Inventory and Mapping of Sixmile Lakes Sockeye Salmon Spawning Habitat
Abstract
The Alaska Natural Heritage Program (AKNHP) provided services to map the extent of habitat spawned upon by sockeye salmon (Onchorynchus nerka) in Upper and Lower Sixmile Lakes on Elmendorf Air Force Base (EAFB), Alaska, during sumner 2001. The purpose of this project is to provide baseline inventory information on sockeye spawning habitat which may be used to determine the carrying capacity of spawning in this drainage, to plan future limiting habitat studies, and to identify spawning areas for management protection. Project objectives included: locating and georeferencing sockeye salmon spawning areas; calculating potential production of spawning habitat; developing Geographic Information System (GIS) map layer of spawning habitat; mapping 3-dimensional spawning depth profiles; mapping locations of freshwater springs during winter; collecting continuous water temperature data at both spawning and control sites. This is a two-year study, and will be completed in spring 2003. This report summarizes the methodologies used during the 2001 field season and preliminary results are presented.
