where does southern california get most of its water?
the colorado river
the inland feeder is a high capacity water conveyance system that connects the california state water project to the colorado river aqueduct and diamond valley lake. the metropolitan water district of southern california designed the system to increase southern california's water supply reliability in the face of future weather pattern uncertainties, while minimizing the impact on the san francisco bay/sacramento–san joaquin river delta environment in northern california. the feeder takes advantage of large volumes of water when available from northern california, depositing it in surface storage reservoirs, such as diamond valley lake, and local groundwater basins for use during dry periods and emergencies. this improves the quality of southern california drinking water by allowing more uniform blending of better quality water from the state project with colorado river supplies, which has a higher mineral content.
