Lake Powell Drops to Record Low, Threatening Hydropower

The fall brings Glen Canyon Dam closer to losing its turbines' power and has pushed federal managers to prepare mandatory cuts for the seven Colorado River states.

Overview

  • Lake Powell fell to a record 3,519.91 feet on Saturday, a new low confirmed by the U.S. Bureau of Reclamation that breaks the previous mark from April 2023.
  • The reservoir is now within roughly 30 feet of the minimum power pool at about 3,490 feet, a level below which the dam may not be able to generate electricity for nearly 500,000 homes.
  • Federal officials who already used emergency transfers and paid conservation are preparing to publish specific multi‑year water reductions through 2028 for the seven basin states.
  • Experts say cities have short‑term backups but tribes, small towns and many farms face greater risk because of older water rights and limited money to buy alternatives.
  • Lake Powell and Lake Mead together hold far less water than in past decades after roughly a 20% drop in river flows since 2000 from warming, low snowpack and long‑term use, and experts say only several wet years would reverse the decline.
