Project Goal:

Retrofit flood infrastructure in the Tisdale and Sutter bypasses to enhance fish passage; improve water use efficiency; create floodplain rearing habitat for endangered salmonids; and increase floodplain fish food production benefiting endangered fish populations.


22,000 acres in the Sutter Bypass and 3,200 acres in the Tisdale Bypass.

Project Description

By integrating a 21st-century scientific understanding of how river systems function into the management and operation of California’s outdated water infrastructure, we can create a system where both human systems and the ecosystems on which they depend become more resilient to a changing climate. This project seeks to update flood and water infrastructure and operational practices on the Sutter and Yolo bypasses to add fish benefits (enhance adult fish passage; facilitate long-duration floodplain inundation to create rearing habitat for endangered salmonids; increase floodplain fish food production) to the flood protection, agricultural and waterbird habitat benefits already provided by these managed floodways.
