Southern California water supply

Southern California’s water supply primarily relies on imported water from distant sources like the Colorado River and Northern California’s reservoirs, as well as local groundwater and rainfall. The region faces challenges due to droughts, overuse, and climate change, affecting water availability and quality. To manage this, agencies invest in conservation, water recycling, and infrastructure improvements. The goal is to balance the region's high demand with sustainable sources, ensuring reliable water for homes, agriculture, and industry while reducing environmental impacts.
