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. Deep outlet pool and nice habitat upstream. If adults can make it above culvert likely anadromy continues for quite a ways. Lots of healthy looking juvenile coho caught in outlet pool.
