Dams

Water is Power: The thunder and roar that amazed the Lewis and Clark Expedition in 1805 upon discovering the original five great falls of the Missouri can still be experienced throughout the state. While magnificent structures have been built to harness energy and reserve water, many falls still rush freely.

All dams listed are gravity type unless otherwise noted.
