William H Harsha Lake Dam

US Army Corps of Engineers campground, 2 sites

Overview

William H. Harsha Lake was authorized under the Flood Control Act of 1938. The Louisville District of the U.S. Army Corps of Engineers designed, built, and operates the project to reduce flood damages downstream from the dam, which is located roughly four miles south of Batavia, Ohio, on the East Fork of the Little Miami River. 

Construction began in May 1970 and the lake became fully operational in May 1978. Since its completion, William H. Harsha Lake has prevented more than $87 million in flood damages. 

Originally called East Fork Lake because of its location, the lake was renamed in 1981 to honor retired congressman William H. Harsha.

Natural Features

In 1869, there were two gold mines within what is now the William H. Harsha Lake project boundaries. One, located on the north bank in the vicinity of Elk Lick Road, consisted of a flume for washing glacial deposits. The other was a tunnel mine in the vicinity of Twin Bridges Road. Both are now under water.
