The Kokosing Lake Wildlife Area is in Knox County, 1.5 miles northwest of Fredericktown and five miles northeast of Chesterville. The area can be reached by traveling two miles northwest of Fredericktown on Waterford Road (CR 6). It is part of the North Branch of Kokosing Lake flood control project of the U.S. Army Corps of Engineers. Approximately 1,113-acres are managed by the Division of Wildlife for fish and wildlife, including a 160-acre lake. Limited camping and picnicking are provided by the U.S. Army Corps of Engineers.
The dam and the camping and picnic facilities are in the southwest corner of the area north of County Road 6. There is a five-acre island in the south end of the lake. A 1.5-acre pond lies in the northeast corner of the area along with four acres of marsh.
A large woodlot consisting mainly of pin oak and hickory is located on the south end of the lake, east of the North Branch Kokosing River. Several small streams flow into the area from the north and west.
