. 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. Negit Island, a breeding site for birds, developed a land bridge and became susceptible to land-based predators such as coyotes.

Formation of the Mono Lake Committee

In 1975, David Winkler, Jefferson Burch, and Christine Weigen obtained a grant from the

, 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 soon became the committee's first director; he joined Gaines and others in lobbying California politicians Mono Lake is an important habitat for migratory birds (including the

). The lowering of the water level endangered the bird nesting grounds on Negit Island in the middle of the lake: a land bridge had formed, which allowed predators to attack the bird nests.

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.
