Site Comments: U/s and d/s are wetland.

Survey Date: May 20, 2009

Survey PRK09-BRG01

Project Supervisor: Gillian O'Doherty, ADFG
Observers: Heidi Zimmer, Ben Histand

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools:
Construction Year:


Site Observations:

  1. Culvert gradient red
  2. Shallow fill; inadequate roadfill volume above culvert
  3. Culvert is poorly aligned

Comments: No CR because u/s and d/s are wetland. Possible depth barrier at low flow. **Updated site photos and fish capture information added from 9/30/16 site visit from Sampling Unmapped Streams in the MSB.
