The Glen Canyon Dam forms Lake Powell and the Hoover Dam forms Lake Mead. Below 3,490 feet of elevation, Lake Powell dips into a zone where the generation of hydropower by water flowing through the Glen Canyon Dam becomes unreliable. Lake Powell is in crisis. 1. The idea that these smaller upstream reservoirs can continue to compensate Powells losses, thats not the case, he said. At that point, Upper Basin states would start delivering water from their other reservoirs to Powell. Lake Powell upstream of Lake Mead on the Colorado River is at its lowest level on record.
