Comments: Noticible deterioration inside of culvert at outlet. Large pieces of the culvert wall have rusted away. Outlet does have accumulated large substrate. Gradient does look to be an issue with this culvert and is most likely red. Adult pinks were observed swimming up culvert, but there is a low water depth issue near inlet.
