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.

Reliable water touches every home, every community and every meal. 💧🌾

A survey of 1,500 Bay Area and Central Valley voters found that two in three are very or extremely concerned about having enough water for their homes and during extended droughts. Nearly as many in both areas are concerned about having the water needed to grow California crops and help keep food affordable.

Although these communities are separated by geography, their priorities are closely connected. Regional collaboration advances practical solutions that strengthen water reliability throughout California.
