RESCAT-2008-112-00Proposal Version 1Existing ProjectPending BPA Response2008-112-00Resident Fish Loss AssessmentThis 3-year loss assessment project supports the evaluation of the ecosystem conditions and function affected by the construction and operation of Chief Joseph Dam and Grand Coulee Dam. The project will cooperatively develop biological and environmental objectives that will relate the performance outcomes for resident fish as mitigation for impacts from Chief Joseph Dam and Grand Coulee Dam. The study area includes Lake Rufus Woods, Lake Roosevelt and tributaries upstream and downstream of Chief Joseph Dam and Grand Coulee Dam that are affected by dam operations. The overall goal of this project is to quantify hydrosystem impacts to resident fish so that solutions can be identified for remedying the factors limiting resident fish production. This project will quantify both construction and operation losses, and will be based on the application of various methods ranging widely in complexity and data needs. Because there are no established methods for resident fish loss assessments, and because of the need for consistency throughout the Columbia River Basin, this project will begin by forming an advisory team comprised of regional fish managers as a means of collaboratively advising on the direction that the loss assessment should take. The first objective is to evaluate the reference condition and contemporary biotic and abiotic factors controlling the resident fish community composition and abundance. The second objective is to quantify the effects of dam construction and operation on the biotic and abiotic factors controlling the resident fish community composition and abundance.Sheryl Sears (Inactive)09/15/201112/11/2020Sheryl Sears (Inactive)Colville Confederated Tribes, Pacific Northwest National LaboratoryHydrosystemNoneResident Fish, Regional Coordination, and Data Management Category ReviewResident Fish, Regional Coordination, and Data Management Categorical ReviewFish Accord
