SSJID At SSJID - the South San Joaquin Irrigation District.- we provide water for irrigation & drinking and generate clean electric power.

In 1909, the South San Joaquin Irrigation District was established to provide a reliable and economical source of irrigation water for the areas around Escalon, Manteca and Ripon. SSJID's historic water rights allow for several hydroelectric power plants on a series of dams and reservoirs on the Stanislaus River. SSJID and Oakdale Irrigation District completed the original Melones Reservoir in 192

6, and have co-owned the Tri-Dam Project, consisting of Donnells, Beardsley and Tulloch reservoirs and powerhouses since 1957. In 2005, as unprecedented urban growth replaced agricultural land, the District expanded into providing domestic water service to South San Joaquin County cities with its state-of-the-art water treatment plant. In 2009, SSJID completed a 1.4 megawatt solar farm that provides nearly all of the electricity to run its water treatment plant, and the District passes on a 15% savings on power costs to the cities who participate in the treatment plant. For several years, the District has been moving towards providing retail electric service as well, aiming to cut electric bills of those in its service territory by 15% across the board.

SSJID recently welcomed members of the Almond Board Collaboratory for a presentation and discussion about the District's operations and services.

The Collaboratory brings together universities, nonprofit organizations, and food developers working together on projects related to sustainable agriculture, nutrition science, and upcycled food products. During their visit, participants received an overview of SSJID and learned more about the District's role in water management.

Visits like these help strengthen connections between water agencies, researchers, and agricultural leaders working to address challenges and shape the future of farming.

Did you know golden mussels can spread by hitching a ride on boats, trailers, and other water recreation equipment?

Once introduced, these invasive mussels can damage ecosystems, impact water quality, and create costly problems for water infrastructure.

Do your part to help stop the spread by remembering to Clean. Drain. Dry.

🧽 Clean all aquatic plants, animals, and mud from your watercraft, motor, trailer, and equipment.

πŸ’§ Drain all water from motors, live wells, ballast tanks, buckets, and any other areas that hold water before leaving the waterbody.

β˜€οΈ Dry your watercraft and equipment completely between uses, including compartments, anchor lines, and other areas where moisture can remain.

Together, we can help protect California's waterways. To learn more about specific inspection and prevention requirements at your local reservoir, visit https://loom.ly/c5W0HDE.

As part of a statewide agriculture tour, master's-level students from Stephen F. Austin State University visited SSJID's pressurized irrigation project to learn about irrigation operations and water management. The group represented a variety of fields, including Agricultural Engineering, Agricultural Education, Agricultural Communications, and Animal Science.

Their California tour was designed to broaden understanding of agriculture, water resources, and issues affecting producers across the state, including in Stanislaus and San Joaquin counties.

Thank you for visiting SSJID! We appreciated the opportunity to share our operations and discuss the important role water plays in supporting local agriculture.

Flowing from the Sierra Nevada to the heart of the Central Valley, the Stanislaus River supports farms, wildlife habitats, recreation, and the water needs of communities throughout the region.

At SSJID, caring for this waterway is part of our everyday work. Through responsible water management and long-term planning, we help ensure this resource continues to serve the people and industries that rely on it.

National Rivers Month highlights the importance of freshwater ecosystems and the lasting value they provide. We are proud to play a role in preserving the benefits it delivers. πŸ’§
