The US Army Corps of Engineers dammed the Roanoke River, with construction starting in 1947 and finishing in 1952. The new reservoir was justified primarily by flood control and hydropower generation benefits.
The reservoir has become a major recreational attraction as well, increasing tourism to Mecklenburg County and Clarksville in particular. Large motorboats are a common sight on US 58 now.1
The Bugg's Island Project ended up being renamed in 1952 after a North Carolina member of the US House of Representatives, John H. Kerr. He was instrumental in getting the project authorized in 1944 as part of the Pick-Sloan Flood Control Act.
A decade earlier, the Corps of Engineers had not advocated for funding the 17 possible projects which it had identified in the Roanoke River watershed. The Federal agency had determined that costs exceeded benefits, and elected officials in the US Congress from Virginia were not champions of increasing the costs of the Federal government.
A major flood in August, 1940 devastated farmers and industry in the Roanoke River valley. That shifted opinions, and after restudying the watershed the Corps recommended 11 projects. It ended up getting funding to build two. Philpott Dam was completed on the Smith River, an upstream tributary of the Roanoke River. Kerr Dam was built across the main stem of the Roanoke River, just upstream from Buggs Island.
For over 50 years, Virginia officially referred to Buggs Island Lake rather than Kerr Reservoir. In 2015, Mecklenburg County officials convinced the state to use "Kerr" in marketing materials in order to increase tourism.1
