This project will replace an unimproved low-water road crossing at Masterson Road with a bottomless, stream simulation culvert to restore fish passage and protect aquatic habitat in Noyes Valley Creek, a tributary to the East Fork Scott River. Noyes Valley Creek provides seasonal spawning, rearing, and migration habitat for ESA-listed coho salmon and other native salmonids and has been habitat typed by the Siskiyou Resource Conservation District (SRCD) as recently as 2023. Currently, the creek flows directly over a dirt road surface during winter and early spring runoff, forcing vehicles to drive through the active channel and creating shallow, unstable passage conditions for fish. The proposed project will span the active channel, maintain natural bed and hydraulic conditions, and accommodate sediment and debris transport, improving aquatic organism passage while reducing roadway maintenance and safety concerns.
