Construction of the Mount Morris Dam, at the north end of the park, was begun in 1948 by the United States Army Corps of Engineers under the Flood Control Act of 1944, and completed in 1954. The Genesee River became wider and deeper immediately upstream as a result, but areas downstream were spared yearly flooding which destroyed valuable farmland.
