Survey SEA11-GRR01

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. Constriction ratio gray
  2. Culvert gradient gray
  3. Improper bedding
  4. Road bank erosion
  5. Structural Problem
  6. Culvert is too short

Comments: Culvert 1 Set to take most of flow. Upstream Salmonids observered. Steel erosion control on Right Bank looking downstream. Excellent Fish habitat up/down stream. Pipes too short. Circular Pipe upstream broken off from undercutting; needs replacement, but still allows for flows. Road fill falling into creek. At low water culvert 2 would take all flow and remain backwatered.
