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. Unidentified fish observed at outlet, likely Dolly Varden char. There is another culvert sitting in the middle of the creek about 10 feet upstream from culver inlet. Looks like it might have been placed there to allow the road prism for this old road to be expanded. It is a 4' circular CSP as well and is not perched. Creek flows down into Clam Lagoon and passes through culvert C8. Downstream portion of this creek will be nominated to AWC. Water surface looks flat through culvert, maybe backwatered, does not appear to be constricted, same with upstream culvert. Neither appear to be a barrier, but road is unused and there is no need for these culverts.
