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 look to be in a tidally influenced area. Constriction looks to be an issue. Lots of large sediment deposited at inlets. There is some substrate through the culverts. It looks to be naturally deposited, but not to a depth that would make the site embedded. Culverts show significant signs of deterioration.
