The Stillaguamish Tribe of Indians partnered with the US Forest Service and Washington Department of Ecology to restore hillslope hydrologic processes altered by roads associated with the densely roaded South Branch and Crevice Creek subwatersheds in the upper North Fork Stillaguamish drainage. This project treated 13 miles of roads to reduce road densities and the risk of road failure that could lead to catastrophic sedimentation into South Branch, Crevice Creek, and downstream into the North Fork Stillaguamish mainstem. This work entailed varying levels of treatment depending upon risk failure. The project also included removing culverts,adding drainage dips, hardening drainage dips, removing side-cast material, and recontouring slopes by pulling back fills on nine miles of decommissioned road and four miles of road that access areas expected to be enhanced for late-successional reserve habitat within 20 years. Resident and anadromous fish which benefit from decreased sedimentation include Chinook, coho, pink, chum, steelhead/rainbow, sea-run/resident cutthroat, bull trout/Dolly Varden, and riverine sockeye. Expected benefits include increased survivability of eggs and juveniles, as reduced sedimentation improves the quantity and quality of spawning and rearing habitat. Benefits will be delayed but long-lasting as the roads revegetate and their influence on local hydrology lessens.
