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. Culvert(s) submerged. Adult pink salmon observed upstream and downstream from crossing. Stream maybe constricted. Access has been blocked by an earthen berm and crossing is no longer needed.
