The Nooksack Tribe restored instream habitat in the South Fork Nooksack River, RM 11.4-12, Whatcom County, to address South Fork (SF) Nooksack chinook limiting factors of lack of key habitat, low habitat diversity, and high temperatures. Specifically, this project constructed 20 log jams in a 0.6-mile river segment, as part of the first of two phases of restoration planned in the broader Nesset reach (10.9-12). Log jams were designed to: (1) increase number and depth of pools; (2) increase habitat unit diversity and quantity of complex woody cover in the low-flow channel; (3) increase availability of temperature refuges; and (4) improve incubation success and flood refuge habitat by improving connectivity of floodplain and floodplain channels. Other species benefitting are ESA-listed steelhead and bull trout; coho, chum, riverine sockeye, and pink salmon; and cutthroat trout. SF Nooksack early Chinook are essential for ESU recovery, but abundances are critically low. This project implemented high priority actions in a high priority reach. The adjacent landownership, Whatcom Land Trust and Whatcom County Parks, through the upper portion of the reach presented a unique opportunity to restore habitat and reconnect floodplains in a relatively unconfined reach in the lower South Fork. The reach is also expected to be heavily used by Chinook returning to the Skookum hatchery (two miles upstream) as part of the South Fork Nooksack Chinook population-rebuilding program.
