Summary Information
Fish Passability 0.9
Fish Passage is an area of concern for this site.
plugged & crushed problems. Note: a guy backed up a truck ~1/4 mile to tell me how bad this culvert floods the road in the spring. He really wants it replaced like the one upstream.
A future visit to this site is recommended. check status of culvert
