Survey Date: Jul 14, 2011

Survey SEA11-GLH17

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

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Outfall height red
  2. Constriction ratio gray
  3. Culvert gradient red

Comments: Fish observed upstream/downstream. Nice habitat upstream ~200 downstream to Auke Bay. Stream gradient calculated at 380 feet upstream of culvert beginning outside influence of culvert at 79 feet upstream for a total of 16.4 x mean OHW, beyond this point became too difficult with large woody debris in stream and foilage.
