Following is a list of dams and reservoirs in Indiana. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).
