Summary Information
Fish Passability: Barrier at High Flows
Is a future visit to this site recommended? Yes, No flow through the culvert. It also is in poor condition.
Were any non-native species observerd at this site? Yes, Knappweed, mullein.
Site Comments: Representative reach not taken because there is no flow and sream channel is dry.
