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. Site electroshocked. Threespine sticklebacks caught. One larger fish was observed, but not identified, most likely a Dolly Varden. Lots of sedimention and vegitation growth upstream and downstream from crossing.
