American Falls Reservoir is formed by American Falls Dam, which is a major facility on the Mindoka Project. Managed by the Bureau of Reclamation, Snake River Area Office, Bingham County; and the city of American Falls, this 87 square mile (56,000-acre) reservoir offers 100 miles of shoreline. Built primarily as a water storge reservoir for irrigation, it also provides electric power and flood control protection. When completely full, the reservoir is the largest reservoir on the Snake River and in Idaho. Boating, canoeing, fishing, swimming, wildlife viewing, picnicking, jet boats, water skiing, wildlife viewing, and windsurfing are the major recreation activities at American Falls Reservoir, located in Southeastern Idaho. American Fall's fish species include rainbow, brown, and cutthroat trout, crappie, yellow perch, white fish, bullhead and channel catfish. Season open year-round, however the fishery is dependent upon the availability of water to maintain the minimum pool necessary to carry over fish from year to year.
