Lake Powell is part of the great Colorado River Project. A series of dams along the Colorado River that keeps the water at a constant flow, and the areas free of drought and flood. Glen Canyon Dam holds the water back to form Lake Powell. The first of the manmade lakes along the Colorado River. What makes Lake Powell so unique is that the lake encompasses what was once a desert badlands with sandstone arches, buttes and bridges. The lake provides spectacular scenery along the shores from steep red cliffs to striking arches that you can drive a boat through. There is all kinds of water recreation available at Lake Powell.
