Title
Salish Sea basin boundary [Washington (State)]
Description
Abstract The basin delineation was initially derived using standard watershed tools and DEM's (from NOAA). The computer generated watershed boundary was then manually edited via visual interpretation using topo maps, the DEM files and other watershed boundary maps (notably from the Sea Doc Society). The majority of the editing was in smoothing the original watershed boundary as the auto generated basin was far too detailed for the scale of the map. The smoothing process also removed the ‘raster' artifacts. For the Salish Sea map the intent was just to show the general boundary as a smooth line that visually follows the topography. Again, the emphasis was for an easy to understand cartographic representation of the basin at a fairly coarse scale, not for exact hydrologic analysis. Purpose For the purposes of this map & dataset, the Salish Sea was defined as including: Puget Sound, Desolation Sound (note, some BC definitions exclude Desolation Sound), Strait of Juan de Fuca (to the mouth of the Pacific Ocean), Strait of Georgia (which I defined as extending to Johnstone Strait). The Salish Sea polygon and corresponding Basin boundary files were derived for use at approximately 1:1,500,000 (e.g., Salish Sea Map, 2009, http://staff.wwu.edu/stefan/SalishSea.htm).
