Fish Passability 0.5
A future visit to this site is recommended. There is a significant pool at the inlet, which may be a flood hazard with the two undersized culverts during a highwater event. The area is surrounded by a low marsh floodplane that may mitigate that effect.
These non-native species were observerd at this site: Spotted Knapweed
