East Fork Wildlife Area is located in southwestern Ohio, on the southeast edge of Williamsburg. Access to the north side of the lake is from State Route 32 between Batavia and Williamsburg. Access to the south side is from State Route 125 near Bantam. The wildlife area may be reached from roads off State Route 133, east of the area, and Old State Route 32 west of Williamsburg. The 2,705-acre wildlife area lies at the northeast edge of William H. Harsha (East Fork) Lake, where the east fork of the Little Miami River flows into the lake. The lake was constructed by the U.S. Army Corps of Engineers for flood control, water supply storage, water quality control, and recreation. In summer the lake is normally 2,160 acres. During periods of heavy rainfall, the lake covers portions of the normally dry wildlife area. East Fork State Park lies south and west of the wildlife area on both sides of William H. Harsha (East Fork) Lake. Meadow and grain crops make up about 25 percent of the wildlife area; about 45 percent is woodland and 30 percent is reverting fields of shrubs, small trees, grasses, and forbs. The wildlife area varies from level upland and bottomland fields to gently rolling and steep wooded and reverting hillsides.
