Legal Description: C039S064E12
Region: Southeast
Road Name: Glacier Highway

Datum: NAD83
Quad Name / ITM: Juneau C-3
AWC Stream #:
Stream Name: Strawberry Creek tributary

Elevation:

Site Comments: None

Survey Date: Jul 01, 2011

Survey SEA11-GLH08

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. Road Fill (pushed off road by grader)

Comments: No traps set as stream is already in the AWC. Pipe not embedded, substrate at inverts likely road grade fill flowing in, quickly drops down to metal ~4 feet into pipe. Upstream very mechanically influenced, ditch drain adjacent to field and gravel lot. Both upstream and downstream drain or flow through a muskeg/bog system.
