Built to provide hydroelectric power and flow regulation, the Glen Canyon Dam is located on the Colorado River. It's reservoir, Lake Powell, is the second largest man made lake in the country and causes massive amounts of evaporation and seepage loss. In addition, like most other dams, Glen Canyon causes large amounts of silt to build up and has a tremendous ecological effect.
