Chino Basin Municipal Water District v. City of Chino et al

From “An Evaluation of California’s Adjudicated Groundwater Basins” by Langridge et al: “Chino Basin is one of the largest groundwater basins in Southern California. It abuts Los Angeles County, Orange County, and Riverside County. Over the past few decades, the basin has experienced rapid growth. The southern area was once notable for containing the heaviest concentration of dairy farms in the United States. There is significant subsidence in areas of the basin due to overpumping. While it is often described as a basin with ongoing conflict, there were also significant collaborative efforts to address basin problems during and after the adjudication process. Three different stakeholder groups—overlying agricultural, overlying non-agricultural, and appropriators—negotiated a management plan prior to adjudication, and it was adopted in a 1978 stipulated judgment. Stakeholders agreed on water rights for each group of users. There were multiple additional amendments over the last twenty years adopted in a 2012 restated judgment.”
