental cabins for overnight lodging.
EventsEdit
Lake Anna is the site of several major water-related events including:
Rumpus in Bumpass, an annual spring triathlon festival, with an International/Olympic-distance race and a sprint-distance race held on consecutive days.
The Kinetic Race weekend in May with a half-distance race on Saturday and a sprint-distance race on Sunday
The Giant Acorn triathlon weekend in the fall, featuring an International/Olympic-distance triathlon followed by a sprint-distance triathlon on the next day.
