Carvins Cove History

Updated on 08/01/2016 1:08 PM

Take a photographic tour of the construction of the Carvins Cove dam and reservoir.

Construction on the 80-foot tall dam was started in the spring of 1927 and substantially completed in January 1928. However, due to droughts and financial hardships, the project sat idle for many years. In 1938, the City of Roanoke condemned the project and completed final work on the reservoir and dam. The reservoir reached full pond in 1946.
