HistoryThe reservoir is formed by a dam on the North Anna River. 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 11 months. The first communities broke ground at about that same time and now some 120 different communities dot the shores of the lake. In 2010, a tragic boating accident occured on the lake, killing a Spotsylvania County Sheriff's deputy.
DescriptionLake Anna is approximately 17 miles (27 km) long from tip to tip, with some 200 miles (300 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 degrees warmer than the intake water.
Use and recreationsailing, boating, world-class fishing, and multiple annual triathlons. Surrounding attractions include vineyards, antique shopping, golf, historic sites, theme parks, and hiking. To get the most out of the lake, one can rent a boat from various local marinas and businesses. Sailboat enthusiasts will prefer the more open, wide water appeal of the southern end of the lake, although the lake's several bridges, including the main 208 bridge, are too low for a sailboat to pass beneath. Water sports junkies tend to enjoy the mid-lake area, while the fishing crowd has lots of hot spots in nooks and crannies of the northern "on Golden pond" end. Anglers fish for over 30 species including largemouth bass, striped bass, walleye, catfish, crappie, bluegill, white perch and yellow perch. Weekly fishing leagues keep local residents happy, while sanctioned tournaments bring fishermen and women from afar.
Lake Anna State Park, complete with picnic areas and boat launching ramps, is located directly on the lake on the public side, making it available to everyone. The park also has a beach area with snack bar, docks, an exhibit center showing how the lake was created, and miles of hiking and horse trails. One can tour the remains of Goodwin gold mine and pan for gold. The original plantation house still stands in ruins and a hiking trail leads to it. The state park offers rental cabins for overnight lodging. Visitors also can stay at waterfront hotels, or in any of dozens of available vacation rental waterfront homes.
Triathlon festivalsLake Anna is the site of Rumpus in Bumpass, an annual spring triathlon festival, with an International/Olympic-distance race and a sprint-distance race held on consecutive days.
The lake also hosts the Giant Acorn triathlon weekend in the fall. This weekend also features an International/Olympic-distance triathlon followed by a sprint-distance triathlon on the next day.
