The initial proposal for the dam came in 1937 for flood control on the Salt River. Money was appropriated in October 1962 in the Flood Control Act. Actual construction was begun in 1970 and it was completed in 1983. The dam was initially name the Joanna Dam but was renamed for Clarence Cannon, chairman of the House Appropriations Committee and longtime member of the U.S. House of Representatives, who was instrumental in obtaining the funding for the dam.
The dam is located about 63 upstream of the Salt River's confluence with the Mississippi River and impounds the 18,000 acre Mark Twain Lake. The dam is 1940 feet long and 138 feet high. The dam contains 450,000 cu yd (340,000 m3) of concrete and 3,000,000 cu yd (2,300,000 m3) of earth-fill.
The dam has a hydroelectric power plant, with two generators, capable of producing up to 58 MW of power, or enough to supply a town of 20,000 people.
Mark Twain lake is known for its recreational opportunities including boating and fishing. There are several campgrounds located around the large lake.
