Cecil M. Harden Lake, commonly known as Raccoon Lake, is a 2,060-acre U.S. Army Corps of Engineers flood control impoundment located approximately 7 miles east of Rockville in west-central Indiana. Built between 1956 and 1960 on Big Raccoon Creek, 33 miles upstream from its junction with the Wabash River, this reservoir operates under a cooperative management agreement between the Corps of Engineers and the Indiana Department of Natural Resources. The lake averages 24 feet deep at summer pool but undergoes a substantial 22-foot drawdown each fall, exposing significant portions of the reservoir during winter months. The surrounding property encompasses 2,005 acres of land featuring diverse tree species, wildflowers, berries, and mushrooms. Native forest and large rock outcrops characterize the upper section of Big Raccoon Creek. The rolling farmland setting and proximity to the historic Parke County Covered Bridge Festival make this a popular destination for both fishing and recreation.
