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 empties into Clam Lagoon downstream, coho caught in upstream and downstream trap. Creek will be nominated to AWC. Culvert maybe tidal, but lack of deterioration suggests that it is not, but may get tidal push back.
