Lake Powell Is Disappearing — And It's Taking Hoover Dam's Power With It
America's second-largest reservoir has fallen to historic lows, threatening power for millions across the Southwest.
3,525 ft
Lake Powell Water Level in 2022
Its lowest since the reservoir first filled in the 1960s — just 25 ft above "dead pool," where water can no longer flow through Glen Canyon Dam
Power at Risk
Glen Canyon Dam: 5 States, Millions of Homes
The dam generates up to 1,320 megawatts of electricity for Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming — but plummeting water levels have slashed output by over 50%.
Agriculture Under Threat
Farmers in the Southwest Are Running Out of Water
The Colorado River supplies irrigation to 5.5 million acres of farmland. As Lake Powell and Lake Mead drain, mandatory water cutbacks are forcing farmers to fallow fields and abandon crops.
Federal Response
The Bureau of Reclamation has declared unprecedented water shortages on the Colorado River in consecutive years. In 2026, Tier 3 water cuts reduced Arizona's allocation by 720,000 acre-feet — the largest mandatory cutback in the river's history.
23 Years
of Ongoing Megadrought
Scientists call the current drought in the American West the worst in 1,200 years — driven by climate change, rising temperatures, and reduced snowpack
What Can Americans Do?
Fix leaks, reduce lawn watering, choose drought-tolerant plants, and support climate-smart water policy. Every gallon counts when reservoirs are at historic lows.
