Won’t Lake Powell fill again?
If average flows return to the Colorado River Basin, water levels at Lake Powell will begin rising again. However, within the coming decade, basin-wide water demand will exceed the amount of water delivered by the Colorado River and Lake Powell will decline again. Water managers are already taking steps to store water in underground aquifers and off-stream storage facilities closer to users. While it is likely that a spike in the hydrograph will raise reservoir levels sometime in the next decade, the institute is advocating for all excess runoff water to be stored in other storage facilities to ensure the continued restoration of Glen Canyon.
