As the Colorado River shrinks, federal officials consider overhauling Glen Canyon Dam

 The desiccation of the Colorado River has left Lake Powell, the country’s second-largest reservoir, at just 23% of capacity, its lowest level since it was filled in the 1960s.

With the reservoir now just 32 feet away from "minimum power pool" — the point at which Glen Canyon Dam would no longer generate power for six states — federal officials are studying the possibility of overhauling the dam so that it can continue to generate electricity and release water at critically low levels.

A preliminary analysis of potential modifications to the dam emerged during a virtual meeting held by the federal Bureau of Reclamation, which is also reviewing options for averting a collapse of the water supply along the river. hese new discussions about retooling the dam reflect growing concerns among federal officials about how climate change is contributing to the Colorado River's reduced flows, and how declining reservoirs could force  major changes in dam management for years to  come...
