The Floyd River runs through Iowa and South Dakota, covering a length of 111 miles. It was named after Charles Floyd, a member of the Lewis and Clark Expedition who died near its banks in 1804. The river has experienced multiple flooding events over the years, causing significant damage to the surrounding areas. To prevent future flooding, several dams and reservoirs have been constructed, including the Union County Dam, the Akron Impoundment, and the Alcester Dam. These structures regulate water flow and provide a source of water for agriculture and recreation. The Floyd River basin is primarily used for farming, with crops such as corn and soybeans being grown in the fertile soil. The river also offers recreational activities such as fishing, tubing, and kayaking.
