DWR's Yolo Bypass Habitat Restoration Program works to:

  1. Identify and implement actions that will address the floodplain habitat enhancement and fish passage improvement requirements of NMFS BO RPA actions I.6.1, I.6.3, I.6.4, and I.7.
  2. Facilitate intra-agency and interagency planning discussions to achieve the above goal.
  3. Facilitate stakeholder and public involvement and engage interested stakeholders in the planning process.
  4. Utilize and incorporate sound science, sustainability and ecological principles, and the best available information to develop floodplain habitat enhancement and fish passage designs.
  5. Implement actions that achieve the biological objectives and are compatible, to the extent practicable, with existing uses and other planning efforts for the Yolo Bypass.

DWR works with the U.S. Bureau of Reclamation, other state and federal agencies, non-government organizations, stakeholders, and the public to plan and implement the projects.
