Lake Mead’s “bathtub ring” is set to become even more pronounced this year.

The lingering drought is the overriding reason that the lake’s water level will fall again in 2022, but it’s also because less water will be released upstream on the Colorado River from Lake Powell.

This month, the seven Colorado River Basin States — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — agreed with federal officials’ recommendations to institute a 480,000 acre-foot reduction from Glen Canyon Dam on Lake Powell to reduce the risk of the lake declining below 3,490 feet.
