Figure 2. Willamette basin showing multipurpose dams and fish hatchery facilities 1.6) Type of program Isolated harvest program 1.7) Purpose (goal) of program The goal of this program is to provide fish for sport fisheries and to replace lost fisheries caused by habitat and passage loss/degradation in the Willamette basin while minimizing negative effects on ESA-listed fish. 1.8) Justification for the program The hatchery program was initially started in the UWR in the late 1960s as mitigation for lost winter steelhead production caused by the construction of the Foster and Green Peters dams. Native winter steelhead had not been providing the angling opportunity desired by sportsmen and fisheries managers, because they spawned and were essentially gone from the system by late May. High water through the late winter and spring often impacted, and sometimes substantially reduced, sport angling efforts for winter fish. By the time dependable weather rolled around, the winter fish were gone. The creation of a healthy summer run was intended to expand the duration of the steelhead angling season through the summer and fall. 1.9) List of program “Performance Standards” Peven and Keefe (2010) developed performance standards and indicators for the WHMP summer steelhead program. Table 4 provides the performance indicators and standards that were primarily identified within Peven and Keefe (2010). It is important to note that many of these performance standards need vetting through the WHMT. Table 4.
