Project Goal:

Scientifically demonstrate that productivity created by shallow inundation of floodplains is foundational to supporting self-sustaining populations of fish and wildlife in the Central Valley.


8,000 acres South and 5,000 acres North of fish-bearing floodplain re-activated for a min. of 4 weeks in nearly all water years.

Project Description

Now in its sixth year, this managed floodplain project continues to expand with Nigiri North in the Yolo Bypass and Nigiri South in the Sutter Bypass. Working in partnership with UC Davis Center for Watershed Sciences, the science-based program has demonstrated that productivity created by shallow inundation of floodplains on dormant rice-fields is foundational to supporting self-sustaining populations of fish, particularly endangered winter-run Chinook salmon, and wildlife in the Central Valley. In this next phase of the project we will leverage the floodplain research success and pilot projects to influence state and federal water policy in order to expedite construction of multi-benefit water infrastructure improvements at the landscape scale.
