Gavins Point Dam/ Lewis & Clark Lake
Dam and Powerplant
Point Dam, part of the 1944 Pick-Sloan Plan, plays an important
role in the successful operation of the six main stem dams
and reservoirs on the Upper Missouri River basin. The dam
was completed in 1957 at a cost of $51 million.
released from the five upstream dams is used at Gavins Point
Dam for production of hydroelectric power. The Gavins Point
Dam generators provide enough electricity to meet the annual
needs of 65,000 people. Controlled releases from the dam enhance
navigation and minimize erosion on the Missouri River to St.
Louis, Missouri. Gavins Point Dam, along with Lewis and Clark
lake provide $35 million in benefits to the public annually.
These benefits include power generation, flood damage
navigation support, and fish and wildlife enhancement.
