About East Fork State Park

A 2,107-acre reservoir called William H. Harsha Lake forms the center of this 4,870-acre recreation area along the East Fork of the Little Miami River. The lake, created in 1978, sits behind a large earthen dam with smaller saddle dams managed by the U.S. Army Corps of Engineers. A 33-mile perimeter route known as the Steve Newman World-Walker Trail circles the property, and the park has hosted junior and collegiate rowing events, including the US Rowing Youth National Championships.

Hours, fees, camping, reservations and closures are set by the park and change often. Check the official park site before you go.
