Summary Information
Fish Passability 0.5
Fish Passage is an area of concern for this site.
Culvert is broken off at the inlet as is disrupting flow
A future visit to this site is recommended. May want to revist to determine severity of broken culvert
These non-native species were observerd at this site: Glossy Buckthorn
