This project represents support functions the BOR provides toward the O&M of the Phase II screens. These activities complement the WDFW O&M activities under project number 1992-009-00. The BOR provides full service O&M for six screens located on the Yakama Nation Reservation.This proposal provides for continuation of funding for the existing comprehensive operation & maintenance program by the USBR of BPA owned Yakima Phase II fish screening and trapping facilities. USBR currently operates and maintains twenty-four sites, with an estimated 3 more sites due to be added by the end of the Phase II construction program in 2004. These facilities are located at irrigation diversions throughout the Yakima River Basin, and were constructed to bring the old screen sites into compliance with current regional fish screen biological protection criteria adopted by the Columbia Basin Fish and Wildlife Authority (CBFWA) in 1995. The target objectives of that program are (1) reduce fish delay to a degree approaching zero; (2) reduce the possibility of injury or mortality to a degree approaching zero; and (3) allow fish to pass with little additional expenditure of energy.
