Rathbun Lake, Iowa, USA
Also known as: Lake Rathbun
One of the largest lakes in the state of Iowa, Rathbun Lake is located in Appanoose County and is a perfect place to enjoy water sports, fishing, and outdoor activities of all kinds. This beautiful lake in south-central Iowa has not always existed, though; it is a man-made reservoir, constructed in the 1960’s for drinking water supply, recreation, fish and wildlife habitat, flood damage reduction, downstream water quality improvement, and storage for supplementing navigational flows.
The U.S. Army Corps of Engineers built a dam spanning the Chariton River to create a reservoir for flood control, recreation, and a variety of other purposes – and thus, Rathbun Lake was formed. The lake is expansive, covering an area of 11,000 acres, and is popular for recreation. Due to nutrient and sediment runoff, Rathbun Lake is on Iowa’s list of impaired waters. However, organizations such as the Rathbun Land and Water Alliance have been formed to improve water quality and prevent runoff problems.
There are lots of ways to have fun on Rathbun Lake. Fishing, of course, is always popular, and anglers of all ages will enjoy relaxing in a boat as they reel in fish of various species. Some of the common fish in Rathbun Lake are crappie, walleye, channel catfish, and largemouth bass. Rathbun Lake has the largest warm-water fish hatchery in the state, and the hatchery produces a variety of fish such as channel catfish, walleye, saugeye, and largemouth bass. The hatchery is located below the dam, and interested visitors are free to take a self-guided tour of the operation.
