With a shared riverscape vision, the region is working to activate this rich land-connecting rivers and creeks to landscapes and communities to ensure they function at their full potential for people, wildlife, agriculture, and recreation. This vision drives efforts to enhance multi-benefit water management, fostering resilience for California's future.
This riverscape is both shaped and defined by the surface water in the region, which is a blessing as the essential ingredient that brings the region to life, while also haunting it with periodic floods and droughts. Surface water gives life to this region through its mosaic of rivers, creeks, and sloughs that support hydropower, recreation, farms, ranches, wildlife habitats, and private wetlands, making the Sacramento River Basin a vital and productive landscape.
