Together, these agencies work to strengthen the reliability and resilience of the San Joaquin River and its tributaries.

The San Joaquin Tributaries Authority (SJTA) is a coalition of water agencies who provide a regional approach to protecting California’s water future through collaboration, strategic planning, and environmental stewardship. The San Joaquin Tributaries Authority (SJTA) is a partnership of four public water and energy providers: Modesto Irrigation District, San Francisco Public Utilities Commission, South San Joaquin Irrigation District, and Turlock Irrigation District. SJTA was formed to help protect California’s water future through collaboration, long-term planning, and environmental stewardship.

Water is woven into nearly every part of daily life. It supports our homes, strengthens local economies and helps California farms grow the food families depend on. It also sustains the rivers and habitats that make our region unique.

SJTA member agencies work every day to responsibly manage this essential resource and strengthen water reliability for communities throughout the Bay Area and Central Valley.

Imagine your day without water and take a moment to appreciate the people, infrastructure and partnerships that keep it flowing.

Partnership in action along the Tuolumne River. 💧

On September 19th, SJTA member agencies and community members joined Operation 9-2-99 for a National Cleanup Day event along the north bank of the Tuolumne River in Modesto.

Together, volunteers removed 2 tons of garbage and improved 27 acres of river corridor. These efforts help support river health, enhance recreational spaces, and care for a resource that serves communities, agriculture, wildlife and recreation throughout the region.

Thank you to everyone who contributed their time and energy. This event demonstrates what we can accomplish when agencies, organizations and community members work toward a common goal.
