Site Comments: None
Survey SEA11-MGR01
Project Supervisor: Gillian O'Doherty, Alaska Department of Fish and Game
— Anchorage, AK
Observers: Mark Eisenman, Jason Olds
Overall Fish Passage Rating:
Tidal: No
Backwatered: No
Step Pools: No
Construction Year:
Site Observations:
- Outfall height red
- Culvert gradient gray
- Debris Flow
Comments: No fish data recorded, no traps set as stream is already in the AWC. Stream begins to braid quickly upstream after end of pipe so downstream widths were used. Old beaver activity in area. Majority of flow is through C2.
