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 part of the airport drainage system. Airport pump station down stream from outlet, but not operational at time of visit. Could not see through culverts. Strong smell of diesel fuel when sediment was disturbed in creek upstream. No fish observed while at site.
