Rathbun Lake State Park features a large reservoir formed by the Rathbun Dam, offering extensive opportunities for boating, fishing, hiking, and camping in a scenic southern Iowa setting.
Rathbun Lake State Park is located in southern Iowa near the Missouri border and centers around Rathbun Lake, a reservoir created by the U.S. Army Corps of Engineers' Rathbun Dam on the Chariton River. The park lies within the rolling hills and wooded landscapes of Appanoose County, offering a mix of hardwood forests, prairie remnants, and wetland habitats. Rathbun Lake covers approximately 11,000 acres, making it one of Iowa’s largest reservoirs and a key resource for flood control, water supply, and recreation. The park provides extensive recreational activities including boating, kayaking, fishing, hiking, mountain biking, and camping. Anglers come for species such as largemouth bass, crappie, catfish, and walleye, while paddlers enjoy calm coves and open water. Trails wind through forested areas and along scenic bluffs overlooking the lake. Rathbun Lake State Park also features several developed campgrounds and cabins, playgrounds, picnic areas, and a modern marina. The lake and surrounding parklands support a variety of wildlife including white-tailed deer, wild turkeys, bald eagles, and a diversity of songbirds, making it a popular destination for wildlife viewing and birdwatching. Historically, the creation of Rathbun Lake in the 1960s was a major project to aid in flood control, water supply, and recreation development, contributing to regional tourism and outdoor culture. Its combination of water-based activities, forested landscapes, and quiet natural settings makes it a prominent outdoor destination in Iowa, appealing to families, anglers, and outdoor enthusiasts seeking a multi-use recreational area.
