Summary Information
Fish Passability 1
Fish Passage is an area of concern for this site.
Yes, the culvert is larger than 100 feet long so it might be a barrier to fish passage.
A future visit to this site is recommended. The apron on the inlet is above the stream grade and has created a small upstream pond. Also the culvert is too long and may be a fish passage barrier.
These non-native species were observerd at this site: Spotted Knapweed
