Grand Coulee Dam in Washington State, long one of the nations top tourist attractions, is the largest concrete structure ever built by man. The spray of twelve pipes in the centre of the picture are the outlets for the water pumped from the pool behind the dam into the Grand Coulee above. Here the water is stored for release in irrigating the million acre Columbia Basin Irrigation Project to the South. The dam is 46 stories high, higher than the Washington Monument. It is 12 city blocks long, 500 feet thick at its base. Now colour lighted at night, visitors are transfixed as 120 different colour combinations are played upon the dam during each half hour cycle brushing the massive drape of white water with their tints. The dam backs up the Columbia River 151 miles into Canada, to form Lake Roosevelt, a boaters paradise. The dam wa eight years building (1933 to 1941). The dam is the southern entrance to North Central Washington's Okanogan Highlands area. It is the first and largest of the series of great dams built or being built or planned for Columbia.
