The record-low water levels in Lake Powell pose significant risks to water supply and energy generation for millions of people across the Southwest, including states like Arizona, California, and Nevada. The Glen Canyon Dam, which relies on the reservoir to power turbines that supply electricity to nearly 500,000 households, is at risk of losing its ability to generate hydropower. Additionally, the crisis threatens water availability for cities, farms, and smaller communities, particularly those with fewer resources to adapt. Experts warn that without extraordinary measures, the reservoir could reach 'deadpool' levels, where water can no longer flow downstream.
