DESCRIPTION
The North Fork Nooksack (XWQÉLÉM) Farmhouse Reach Restoration Project is a multi-phase, reach-scale, engineered log jam (ELJ) project being implemented by the Tribe to address North/Middle Fork Nooksack chinook limiting factors of high channel instability and low habitat diversity. North/Middle Fork Nooksack early chinook are essential for ESU recovery, but productivity is critically low. This project implements high priority actions in a high priority reach of the North Fork. Given the forestry-dominated adjacent land use and relative lack of channel constraints, the Farmhouse reach presented an important opportunity to restore habitat-forming processes.
As part of the Farmhouse Phase 2b Restoration Project, the Nooksack Tribe constructed ELJ's and large wood structures to restore in-stream habitat in the North Fork Nooksack River, RM 47.9 - 48.2, near Kendall in Whatcom County. Specifically, this project constructed 16 engineered log jams (ELJ’s) and 3 large wood structures in the summer of 2016 and interplanted conifers in suitable areas to restore floodplain forest.
Phase 2b was designed to build stable wood structures that meet the project goals and habitat objectives while avoiding unwanted impacts to adjacent landowners. The locations of the structures were adjusted using sequential hydraulic modeling iterations to promote hydraulic complexity which in turn will create habitat, sort spawning gravels, promote floodplain connectivity and off-channel habitat, and encourage formation of stable mid-channel islands with associated potential for mature forest establishment.
