Struble Lake has a number of warmwater/coolwater species, with good to excellent fishing for walleye, channel catfish and black crappie. All species of fish are managed under Commonwealth Inland Waters regulations. Shore fishing is permitted.
Fish habitat structures have been placed in the lake over the years as part of the Commission's Cooperative Fish Habitat Improvement Program.
Boating at Struble Lake is limited to boats powered by electric motors and un-powered boats. The primary type of boats used on the lake are moderate-draft fishing boats, sailboats and recreational runabouts.
A surfaced launch ramp and loading dock is available. There is a gravel parking lot that can accommodate at least 10 vehicles, and some limited lakeside parking.
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).
