The Billy Creek project removed a perched, undersized
culvert that was blocking fish passage into the upper part of Billy Creek,
and replaced it with a modular concrete bridge. The project also placed
over 100 logs, and 30 boulders, at 20 sites to improve coho habitat below
the new bridge. Coho were seen spawning above the bridge the first winter
