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 is on an unused runway access road on the opposite side of the active terminal. Creek is part of the airport drainage system and parallels Sweeper Creek. It is separated by a large earthen dike that runs the length of the drainage area. Site C99, Sweeper Creek is only a few hundred feet away down the road. Water surface fairly flat through culvert, but only one 4 foot culvert found at site. Airport drainage pump station downstream.
