Central Valley Region


Central Valley

The Central California region is managed from our office on the Russian River in Windsor just 10 minutes north of Santa Rosa. Central Valley projects are focused on restoration and management of floodplain habitats. The Nigiri Project on Knaggs Ranch in Yolo Bypass (Between Woodland and Sacramento) is our flag ship project for the Central Valley.

Regional Goal

Leverage floodplain science and messaging to influence policy that expedites on-the-ground infrastructure improvements to promote robust fisheries and self-sustaining populations of wild salmonids in the Central Valley by allowing fish to access and benefit from functioning floodplains.

Region Director: Jacob Katz, Ph.D.

Jacob was born with gills. Fascinated with what happened below the water line he grew up chasing fish in every creek, puddle, river and pond he could find. Eventually, Jacob was hooked by school taking a Ph.D. in ecology at the UCD Center for Watershed Sciences under Dr. Peter Moyle. As Central California Director, he focuses on integrating biologic science and natural history into the management and operation of California’s water infrastructure and developing ways to get greater fish and wildlife benefit out of working agricultural landscapes while ensuring that California is always home to self-sustaining runs of wild salmon.
