About Us


Hello​

​

Everyday, we have you in mind as we take care and manage the underground water supply all of us in the San Gabriel Valley rely on. About 80% of the water you depend on comes from this one amazing water supply source, deep down underground — the Main San Gabriel Groundwater Basin. In 1973, our organization, the Watermaster, was created by the Los Angeles County Superior Court to manage the Main San Gabriel Basin.

​

We are sharing the story of our underground water because all of us in the San Gabriel Valley have a role in its care, including you, your family and friends. Please help us share this story, the story of the waters that connect us.
