Survey Date: Jun 07, 2011

Survey SEA11-FCR01

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

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Culvert gradient red
  2. Constriction ratio gray

Comments: Downstream 2 log wier gradient control structures. Culverts likely embedded at one time, substrate in both pipes partially pushed out. Culvert 1 has substrate at inlet and culvert 2 has substrate at outlet, both insufficient depth. Upstream habitat high quality despite reported falls barrier downstream. Sighted a fish upstream from culvert in a pool, likely a Dolly. Upstream habitat high quality despite reoprted falls barrier downstream.
