Summary Information
Fish Passability 0
Erosion is an area of concern for this site.
Erosion is due to undersized culvert and severe flooding of crossing during heavy rains. (Adjacent landowner offered pictures and videos)
A future visit to this site is recommended. Cuvert needs replacing. Crossing overtops road. Landowner claims it's a safety hazard.
