Summary Information
Fish Passability 0.5
Fish Passage is an area of concern for this site.
Yes, because culverts too short. Should be replaced with one larger culvert that is longer. Culvert R2 is also blocked so there is no flow through it. Plus alignment is not great.
A future visit to this site is recommended. Blocked
