Survey Date: Aug 14, 2011

Survey SEA11-VNS01

Project Supervisor: Gillian O'Doherty, Alaska Department of Fish and Game — Anchorage, AK
Observers: Jason Olds, Charmagne Gutierrez

Overall Fish Passage Rating: Green

Tidal: No
Backwatered: Yes

Step Pools: No
Construction Year:


Site Observations:

  1. Culvert gradient gray
  2. Constriction ratio red

Comments: Headwall of unusual steel plate construction has long since ceased to function. Large outlet pool. No stream grade calculated as sightabillity is limited with dense foilage. Apparent even glide continuous upstream and downstream of culvert with near flatwater conditions.
