. As time passed, this both reduced the level of the lake and dried out the lower sections of the source streams. By 1981 the level of the lake had been reduced to 6372' above sea level, with the lake's volume cut in half, and its salinity doubled.

Formation of the Mono Lake Committee

, with help and encouragement from ecologist David Gaines, to study the ecology of Mono Lake. Gaines had found that, starting in 1941, LADWP's diversions of water from Mono Lake's inflow creeks had caused it to lose half its volume and double its salinity. These changes, Gaines reported, reduced the ability of the lake to support its saline ecosystem. During 1976–1977, Gaines witnessed the lake's water level drop even further, and he determined to take action.
The committee was founded in March 1978 by Gaines, David Winkler, Sally Judy and Mark Ross. Gray Brechin Gray A. Brechin (born September 2, 1947) is an American geographer, architectural historian, and author. He is the founder and Project Scholar of The Living New Deal based at the U.C.

As of 2018, the water level in Mono Lake has risen of the required . Los Angeles made up for the lost water through state-funded conservation and recycling projects.
Current Status and Activities
The Mono Lake Committee currently monitors the status of the lake and the compliance of the LADWP with the court decision, supports scientific research in the Mono Lake region, and is actively working on restoring the incoming stream environments. They also provide extensive educational activities to schools and the general public, and maintain an office, information center, and bookstore in Lee Vining, CA that also serves as the Lee Vining Chamber of Commerce.
