Fish screens were identified in the Walla Walla Subbasin Plan as  critical limiting factors that must be addressed to achieve recovery of ESA-listed Mid-Columbia steelhead and bull trout and ensure the success of reintroduced spring Chinook salmon in the Walla Walla Basin.  Consistent with the Subbasin Plan the WWCCD has installed 400+ NMFS / WDFW compliant fish screens ranging in size from the very large screens at Hofer dam to the smallest screens available.  This project will provide funding for the  WWCCD to complete installation of a screen on Garrison Creek which is a distributary from Mill Creek. The Garrison Creek screen installation project is nearly complete, however, WWCCD has experienced a cost overrun and lacks the funds to pay for the final phase of work.  WWCCD will expend approximately $167,000 in SRFB funding which will be combined with $12,000 BPA funds to finish construction of this important project.  The Garrison Creek screen will be operated and maintained by the Corps of Engineers.  In the 8 years we have been installing fish screens in the Walla Walla Basin one of the important lessons we have learned is that if fish screens are too difficult to install the irrigators will not use them.  This project will provide funding for addressing issues that jeopardize two irrigators' ability to utilize compliant fish screens that were installed by the WWCCD in 2005 using SRFB funds.
