Located in the heart of Ohio’s agricultural country of Pickaway and Fayette Counties, Deer Creek State Park is central Ohio’s vacation showplace. A collage of meadows and woodlands surround the scenic reservoir. This 2,337-acre resort park features a modern lodge, cottages, campground, golf course, swimming beach and boating for outdoor enthusiasts.Deer Creek State Park lies near the eastern edge of the great till plains of Ohio. These plains receive their name from the glacial debris, or till, which is a mixture of clay, sand, silt and gravel that was deposited by the glaciers. As glaciers advanced across the northern two-thirds of Ohio, most hills and valleys were covered and filled in by the till, leaving this part of Ohio relatively flat.
