Averaging a major dam every 72 miles (116 km), the rivers in the Columbia watershed combine to generate over 36,000 megawatts of power, with the majority coming on the main stem. Grand Coulee Dam is the largest producer of hydroelectric power in the United States, [ 1 ] generating 6,809 megawatts, over one-sixth of all power in the basin.
