Arizona: Contributing to the stability of the Colorado River System

Lake Mead

Over the last decade, Arizona has conserved more than 3.7 million acre-feet of Colorado Rive water, held back in Lake Mead.

In 2023 alone, we’ve conserved nearly 950,000 acre-feet, including our mandatory 592,000 Tier 2a reduction, plus an additional voluntary contribution of 355,000 acre-feet by our Arizona partners to support stabilizing the Colorado River system.
