RESCAT-1990-018-00Proposal Version 1Existing ProjectPending BPA Response1990-018-00Lake Roosevelt Rainbow Trout Habitat and Passage ImprovementOur goal is to restore healthy and harvestable salmonid populations through rehabilitation of stream habitat and restoration of ecological function in the riparian corridors of streams upstream of Grand Coulee Dam within the boundaries of the Colville Confederated Tribes reservation. Land use practices including residential and agricultural development, road building and logging have degraded habitat conditions and blocked upstream passage throughout many of the watersheds where historic tribal fishing once occurred. In order to identify and prioritize the appropriate fixes, we first need to inventory and understand the magnitude of the causes of that degradation. With that assessment in hand, we can form a plan to treat the root cause of the habitat degradation, rather than reacting to the symptoms which are observed at any one site. It is our intention to implement a restoration strategy that will restore and be consistent with the ecological processes described in the Upper Columbia Recovery Technical Team (UCRTT) Biological Strategy and the process-based principles outlined in Beechie et al. (2010). To accomplish this, our implementation strategy will follow the basic hierarchical strategy outlined in Roni et al. (2002). This approach begins with an assessment and inventory of the habitat conditions and degradations. Where habitat is degraded, we will seek first to reconnect isolated habitats then restore processes such as riparian condition and floodplain function before implementing actions that build temporary habitat. Based on the work of previous projects we know that there are a considerable number of culvert barriers and an extensive history of grazing in the riparian zone. Therefore our project will begin implementation of actions under an opportunistic paradigm while the assessment is occurring. With the assessment in hand (year 3) we will re-focus to a more strategic approach, working down through the hierarchy of sequenced actions. Obviously, if there are apparent lethal flow or water quality problems those areas will be screened out of the list of potential projects for early implementation. Eventually, in unconfined areas where the channel migration zone is unimpeded and the stream has access to its floodplain but riparian vegetation is still recovering we may consider restoring instream habitat for short-term benefits through the addition of large woody debris (LWD). Additionally, in areas that have been heavily impacted by grazing or if rip rap is being removed, some LWD additions may be necessary as part of a treatment that accelerates the recovery of the damaged riparian vegetation and streambank.Jason McLellan09/15/201102/26/2014Jason McLellanColville Confederated TribesHabitatNoneResident Fish, Regional Coordination, and Data Management Category ReviewResident Fish, Regional Coordination, and Data Management Categorical ReviewFish Accord
