Fish Passage Site 10302267

Coordinates (dec. deg.): 58.45442°, -135.87398°
Legal Description: C039S058E32
Region: Southeast
Road Name: Glacier National Park Drive

Datum: NAD83
Quad Name / ITM: Juneau B-6
AWC Stream #:
Stream Name: Bartlett Cove tributary

Elevation:

Site Comments: None

Survey Date: Aug 14, 2011

Survey SEA11-GNP01

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

Overall Fish Passage Rating: Red

Tidal: No
Backwatered: No

Step Pools: No
Construction Year:


Site Observations:

  1. Outfall height red
  2. Culvert is poorly aligned

Comments: No stream calculated. Intentional fish barrier constructed at invert out as upstream is source of park water supply approximately 50 feet of invert in. Channel braids upstream and downstream of culvert to ditch adjacent road upstream and delta to confluence of Bartlett Cove downstream. In AWC below fish barrier structure so no traps were set or fish observed. Local biologist reports trapping above culvert numerous times without catching anything. Nearly right angle aproach.
