Site Comments: None

Survey Date: Jul 13, 2011

Survey SEA11-GLH13

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: No

Step Pools: No
Construction Year:


Site Observations:

  1. None of this type

Comments: No traps were set as stream is already in the AWC. 100+ juvenile salmonids observed upstream and downstream of pipe. Stream channel has heavy vegetation making stream gradient impossible to shoot, however it would apear to be at or near 0% as stream is flatwater throughout with very small step riffles aproximately every 150 to 200 feet. Nearly continuous pool systems.
