This is the second of two technical notes describing work done at the request of the Regulatory Branch and Planning Division of the U.S. Army Engineer District, Alaska, as part of a feasibility study for the potential development of a harbor at the head of Akutan Bay on Akutan Island in the Aleutian Island chain. Wakeley, Noble, and Bishop (2001) described the background of the project, alternative harbor designs, vegetation and soils, and the delineation of wetlands on the site. A technical report by Dunbar, Corcoran, and Murphy (2001) gives results of a geologic and hydrologic assessment including the predicted impacts of harbor construction on local ground- water flow and salinity. The purpose of this technical note is to describe the topographic survey that was conducted in support of the aforementioned studies, and the use of those data to develop a digital elevation model and detailed topographic map.
