|The Nimpkish River Watershed supports five Pacific salmon species including Coho(Oncorhynchus kisutch), Chinook (O. tshawytcha), Sockeye (O. nerka), Pink (O. gorbuscha) and Chum (O. keta). Also, significant populations of other sport fish including Cutthroat Trout (O. clarki), Rainbow Trout/Steelhead (O. mykiss) and Dolly Varden (Salvelinus malma) also exist in the Nimpkish River system (FISS, 2008). Yookwa Creek itself is known to support populations of Coho salmon, Cutthroat Trout, Dolly Varden, as well as Rainbow Trout and Steelhead. Because of this high value multi-species resource, and the impacts from historic logging activity, Yookwa Creek has been targeted for fisheries rehabilitation activities by Western Forest Products with funding from the Forest Investment Account.|
Yookwa Creek was identified as a priority for fisheries rehabilitation by the Nimpkish Watershed Salmon Recovery Plan. M.C. Wright & Associates and Integrated Watersheds Ltd. were contracted by Western Forest Products in 2007 to develop a prescription for restoration works within Yookwa Creek. The lower 2 km of Yookwa Creek consists of an unstable alluvial fan, and restoration projects to date have not resolved the ongoing impacts within lower Yookwa Creek. Fish production will continue to decline if nothing is done to mitigate the major issues in lower Yookwa Creek. To address the ongoing impacts to fish and fish habitat, a more aggressive approach to restoration of lower Yookwa Creek will be required. The proposed restoration works will ultimately benefit fish and fish habitat in both Yookwa Creek and the Sebalhall River. The site was assessed from Oct/07 to Jan/08 for fish habitat, channel morphology, disturbances, and restoration opportunities.
