Lake Anna, nestled in the heart of Virginia, is a picturesque reservoir known for its scenic beauty and the pivotal role it plays in powering the region. The lake’s history is closely intertwined with the construction of the Lake Anna Nuclear Power Plant, an engineering marvel that has transformed the landscape. This article delves into the captivating story behind the creation of Lake Anna, its layout, and the impact of the power plant on the surrounding community.

Lake Anna was formed in the 1970s as a result of the North Anna River being dammed. The lake covers an area of approximately 13,000 acres and stretches across three counties: Louisa, Spotsylvania, and Orange. The dam, aptly named the North Anna Dam, stands proudly, serving as a gateway to the lake. With its sprawling shoreline and crystal-clear waters, Lake Anna has become a popular destination for fishing, boating, and recreational activities.

The lake’s layout is divided into two sections: the public side and the private side. The public side offers recreational opportunities for visitors, including public beaches, marinas, and campgrounds. The private side is primarily reserved for property owners and offers a more secluded and tranquil experience. The combination of public and private areas ensures that Lake Anna caters to a diverse range of interests and preferences.

In the 1970s, the demand for electricity in Virginia began to surge. To meet this growing need, the Virginia Electric and Power Company (now known as Dominion Energy) proposed the construction of the Lake Anna Nuclear Power Plant. The project aimed to harness the energy potential of nuclear power to generate electricity for the region.

Construction of the power plant commenced in 1971 and was completed in 1978. The plant consists of two nuclear reactors, each with a capacity of generating over 900 megawatts of electricity. The Lake Anna Nuclear Power Plant was the first commercial nuclear power facility in Virginia and has since been a reliable source of clean energy for the region.

By 1972, all timber on the lake bottom had been cleared, and the construction of the dam was approaching its final stages. Initially, it was estimated that it would take three years to fill the lake completely. However, thanks to the additional rainfall brought by Hurricane Agnes, the lake reached its full capacity in a remarkable 18 months. This expedited timeline led to the emergence of the first communities around the lake, marking the beginning of what would eventually become approximately 120 distinct communities adorning its shores.

In June 1978, the inaugural reactor of the Lake Anna Nuclear Power Plant commenced its commercial operation, signifying a significant milestone in the region’s energy landscape. This technological marvel started generating electricity, serving the growing needs of the surrounding areas. Subsequently, in December 1980, the second reactor of the power plant went into operation, further reinforcing the plant’s contribution to the region’s power grid. The North Anna Dam, an earthen embankment dam, stretches 5,000 ft in length, stands 90 ft tall, and measures 30 ft wide at its crest, positioned 265 ft above sea level. Playing a crucial role in the operations of the North Anna Power Station, this dam facilitates the passage of cooling water to the station through its radial gates. Additionally, the dam houses a hydroelectric power plant on its western side, which receives water from a 5 ft diameter penstock. The power plant comprises two small open runner turbine-generators, one with a capacity of 775 kW and the other with a capacity of 225 kW, combining to produce a total of 1 megawatt of power. At the heart of the dam, the spillway spans 200 ft in width and features three primary radial gates, each measuring 40 ft wide and 30 ft high, regulating the normal discharge of water.

The impact of the power plant extended beyond energy production. During the construction phase, the local economy experienced a significant boost, creating job opportunities and driving economic growth. The presence of the power plant also necessitated the establishment of support infrastructure, including housing, schools, and healthcare facilities, further benefiting the surrounding communities.

Dominion Energy has been committed to ensuring the safety and environmental responsibility of the Lake Anna Nuclear Power Plant. Stringent measures are in place to prevent any adverse impact on the lake’s ecosystem. Regular monitoring of water quality, wildlife, and vegetation ensures the preservation of the area’s natural beauty.

Lake Anna serves as a cooling reservoir for the power plant, where warm water is released after the cooling process. This controlled release maintains a balanced temperature within the lake and fosters the growth of a diverse aquatic ecosystem. Fish stocking programs are also implemented to support the lake’s thriving fish populations. Embarking on the tranquil waters by kayak or boat offers a close-up encounter with the impressive dam, but there are also abundant locations where one can delve deep into the captivating history of both the dam and the lake. Begin at the North Anna Battlefield, the very site where it all originated, now transformed into a haven for visitors to explore scenic trails and gain insights into the events of the American Civil War. The creation of the dam gave rise to the Lake Anna reservoir and the Waste Heat Treatment Facility, both of which have evolved into beloved recreational destinations. Surrounding the lake are captivating history museums and archive centers, including the Louisa County Historical Society, Spotsylvania County Museum, and the Lake Anna Visitor Center. For a more immersive experience, venture to Lake Anna State Park, a historical gem boasting an abundance of hiking trails and idyllic camping opportunities.

Lake Anna stands as a testament to the harmonious coexistence of nature and technology. Its creation through the damming of the North Anna River has provided a source of recreation and leisure for visitors while simultaneously serving as a vital energy hub. The Lake Anna Nuclear Power Plant has not only met the region’s growing electricity demands but has also brought economic prosperity to the local communities.
