City leaders in Los Angeles have announced a major shift in their water management strategy by limiting water diversions from creeks feeding Mono Lake.

This decision aims to preserve the recent rise in the lake’s level and help build a sustainable future for this vital ecosystem.

Export Plans for 2024

The Los Angeles Department of Water and Power (DWP) plans to export 4,500 acre-feet of water from the Mono Basin this year.

This amount is the same as the previous year, enough to supply about 18,000 households annually, despite the city being allowed to take up to 16,000 acre-feet.

Environmental Impact and Historical Context

Decades of water withdrawals from Mono Lake’s creeks have led to significant ecological damage. The lake’s level dropped, exposing unique rock formations called tufa.

A 1994 ruling by the State Water Resources Control Board aimed to restore the lake to a healthier level, highlighting the importance of sustainable water management.

Recent Gains in Lake Levels

Thanks to the historic snowpack in the Sierra Nevada and subsequent runoff, Mono Lake’s level has risen about 5 feet since the start of 2023.

Future Water Management Plans

DWP officials will review water conditions in November and could decide to export additional water if necessary, up to the limit of 16,000 acre-feet.
