Mark Twain Lake was created by the Cannon Dam impounding the Salt River.
Clarence Cannon Dam is a 138 feet high and 1,940 feet long combination concrete gravity embankment dam. The dam contains 450,000 cubic yards of concrete and 3,000,000 cubic yards of earth-fill.
The dam contains a hydroelectric power plant, with two generators, capable of producing up to 58 megawatts (78,000 hp) of power, or enough to supply a town of 20,000 people. When both units are operating at capacity, as much as 5,400,000 US gallons of water pass through the turbines each minute. 
After several years of camping at Ray Behrens Campground, we decided to sell the camper trailer and purchase a condominium. We wanted to spend more time enjoying the lake and surrounding area and less time setting up and tearing down the camp site.
