Caesar Creek State Park is a public recreation area located in southwestern Ohio, five miles (8 km) east of Waynesville, in Warren, Clinton, and Greene counties. The park is leased by the State from the U.S. Army Corps of Engineers, who in the 1970s erected a dam on Caesar Creek to impound a 2830acres lake. The total park area, including the lake, is 7530acres.
Fossil collection is allowed at Caesar Creek State Park with the following restrictions: No tools allowed, no fossil collecting for commercial use, all fossils kept must fit in the palm of your hand, and all fossil collection must take place in the designated fossil collection zone.[1]
The dam is an earth and rock fill dam high and long. The Army Corps site is an area of . The watershed above the dam has an area of 237sqmi. Construction started in 1971 and was finished in 1978.
The Army Corps site states:
"Congress authorized Caesar Creek Lake under the Flood Control Act of 1938. The Louisville District of the U.S. Army Corps of Engineers designed, built, and operates Caesar Creek Lake.
"During the fall and winter months, the lake level is lowered to prepare for the storage of heavy spring rainfall. If heavy rains occur, surface water runoff is stored in the lake until the swollen streams and rivers below the dam have receded. Once they can handle the discharge of the stored water without damage to lives or property, the extra water is released."
The site is in the Warren County townships of Massie and Wayne.
The construction of the Caesar Creek Lake flooded the small farming village of New Burlington, Ohio in 1978. The history of the community was collected through stories, letters, and journals in the book New Burlington: The Life and Death of an American Village by John Baskin.
