Burr Oak State Park is a public recreation area located four miles (6.4 km) northeast of Glouster in the U.S. state of Ohio. The park sits mostly in Morgan County, with part extending into Athens County. The state park is centered at Burr Oak Lake. The dam for the lake is federal property under the jurisdiction of the Army Corps of Engineers, and is named Tom Jenkins Dam. It was built in 1950 for flood control. The maximum depth of the lake is around thirty feet. The lake and park are named for the burr oak tree, a variety of oak.
