California's Sustainable Groundwater Management Act and the Half-Exemption of Owens Valley Groundwater Basin.

This Comment tells the story of how California's 2014 Sustainable Groundwater Management Act (SGMA) has been applied in Owens Valley. Owens Valley, called Payahuunadü by the Native Paiute and Shoshone people, is the source of the Los Angeles Aqueduct system that exports both surface water and groundwater to Los Angeles. Los Angeles's involvement in the region led to SGMA's half-exemption of Owens Valley Groundwater Basin where all portions of the groundwater basin underlying Los Angeles-owned land is exempt from the Act. This Comment explores how this half-exemption was included in SGMA, describes what it means for local groundwater governance, and details California's Department of Water Resources' shifting approach to Owens Valley that most recently weakened SGMA's protections for the region. This Comment makes direct recommendations to state and local agencies with the goal of better leveraging SGMA to protect Owens Valley Groundwater Basin. SGMA's explicit protections for the "entire basin" mandate a comprehensive approach to protecting not just Owens Valley, but also the other half-exempt California groundwater basins. This Comment specifically points to how state and local agencies can use SGMA to save the irreplaceable high desert wetlands at Fish Slough in Owens Valley from urgent ecological crisis. The Comment ends by advocating for a changed application of SGMA in Owens Valley to better uplift the Owens Valley Paiute and Shoshone Tribes' participation in the Act's implementation.
