North Fork Nooksack early Chinook are considered essential for ESU recovery, but natural origin productivity and abundances are low. This project constructed 14 engineered log jams and removed 150 feet of riprap in the North Fork Nooksack River, Wildcat Reach (RM 54.4-54.8), to address limiting factors of channel instability and low habitat diversity in the reach. The Nooksack place name for the North Fork Nooksack River is Xwqélém, which translates as "always-dirty water", a reference to its glacial origin; the project reach is just downstream of Na-e-wha-quam, the camp at the mouth of Canyon Creek. The Wildcat reach ranked highest among North Fork reaches in terms of potential restoration benefit. This project was the third and final phase of a larger project designed to: (1) increase the low-flow connectivity and habitat diversity of Wildcat side channels and other floodplain habitats; and (2) to increase channel stability and protect and encourage growth of maturing forested islands in the main channel. The project is expected to improve chinook spawning-incubation success by increasing the availability of stable spawning habitat in floodplain channels and by restoring the more stable island-braided planform historically evident in the North Fork. Previous SRFB grants for this reach include: 09-1682: NF Nooksack Wildcat Reach Feasibility and Design; 10-1810: NF Nooksack Wildcat Reach Restoration: Phase 1; and 11-1572: NF Nooksack Wildcat Reach Restoration Phase 2.
