* NOTE: The Chinook redd maps include all visible redds, both new and old. The GIS files for the 2004 Chinook spawning season represents the approximate area used through 11-16-2004. In the past field crews mapped each redd but time and budget restrictions have reduced the effort for Fall Chinook, to mapping the perimeter of redds only. The Chum redd maps only show new redds and individual GIS points are taken for each redd.
