Arizona’s water authorities are close to entering into a new pact with officials from Nevada and California they hope will restore water levels at Lake Mead and stave off future rationing requirements.

A Tier 1 Colorado River water shortage begins in 2022, triggering a mandatory 512,000 acre-foot reduction to Arizona. The emergency stems from the Lake Mead reservoir reaching water levels not seen since its construction. The designation doesn’t affect Arizona residents, rather the state’s agriculture industry that represents the majority of water usage.
