Description    


This grant by the Stillaguamish Tribe to construct 5 new logjams, purchase wood for a 6th ELJ, and repair and enhance 3 other large wood structures damaged by flood waters, in the North Fork Stillaguamish River watershed. The North Fork begins in the Cascade foothills of Skagit County and flows westerly to Arlington. The goal of this project was to create places for Chinook salmon to rest, feed, and hide from predators as they move through the river system. This project also partially funded an ELJ placement prioritization assessment (Attach. #18), analyzing data including aerial, LIDAR, infrared photography and proximity to associated acquisition and restoration projects and identify strategic ELJ locations. Three engineered log jams were placed to direct flow into remnant side channels at Hazel and downstream of French Creek and three jams were placed to split flow at the apex of a mid channel bar downstream of Hazel and downstream of French Creek. Repairs were made to the large log cribwall structure at the Steelhead Haven landslide twice during the life of this grant as well as cabling additional wood to two structures built earlier that needed some additional support. One of the critical factors limiting Chinook populations is the lack of large, deep pools where fish can rest during upstream migration and rear after emergence from the gravel. The log jams aid in the creation of quality pool habitat for holding and juvenile rearing as well as providing a lot of surface area for primary production and the capture of nutrients. New forest practice rules that protect channel migration and riparian condition are expected to provide a long-term source of wood to the river. This project provides short-term benefit while the watershed recovers.

Project Benefit    


This project improved instream morphology in several locations where jams were placed. Pools have formed and channels split for a more braided network. Adult and juvenile fish are using the structures including Chinook.
