DESCRIPTION
South Fork Nooksack early Chinook are considered essential for ESU recovery, but abundances are critically low and immediate action is necessary to ensure population persistence. This project advanced project implementation in the lower South Fork Nooksack, which is the highest priority geographic area for restoration for the South Fork chinook population. Specifically, this project developed construction-ready designs, conducted flood risk analysis, and prepared permits for construction of engineered log jams designed to form deep pools with cover in the South Fork Nooksack River downstream of Hutchinson Creek (RM 9.5-10.1). Log jams were designed to: (1) Increase habitat diversity (i.e. increase quantity of complex wood cover in low-flow channel, increase habitat unit diversity); (2) increase key habitat quantity (increase number and depth of pools for holding and rearing, number of pool tailouts for spawning); (3) increase channel length; and (4) increase floodplain connectivity. The project reach ranks 9th of 25 South Fork project areas in recent guidance materials; projects in 5 of the 8 higher ranking reaches are complete or underway. The reach also presented a unique opportunity to work in a realtively unconfined reach in the Lower South Fork where the channel can more naturally respond to log jams.
