Rathbun Lake - Our Home Port
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 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.
The construction of Rathbun Dam and Reservoir was authorized by the Flood Control Act of 1954 (Public Law 83-780). Construction of the dam and embankment began in September 1964. The lake's surface area is 11,000 acres at normal pool level and 21,000 acres at maximum level. Normal surface elevation is 904 feet above sea level. The dam itself is rolled earthfill construction and is 10,129 feet long, 30 feet wide at the top, and rises 100 feet above the streambed. Operation as a multi-purpose unit began November 1969 and the top of multi-purpose pool (904 msl) was reached on October 10, 1970. Rathbun Lake was dedicated July 31, 1971 with President Richard Nixon being the keynote speaker.
Camping, sightseeing, fishing, boating, picnicking and hunting are favorite activities on and near Rathbun Lake. The lake’s fish and wildlife resources provide sightseers, fisherman, and hunters ample opportunities for their sports. Bald eagles, white-tailed deer, Canada geese, wild turkey, crappie, walleye, channel catfish and other wildlife can be found at Rathbun Lake.
Rathbun Lake has much to offer both sailors and power boaters. With a nine mile fetch of open water on the main body of the lake, the size of the lake combined with the prevailing winds make Rathbun Lake one of the best sailing lakes in Iowa. And both sailors and power boaters find the lake's numerous coves ideal for anchoring out. Water skiing and fishing are also very popular on the lake. Rathbun Lake has two marinas offering a full line of marina services.
Eight parks have been developed for public recreation. Six are managed by the Corps of Engineers, and one state park is managed by the Iowa Department of Natural Resources. Recreation facilities include boat ramps, courtesy docks, campgrounds, picnic areas and playgrounds. Honey Creek State Park Resort opened in 2008 and is Iowa's first-ever state-run resort with more than a hundred guest rooms, an 18-hole golf course, and an indoor water park.
