Survey SEA11-SPL01

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

Overall Fish Passage Rating: Gray

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Constriction ratio gray
  2. Culvert is too short
  3. Hydraulic flows exceeded capacity
  4. Culvert gradient gray
  5. Outfall height gray

Comments: No fish observed or traps set as stream is already in the AWC. Pump structure at outlet pool. Large outlet pool, possibly dredged for pump.
