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. Creek comes out of culvert and cascades over rocks downstream for about 10 to 20 feet. Marginal habitat upstream, but could be Dolly Varden.
