Description
Rathbun Lake was constructed and is operated by the U.S. Army Corps of Engineers. Located at Chariton River mile marker 142, approximately 7 miles (11 km) north of Centerville, Iowa, in Appanoose County, it is one of the largest lakes in Iowa. The lake was constructed to control flooding, provide recreation opportunities, abate stream pollution, fish and wildlife enhancement, and maintain minimum stream flow on the Chariton, Missouri, and Mississippi Rivers. The Chariton and South Fork of the Chariton River are the major sources of water flowing into Rathbun Lake.
