The goal of this proposal is to work toward achieving the Chehalis Basin Recovery Plan Tier 1 goal to correct all fish barriers in the basin. The project objective is to remove two undersized culverts under the West Satsop D-Line on two unnamed tributaries to the West Fork Satsop and provide spawning and rearing habitat for coho, Chinook, chum, steelhead and cutthroat trout. Removing these culverts will reinstate the natural biological and hydraulic functions of the stream. Removing these barriers may also provide additional grazing habitat for bull trout during late fall and winter months. This restoration project will correct two fish barrier culverts on separate tributaries to the West Fork Satsop River on a Weyerhaeuser main haul road. Site 1 is on an unnamed tributary to a larger unnamed creek on which Site 2 is located. Site 1 consists of a squashed pipe with a six foot span and five foot rise. This will be removed and replaced with a pipe arch culvert. The Site 2 tributary flows into the West Fork Satsop River approximately half a mile downstream. The existing culvert is an undersized pipe arch which will be replaced with a bottomless arch. Correcting both of these undersized barrier culverts will open access to 0.81 miles of potential habitat at Site 1, and 2.8 miles at Site 2, for a total of 3.61 miles. The primary species that will benefit are Coho, Cutthroat Trout, Chinook, Chum, and Steelhead.
