Survey MSB11-PRK09

Project Supervisor: Gillian O'Doherty, Alaska Department of Fish and Game — Anchorage, AK
Observers: John Greuey, Abraham Gioffre

Overall Fish Passage Rating: Green

Tidal: No
Backwatered: Yes

Step Pools: No
Construction Year:


Site Observations:

  1. None of this type

Comments: Marshland upst and dwst so no stream widths or gradients collected. Water surfaces throughout the pipes had very minimal change and was still so site was labeled backwatered. Culverts connect two flat slough flows within a marsh area.
