Water diversions to Los Angeles dried the lake in the early 20th century.<\/p>\n<p>Carlos Avila Gonzalez\/S.F. Chronicle<\/p>\n<p>Mono Lake stands out in the high desert of eastern California, a disc of blue amid a landscape of sagebrush and sandy soil. In 1872, Mark Twain called it \u201cthis lonely tenant of the loneliest spot on earth.\u201d<\/p>\n<p>Lonely as it may be, legal cases involving Mono have revolutionized environmental law in California, the American West and the U.S., bringing about important changes to water use and air quality regulations in recent decades and showing the way ahead for tribal resource rights today.<\/p>\n<p>In the early 20th century, the Los Angeles Department of Water and Power built the Los Angeles Aqueduct to capture snowmelt from the eastern face of the Sierra Nevada and channel water to the city. Within a decade, California\u2019s Owens Lake, where the water had naturally flowed and collected for thousands of years, dried up. In 1941, the Los Angeles utility added an extension that allowed it to drain water from the nearby Mono Basin, tapping rivers and streams that had long fed Mono Lake.<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>Mono was known for its abundant bird life, harboring up to 1 million birds of 300 different species. But by the 1970s, the lake\u2019s plants were dying and dust storms clouded its shoreline. People who loved the lake were worried\u00a0\u2014 including student researchers, who published \u201c<a href=\"https:\/\/www.monobasinresearch.org\/onlinereports\/1976study\/ecologicalstudyofmonolake.pdf\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">An Ecological Study of Mono Lake, California<\/a>,\u201d\u00a0a 200-page report distributed by UC Davis\u2019s Institute of Ecology.<\/p>\n<p>Mono is a \u201c<a href=\"https:\/\/www.monolake.org\/learn\/aboutmonolake\/naturalhistory\/chemistry\/\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">triple water<\/a>\u201d lake, with three types of minerals (chlorides, carbonates, and sulfates) dissolved in it, making it two to three times saltier than the ocean. The students\u2019 Mono Lake study, published in 1977, showed that as the lake\u2019s water level dropped and its salts became more concentrated, its brine shrimp and alkali flies\u00a0\u2014 tiny invertebrates that fed the lake\u2019s birds by the millions\u00a0\u2014 struggled to reproduce.<\/p>\n<p>San Francisco Chronicle Logo<\/p>\n<p>Make us a Preferred Source to get more of our news when you search.<\/p>\n<p><a href=\"https:\/\/www.google.com\/preferences\/source?q=sfchronicle.com\" data-link=\"native\" role=\"button\" aria-label=\"Add Preferred Source\" class=\"td300 cp f aic jcc disabled:cd wsn px24 y40px px16 py8 buttonSm fs13 xs:fs16 xs:buttonLg bg-primaryAccessible hover:o80 c-white disabled:bg-gray300 disabled:c-gray600 border bn tac br2\"><\/p>\n<p>Add Preferred Source<\/p>\n<p><\/a><\/p>\n<p>\u201cThe present populations of these animals will not be able to withstand the increasing salinity predicted for Mono Lake,\u201d the students wrote. That spelled doom for the lake\u2019s abundant gulls, grebes and phalaropes.<\/p>\n<p>Armed with these findings, in 1979, a group of environmental organizations <a href=\"https:\/\/scocal.stanford.edu\/opinion\/national-audubon-society-v-superior-court-30644\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">sued the Los Angeles Department of Water and Power<\/a> over the aqueduct\u2019s effects on Mono, seeking to stop the utility from diverting so much water. They based their argument on the public trust doctrine, a legal principle that holds that certain natural resources are held in trust by the state for the benefit of the public. In 1983, the California Supreme Court ruled that protecting Mono Lake\u2019s ecosystem fell under this doctrine. The court left the details to the state <a href=\"https:\/\/www.waterboards.ca.gov\/\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">Water Resources Control Board<\/a>, which implemented cutbacks to Los Angeles\u2019 water diversions so that more water would reach Mono and the lake could eventually return to a healthy level.<\/p>\n<p class=\"uiTextSmall f aic jcc\">Article continues below this ad<\/p>\n<p>A decade later, Mono was the subject of more legal innovation\u00a0\u2014 this time, a new application of the <a href=\"https:\/\/www.epa.gov\/laws-regulations\/summary-clean-air-act\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">Clean Air Act<\/a>, the federal law that regulates air emissions. The Great Basin Unified Air Quality Control District, responsible for regulating air pollution in Eastern California, sought to curb dust storms that billowed off the shorelines of Mono and Owens lakes\u00a0\u2014 and to hold Los Angeles accountable for them. Caused by falling water levels from years of aqueduct siphoning, the storms were causing respiratory issues for local residents.<\/p>\n<p>Yet this required the agency to convince the courts that the Clean Air Act could regulate not just refinery or factory smokestack emissions, but also those from natural sites altered by human impact. After a David-and-Goliath fight, the 9th U.S. Circuit Court of Appeals in San Francisco decided that Los Angeles had to bring the Mono and Owens lake beds into compliance with dust standards. Not only could they not divert as much water, but they had to clean up the damage that had already been done.<\/p>\n<p>Now the Mono Basin could be part of making water history again. In 2017, California began using <a href=\"https:\/\/www.waterboards.ca.gov\/tribal_affairs\/beneficial_uses.html\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">Tribal Beneficial Uses<\/a>\u00a0\u2014 water quality standards keyed to protecting traditional tribal fisheries and cultural practices\u00a0\u2014 to incorporate long-ignored tribal needs into state environmental management. The first regional board to incorporate Tribal Beneficial Uses into a watershed management plan was the <a href=\"https:\/\/www.waterboards.ca.gov\/lahontan\/water_issues\/programs\/basin_plan\/docs\/2024\/r6tbureport.pdf\" data-link=\"native\" class=\"\" rel=\"nofollow noopener\" target=\"_blank\">Mono Basin<\/a>\u00a0in 2020. The following year, the local Mono Lake Kootzaduka\u2019a tribe requested Tribal Beneficial Uses for cultural practices and tribal subsistence fisheries, initiating a multi-year process of research and consultation.<\/p>\n<p>\u201cWe\u2019ve never been at the table to have conversations regarding Mono Lake or any of our traditional lands. This is \u2026 a long time coming,\u201d said tribal chairperson Charlotte Lange at an April 2024 Lahontan Regional Water Quality Control Board hearing. The planned November 2024 adoption of the Mono Basin Tribal Beneficial Uses was delayed but remains on the near horizon, Daniel Sussman, a scientist for the California\u00a0 Water Resources Control Board, told me.<\/p>\n<p>Guest opinions in Open Forum and Insight are produced by writers with expertise, personal experience or original insights on a subject of interest to our readers.
