Chinook Salmon ESU, Upper Klamath and Trinity Rivers - NOAA [ds799]

This dataset is intended to provide GIS users with data for creating maps that depict the ESU/DPS boundary as well as the historical structure of the population. The data are based on the most recent species description found in agency regulations and published in the Federal Register. The polygons illustrate the location and extent of freshwater spawning areas occupied currently (the ESU/DPS boundary) or historically. However, these data DO NOT constitute a legal boundary or definition for this DPS. These data are based on the most recent species description found in agency regulations at 50 CFR 17.11, 50 CFR 223.102, and 50 CFR 224.101. Please see Supplemental Information for more details regarding this dataset. (http://www.westcoast.fisheries.noaa.gov/maps_data/Species_Maps_Data.html )
