The Nooksack Tribe will restore instream habitat in the South Fork Nooksack River at RM 9.9, near Acme, Whatcom County.  The goal is to address South Fork Nooksack chinook limiting factors of lack of key habitat, low habitat diversity, and high temperatures.  Specifically, this project will construct 8 log jams in a 0.1-mile segment of the South Fork.  Log jams are designed to: (1) increase number and depth of pools for holding and rearing; (2) increase habitat unit diversity and quantity of complex wood cover in the low-flow channel; and (3) create temperature refuges.  The project is  the third of three phases of restoration in the broader Downstream of Hutchinson reach (RM 9.6-10.2), with the first (9 log jams) and second phases (10 log jams) constructed in 2012 and 2014, respectively.  This project is designed to benefit ESA-listed chinook, but it will also benefit ESA-listed steelhead and bull trout; coho, chum, riverine sockeye, and pink (odd- and even-year) salmon; and cutthroat trout. South Fork Nooksack early chinook are essential for ESU recovery, but abundances are critically low and immediate action is necessary to ensure population persistence.  This project implements high priority actions in a high priority reach of the South Fork.  Given the adjacent landownership, Whatcom Land Trust and Whatcom County Parks, the reach presents a unique opportunity to restore habitat and habitat-forming processes in a relatively unconfined reach in the lower South Fork.
