Summary Information
Fish Passability: Barrier at Most Flows
Is a future visit to this site recommended? Yes, Road is impassible, swamp looks blocked/still flowing water.
Were any non-native species observerd at this site? Yes, Spotted knapweed.
Site Comments: There is another culvert before this one that has been torn out of the road, making this road even more impassible along with downed trees. The other culvert has been recorded as a new culvert location.
