Summary Information
Fish Passability 0
Fish Passage is an area of concern for this site.
Culvert is perched too high for any fish passage; this is the first/last culvert before stream reaches Lake Huron, so this may be considered a priority to reconnect upstream habitat
A future visit to this site is recommended. To determine if stream should be considered a priority
