About Lake Wilhelm

Lake Wilhelm holds spot 5 on the LakePA 100. It is a 1,680-acre reservoir in Mercer County, part of the Northwest region. That acreage is the figure given by DCNR's Where to Boat table. At a thousand acres or more it is Big Water, so plan for wind and long crossings. Motorboats with a capped motor size use it too, so expect to share the water. That rule is as listed by the county boating rules in 58 Pa. Code § 111.43. There are nine put-ins on our list for this lake, among them Lake Wilhelm - Old Launch #1, Lake Wilhelm Launch #1 and Lake Wilhelm Launch #2. Lake Wilhelm - Old Launch #1 has a launch ramp and parking listed as 10 spaces or more. At Fish and Boat Commission and state park launches your boat needs a Pennsylvania registration or a PFBC or State Parks launch permit. It is held back by a dam: stay well clear of the dam, the spillway and the outlet structures. It counts toward the Northwest region milestone. In a straight line, it is about 34 miles from Youngstown to the nearest put-in. Before you go, check posted signs, the weather and the operator's notices.

Paddling has real risks. Wear your life jacket. Pennsylvania requires it to be worn on canoes, kayaks and paddleboards from Nov 1 through Apr 30, and by children 12 and under all year. Check the weather, posted signs and the operator's notices before you launch. Stay well away from dams, spillways and outlet structures. You paddle at your own risk.
