The Commonwealth of Pennsylvania, acting by and through the Pennsylvania Fish and Boat Commission, owns and controls about 138 acres at this site, which includes the 76 acre lake, dam, shoreline and associated lands. The Commonwealth acquired this property in 1957. The dam, known locally as the Alcoa Dam, was built in 1943.

Canonsburg Lake is designated as an Approved Trout Waters Open to Year-Round Fishing. For all other species of fish the lake is managed under statewide regulations for Commonwealth Inland Waters. Shore fishing is permitted.

BOATING

Boating at Canonsburg Lake is limited to boats powered by electric motors and un-powered boats. The primary type of boats used on the lake are shallow-draft, lightweight fishing boats, canoes and inflatables. A surfaced launch ramp is available along with a parking lot that can accommodate at least 10 vehicles.

Un-powered boats may be moored at the lake in accordance with Commission property regulations. To be used at the lake, boats must be registered or have a valid launch permit (permits are issued by the Commission or PA Dept. of Conservation and Natural Resources).
