US Colorado River plan insufficient

Archived — this story has rotated out of today’s deck. It is kept here in full.

The gist

Federal plan cuts Colorado River water up to 40% for California, Arizona, Nevada. Experts say cuts are a stopgap, not enough to avert crisis.

Background

The Colorado River supplies water to 40 million people across seven US states, but has been overdrawn for over a century, worsened by climate change. After years of failed negotiations, the federal government released a 10-year plan on July 31, 2026, with mandatory two-year cuts starting in 2027 for the lower-basin states. Experts warn the cuts are insufficient to prevent reservoirs from reaching critically low levels.
