Overall Fish Passage Rating: Black

Site Observations:

  1. Woody Debris
  2. Inlet perch

Comments: At the time of the survey the channel was dry and was not connected to any water network. The culvert was dry and the inlet contained a large woody beaver dam. Approximately 10' dwst was one single isolated pool which did have some landlocked fry. The dry gravel channel was a direct trib to the Susitna River with the confluence about 200' dwst of the culvert. Culvert was a new site found so no FID# was assigned.
