DESCRIPTION
This project will modernize Badger Mountain Irrigation District's six traveling fishscreens that protect fish from coming up into our pumps. We currently have 5 active screens with the need for one additional one. The main structure is there and useable, the motorized fishscreens need to be installed.
Badger Mountain Irrigation District (BMID) installed six new, belt-driven fish exclusion screens at BMID’s existing water diversion intake from the Yakima River. The screens replaced five 38-year old screens that are nearing the end of their service life and one screen that was absent. The screens are located on the Yakima River in the proximity of 540 Columbia Park trail, Richland, WA. Species protected by the screens include juvenile steelhead, juvenile summer and fall Chinook, and juvenile Coho.
The new traveling screens were sized to match the old screens and housed in the existing river station. Removal and installation of the screens was done by a boom truck lifting the units vertically up and out of each individual chambered pocket within the existing concrete structure. Upgrading the screens will promote more consist running time and more effective debris clearing of the screens, making for a positive barrier between our intake diversions and the juvenile fish species present at this site in the lower Yakima River.
Note that the actual project cost ($309,452) was 76% more than the proposed cost ($176,310) reported in PRISM. This is because the proposed cost in PRISM reflected only miminal match; it did not reflect actual total project cost. The actual total project cost did not change, but BMID billed more match to RCO than originally proposed. The PCSRF 2015 project funds were spent within the contract period.
