Decline in the Coachella Valley’s groundwater table was first noted in the 1910s. Concerned that their artesian wells were drying, local residents and farmers formed the Coachella Valley Water District (CVWD) in 1918. CVWD took steps to secure water supplies from the Colorado River that led to the completion of the Coachella Branch of the All-American Canal in 1949. CVWD and Desert Water Agency (DWA) contracted with the State of California for water from the State Water Project (SWP) in the early 1960s with the first deliveries in 1973. At that time, CVWD and DWA implemented groundwater replenishment programs and collected replenishment assessment from groundwater producers. However, continued growth in the Valley resulted in groundwater level declines and overdraft. Twenty years before the adoption of SGMA, CVWD began development of the initial Water Management Plan in 1994 after recognizing the need to sustainably manage the Coachella Valley Groundwater Basin. CVWD adopted the Coachella Valley Water Management Plan in 2002 (2002 WMP) to eliminate groundwater overdraft in the Basin. The 2002 WMP was updated in 2010 (2010 WMP Update) and adopted in 2012. This plan covers the Indio Subbasin of the Coachella Valley Groundwater Basin. CVWD, along with DWA and Mission Springs Water District also prepared the Mission Creek-Garnet Hill Water Management Plan (MCGH WMP) that covers the Mission Creek Subbasin and the Garnet Hill Subarea of the Indio Subbasin. As of 2016, plan implementation is showing positive results with stabilizing water levels throughout much of the Valley. Continued implementation is expected to eliminate water level declines by about 2025.

SGMA and Underrepresented Farmers

Groundwater resources play a vital role in maintaining environmental sustainability in California. During a typical year, approximately 40 percent of the state’s total water supply comes from groundwater. During dry years, groundwater contributes 60 percent (or more) of the state’s total supply, and serves as a critical buffer against the impacts of drought and climate change. This paper responds to concerns expressed by groundwater sustainability advocates that underrepresented farmers have not been included in the development and implementation of Groundwater SustainabilityPlans (GSPs) under the Sustainable Groundwater Management Act (SGMA) of 2014. It contains results from the evaluation of 14 Groundwater Sustainability Plans (12 from the San Joaquin Valley and 2 from the Central Coast) with a focus on stakeholder engagement and projected impacts of groundwater decline on underrepresented farmers.

SGMA was established to provide local and regional agencies the authority to sustainably manage groundwater resources through the development and implementation of GSPs for high and medium priority subbasins (e.g., Shasta Valley). In accordance with SGMA, this GSP was developed and will be implemented by the GSA representing the Basin: the Siskiyou County Flood Control and Water Conservation District. To deal with file size, the Shasta Valley GSP has been divided into three files: Part 1, Part 2,  Part 3 Plan approved by DWR
