Canonsburg Lake

Canonsburg Lake is a lake in Canonsburg, Pennsylvania. It is an artificial lake formed by the waters of Little Chartiers Creek behind a 525 feet long and 45 feet high concrete dam. The dam was built in 1943 by Alcoa to create a freshwater reservoir for the Canonsburg Forging Plant, which was considered a strategic resource during World War II. In 1957, the Pennsylvania Fish and Boat Commission acquired the 138-acre property from Alcoa, which included the 76-acre surface area of the lake plus the dam and surrounding lands. The PFBC converted the body of water from an industrial reservoir into a recreational lake.
