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. Two culverts at site the inlet of C2 is buried, C1 is squashed, both culverts perched and piece of the outlet have broken off.
