Lake Powell, a vital reservoir, plunges toward unprecidented low levels as water crisis deepens in US west

Experts say the critical reservoir system is careening toward a breaking point as the US west’s climate warms and dries Lake Powell, US’s second-largest reservoir, threatens to plunge to unprecedentedly low levels this year after a historically bleak snowpack failed to raise its water level, scientists and water experts have said, adding renewed urgency to stalled talks over how to conserve a water source depended on by tens of millions of people in the US south-west. The 185-mile Colorado River reservoir currently stands at about 23% of its capacity, or roughly 5.6m acre-feet. Lake Powell fell below that level for a few months three years ago. But those 2023 levels were recorded in the winter, when the reservoir straddling the Utah-Arizona border hits its lowest ebb. Spring runoff carried the level back up to 9.6m acre-feet by June, according to data from the US Bureau of Reclamation. Continue reading...
