Supplement Analysis for the Watershed Management Program EIS (DOE/EIS-0265/SA-90) - Naches River Water Treatment Plant Intake Screening Project
- Bonneville Power Administration (BPA), Portland, OR (United States)
BPA is proposing to fund the upgrade of the intake structure for the City of Yakima’s Water Treatment Plant. The existing traveling water screen at the intake does not achieve the current fish screening criteria as defined by Washington State Law and as provided in guidance from the National Marine Fisheries Service. Permanent modifications to the intake system including installation of a fish screen and bypass system are necessary to eliminate mortality and take of ESA listed and non-listed salmonids, as well as resident fish at this location. This project will include: modifications to bypass the existing intake system; the construction of a new intake structure with approved fish screens; installation of a 48-inch diameter pipeline connecting the new intake to the existing intake structure; a reduced intake channel separating PacifiCorp Powerhouse return water/ Naches River water from the irrigation and Wapatox waste ditch return water; modifications to the auxiliary headgates; increased height on the upstream end of the channel wall; and a new outfall structure with plunge pool and upstream migrant barriers.
