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 submerged. Unable to identify the type of structure here, but most likely a wooden box culvert like many of sites in the area that date back to WWII. Lots of Dolly Varden Char caught upstream and downstream of crossing.
