… The physical infrastructure that enables Colorado River water management is on the verge of its own real and potentially catastrophic crisis — and yet Reclamation has barely acknowledged this, with the exception of an oblique reference in an unposted technical memorandum from 2024. The falling reservoir levels reveal another, deeper set of problems inside Glen Canyon Dam, which holds back the Colorado and Lake Powell. The 710-foot-tall dam was designed for a Goldilocks world in which water levels would never be too high or too low, despite the well-known fact that the Colorado is by far the most variable river in North America. … Insufficient or no flows through Glen Canyon Dam would be a disaster of unprecedented magnitude, affecting vast population centers and some of the biggest economies in the world, not to mention ecosystems that depend on the river all the way to the Gulf of California in Mexico.
