Fact Sheet: LA County Groundwater Management
Groundwater use in California has historically been unregulated. Los Angeles County is one exception, with seven adjudicated groundwater basins where pumping rights are established and overseen by court-appointed groundwater masters. Groundwater rights were collectively allocated to those who could show a record of pumping through the legally negotiated adjudications. Rights are codified and can be leased or transferred. This has resulted in a system with over 300 rights holders throughout L.A. County today, overseen by groundwater masters who manage pumping levels to ensure safe yield.
