Overall Fish Passage Rating: Gray

Tidal: Yes
Backwatered: No

Construction Year:


Site Observations:

  1. Structural Problem
  2. Mechanical damage or joints parting
  3. Road bank erosion

Comments: This information was gathered as part of the joint reconnaissance level project between the ADF&G Habitat Division and the Fish Passage Assessment Project on Adak Island. Due to time constraints full site assessments were not conducted, but base line information was collected. Culverts deteriorated and falling apart. Adult pinks observed upstream and downstream of culvert. C2 appears to be collapsed and C1 appears to be over 1% gradient. Creek empties into Clam Lagoon directly downstream of outlet. Road erosion at outlet.
