Mono Lake's Slow Comeback: Decades of Struggle
10 Oct
Summary
- Mono Lake dropped 45 feet due to Los Angeles water diversions.
- New rules in 1994 aim for a lake level of 6,392 feet.
- Drought and climate change hinder the lake's long-awaited recovery.
Mono Lake in eastern California, a crucial habitat for millions of waterbirds, has experienced a slow recovery since 1994. Decades of water diversions by Los Angeles caused its level to drop 45 feet between 1941 and 1982. In response, the state adopted Decision 1631 in 1994, establishing streamflow requirements and export limits to protect the lake's public trust resources.
The 1994 decision set a long-term goal of 6,392 feet above sea level, with predicted attainment by 2014. However, drought, climate change, and ongoing diversions have prevented the lake from reaching this target. A 2025 review highlighted that Mono Lake has never met its management goal, remaining well below the target level.
Recent efforts include restoring 20 miles of creek habitat, with public workshops held in June 2026 to discuss management options. A water budget model is also being developed to assess climate change and diversion impacts. The lake's slow recovery underscores a long history of policy choices that have impacted Great Basin terminal lakes.
