West Point Lake is a man-made reservoir impounded by the West Point Dam, a dam built by the U.S. Army Corps of Engineers on the Chattahoochee River that provides flood control and hydroelectric power. It also provides a reservoir for water to aid the navigation of the lower Chattahoochee. The reservoir extends for about 35 mi (56 km) along the Chattahoochee River near the Alabama-Georgia state boundary.
