This report is a follow-up to an earlier volume (Gottesfeld et al. 2002) which was prepared as part of the Skeena Watershed Fish Sustainability Plan process. The earlier report, Conserving Skeena Fish Populations and Their Habitat, presents an overview of the biophysical features of the Skeena Watershed, the important fish populations of the Skeena, the nature and history of resource development and a brief overview of the socioeconomic status of the watershed. The earlier report identified the eleven subwatersheds with the most productive fish habitat and most important fish populations. Rather than issuing a supplementary volume, we decided to expand and update the first volume to include all areas of the Skeena.
