The Mono Lake Committee (MLC) is a non-profit environmental organization dedicated to protecting and restoring the Mono Basin ecosystem, focusing on Mono Lake, a unique and ancient saline lake in California. Founded in 1978, the MLC has been instrumental in advocating for the lake's preservation and raising awareness about wise water use[2][6]. **History and Key Achievements:** The MLC's most significant achievement was its successful lawsuit against the Los Angeles Department of Water and Power (LADWP) in 1983. This landmark case, supported by the Audubon Society, established that the public trust doctrine overrides prior water rights, ensuring that Mono Lake's water levels are maintained for environmental protection[6]. The California State Water Resources Control Board later set a target lake level of 6,392 feet above sea level to balance environmental and municipal needs[5]. **Current Status:** Today, the MLC continues to monitor the lake's status, support scientific research, and engage in educational activities. It operates an information center in Lee Vining, offering resources and guided tours[3][6]. The organization has grown to include over 16,000 members, emphasizing community involvement in environmental conservation[3]. **Notable Aspects:** Mono Lake is renowned for its natural beauty, hosting trillions of brine shrimp and millions of birds, and its distinctive tufa towers. The MLC's efforts have ensured the lake's water level rose significantly, though it remains below the target level[2][5]. The organization's work exemplifies a balanced approach to environmental conservation and human needs, making it a model for sustainable practices in the business and technology sectors[4][6]. In summary, the Mono Lake Committee is a pioneering environmental organization that has achieved significant legal and environmental milestones, showcasing the importance of community-driven conservation efforts. Its dedication to preserving Mono Lake serves as an example of how organizations can effectively balance environmental protection with human needs.
