The primary purpose of this project was to reduce the delivery of forest road-related sediment to Tenas Creek, Big Creek, and the Suiattle River. which are two important Spring Chinook spawning streams in the Suiattle River basin. Elevated sediment supply can affect aquatic habitat in a number of ways, including reducing pool depth, increasing redd scour and fill, and widening channels. Reducing sediment supply was expected to improve spawning and rearing habitat conditions for all species that use Tenas and Big creeks and the Suiattle River, including Chinook, pink, coho, steelhead, cutthroat, and native char. This project upgraded approximately 3.8 miles of forest road and decommissioned approximately 15.3 miles of forest road in the Suiattle River basin. Upgrading roads involves upgrading stream crossings, adding and upgrading drainage structures, cleaning ditch lines, and removing or stabilizing hazardous fill material. Decommissioning includes removing stream crossing and drainage culverts, installing water bars, and removing unstable road fill material.
