Summary Information
Fish Passability 0.9
Erosion is an area of concern for this site. Yes, eroding material washing in and culvert condition suspect.
A future visit to this site is recommended. Culvert may be disfunctional/plugges as no flow and cracked at inlet. *Note: Structure material-ceramic? Cracked, tile?; and too deep to tell if plugged or crushed.
