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. Large amount of substrate inside culvert, uanble to identify culvert type, likely circular, pipe arch, or open bottom arch. Airport creek empties out into Kuluk Bay directly downstream. Adult pink salmon observed upstream and downstream of culvert.
