Additional Keywords: Phase 1 Review; Phase One Review; TRRP, restoration From the Introduction: "The Trinity River Restoration Program (hereafter the Program) requested that their Science Advisory Board (SAB) evaluate the channel rehabilitation projects built by the Program to mitigate the downstream effects of the Trinity and Lewiston Dams on naturally spawning salmon. Such projects were identified and recommended in the Program’s flow evaluation study (USFWS and HVT 1999) and their efficacy was to be assessed after half of them were built (hereafter referred to as Phase 1). The rehabilitation projects involve mechanical alteration of the channel, riparian planting, wood placement, and gravel augmentation (bar placement and high-flow injection) to restore fish and wildlife habitat in accordance with the Record of Decision (ROD; USDOI 2000). These actions are part of the Program’s management strategy of fostering a dynamic channel and floodplain system with a proper bed substrate and temperature regime for salmonids via managed dam releases, sediment augmentation or retention, and bank rehabilitation (USFWS and HVT 1999). The ultimate goal of these actions is to restore salmonid populations, with a specific focus on in-river production of presmolts from the restoration reach, which extends 64 kilometers along the mainstem river from Lewiston Dam to the confluence of the North Fork Trinity River."
