Summary Information
Fish Passability 0
Fish Passage is an area of concern for this site. higher flows probably allow better fish passage; the culvert is only slightly perched and fish can still pass but if it becomes more perched it will become a fish passage barrier
A future visit to this site is recommended. Fish passage
