Dutch Bill Creek Market Street Weir Repair Fish Passage Improvement Project
This project will design and permit repairs to a failed weir at the site of the original 2009 Dutch Bill Creek Barrier Elimination Project near Camp Meeker, restoring fish passage for endangered coho salmon and threatened steelhead trout to upstream spawning and rearing habitat in this Russian River tributary in Sonoma County.

Iron Horse Vineyards Dam Removal Project
This project removed an obsolete flashboard dam on lower Green Valley Creek at the Iron Horse Vineyards property in Sonoma County — the second of two remnant dams identified as the primary fish passage barriers in the lower creek. Approximately 35 cubic yards of concrete were excavated, banks regraded, large wood habitat structures installed, and willows planted. Removal opened 35 miles of upstream aquatic habitat, benefiting federally endangered Central California Coast coho salmon and threatened steelhead in a watershed that harbored the last documented wild Russian River coho prior to captive broodstock recovery efforts.

Upper Green Valley Creek Fish Passage Project
This project replaced a severely undersized, failing private road culvert on Upper Green Valley Creek — a Russian River tributary in Sonoma County — with a 15-foot bottomless arch culvert and a 157-foot step-pool roughened channel with boulder weirs for grade control. The culvert had blocked coho access under all flow conditions. The project opened 0.9 miles of spawning and rearing habitat, and post-construction surveys detected 136 steelhead young-of-year upstream of the site, benefiting federally endangered Central California Coast coho salmon and threatened steelhead.
