Overview
Mark Twain Lake is an approximately 18,600-acre reservoir on the Salt River in Monroe and Ralls counties in northeastern Missouri, southwest of Hannibal. It was created when the U.S. Army Corps of Engineers completed Clarence Cannon Dam in 1984. The multipurpose project provides flood risk management, hydroelectric power, water supply, fish and wildlife habitat, and recreation, with incidental benefits to Mississippi River navigation.
