Who Built Lake Anna and How Did They Fill It?

Lake Anna, one of the largest freshwater inland reservoirs in Virginia, is a beacon of recreation and natural beauty. Its shimmering waters and scenic surroundings captivate both residents and tourists. But behind this serene facade lies a tale of engineering marvel, strategic planning, and environmental considerations. This article delves deep into the origins, construction, and legacy of Lake Anna, a gem in Virginia’s tourism landscape.

The Story of Lake Anna

The story of Lake Anna is intertwined with Virginia’s quest for sustainable energy. In the late 1960s and early 1970s, as the demand for electricity grew, Virginia’s power companies sought ways to meet this demand while ensuring environmental sustainability. Dominion Power, now known as Dominion Energy, envisioned a nuclear power plant. But such a plant would require vast amounts of water for cooling. Thus, the idea of Lake Anna was born: a reservoir that would serve the dual purpose of cooling the power plant and providing recreational opportunities for Virginians, much like other commercial nuclear power plants in the US.

Who Built Lake Anna?

Dominion Power took the helm in the construction of Lake Anna. Collaborating with engineers, environmentalists, and local communities, the company embarked on what would become one of Virginia’s most significant infrastructure projects. The goal was clear: create a reservoir that would be both functional for the power plant and beneficial for the community, a challenge faced by many utility industry projects.

Choosing the Location

Selecting the perfect location for Lake Anna was a task that required meticulous planning. The site had to be proximate to the power station, possess the right topography for a reservoir, and be environmentally viable. After extensive surveys, consultations with the U.S. Geological Survey, and numerous feasibility studies, the current location was chosen. This area, primarily a mix of farmland and forests, would soon transform into a bustling hub of activity, a trend seen in many environmental conservation projects.

The Construction Process

Constructing Lake Anna was an engineering challenge. The first step was building the dam, a structure that would hold the waters of the North Anna River, turning the river’s course into a vast reservoir. The dam, named the “North Anna Dam,” was a marvel of its time. Built with earth, rock, and other aggregates, it stands as a testament to human ingenuity and the advancements in civil engineering.

Environmental considerations were paramount. Dominion Power, in collaboration with agencies like the Environmental Protection Agency (EPA), ensured that the construction had minimal adverse effects on the local ecosystem. Measures were taken to protect local flora and fauna, relocate affected families, and ensure the sustainable use of resources.

Filling the Lake

With the dam in place, the next challenge was filling the reservoir. This wasn’t as simple as waiting for the river to do its job. Strategic planning was essential to ensure the lake filled at the right pace, maintained the required water quality, and established a balanced ecosystem. The primary source of water was the North Anna River. The formation of the lake was achieved by constructing a dam, standing at 90 feet high and made of earth and rock, on the North Anna River close to Bumpass. Engineers meticulously planned for the emergence of the 17-mile long Lake Anna to the west of the dam, anticipating its creation after approximately two years of consistent rainfall and runoff.

Lake Anna Today

Today, Lake Anna is a jewel in Virginia’s crown. Spanning over 13,000 acres with a shoreline that stretches for more than 200 miles, it’s a haven for nature lovers, anglers, boaters, and families looking for a lakeside retreat. The lake’s waters are divided into two parts: the “public side,” open for all forms of recreation, and the “private side” or “hot side,” which receives warm water discharged from the power station and is limited to property owners. This division ensures both recreational safety and optimal operation of the North Anna Nuclear Power Generating Station.

Environmental and Economic Impact

Lake Anna’s creation was not just an engineering success; it was an environmental and economic triumph. The lake has become a sanctuary for various species, with concerted efforts from organizations like the National Wildlife Federation ensuring it remains a vibrant ecosystem. Economically, the lake has transformed the region. Tourism has boomed, with visitors flocking to enjoy the lake’s recreational offerings. The real estate market has seen a surge, with properties around the lake being highly sought after. Companies like Spear Builders of Virginia have capitalized on this demand, offering custom home building and construction services for those desiring a lakeside residence, a trend seen in many real estate markets near popular tourist destinations.

Lake Anna’s story is one of vision, collaboration, and dedication. From its inception as a coolant reservoir to its current status as a recreational and ecological paradise, the lake stands as a testament to what can be achieved when human ingenuity aligns with nature.
