For decades, the communities in Alameda, Merced, San Francisco, San Joaquin, San Mateo, Santa Clara, Stanislaus, and Tuolumne Counties, which comprise a significant portion of Northern California, have benefitted from the stability, resilience, and quality of the resources managed by SJTA members.
The residential, business and agricultural customers we serve have invested billions of dollars in the efficient, sustainable operations and infrastructure of our systems, including investing in scientific research and adaptive management to effectively protect the ecosystems within the Tuolumne and Stanislaus River watersheds.
