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 summer 2001 and 2002. The purpose of the project was to provide baseline inventory information on sockeye spawning habitat which could be used to identity spawning areas for management protection. Project objectives included: locating and georeferencing sockeye salmon spawning areas; developing a Geographic Information System (GIS) database that included maps of spawning habitat and physical lake characteristics, including locations freshwater springs during summer and winter; collecting continuous water temperature data at both spawning and control sites. This two-year study was completed in spring 2003. This report summarizes the methodologies used, project results, and makes recommendations about protection for priority spawning sites.
