Survey UPDATE-1320

Project Supervisor: Gillian O'Doherty, ADFG
Observers: Mark Eisenman

Overall Fish Passage Rating: Red

Tidal:
Backwatered:

Step Pools:
Construction Year:


Site Observations:

  1. Hydraulic flows exceeded capacity
  2. Structural Problem
  3. Road Fill (pushed off road by grader)
  4. Mechanical damage or joints parting

Comments: Road was widened recently and culverts were not lengthened. Site visited in Sept 2017. Inlet and outlet submerged and partially buried. Water rolling up from outlet causing road bank erosion. Nelson road has been closed with the new Trunk Road spur to the west and a gated off of the frontage road by the Glenn Highway. Site possibly being removed and will allow limited access to the north end of the Palmer Hay Flats Refuge.
