Select State to View Dams, Hatcheries or Watersheds (Hydrologic Unit Codes or HUCS)

Washington Idaho Oregon

The data points used in these maps came from various sources and use various projections (which were converted by ArcView). The states, cities, HUCS (originally from USGS) and streams are from nationalatlasgov, and the dams and the hatcheries points are from streamnet. These maps are in 1:2,500,000 scale. Not all hatcheries in our database appear on this map. For a complete list of all hatcheries in our anadromous hatchery database see our Hatchery Metadata or use the Query by Hatchery instead of this map.
