West Coast Stream Attributes for Salmon Intrinsic Potential

Metadata Updated: March 8, 2024

The dataset was built using the U.S. National Hydrography Dataset Plus (NHDPlusV2, 1:100,000 scale) stream network and value-added attributes (VAA), the U.S. National Elevation Dataset 10-meter digital elevation model, the National Oceanic and Atmospheric Administration National Water Model recurrence interval flows, the United States Geological Survey (USGS) level 4-scale Hydrological Unit Code boundaries, and the U.S. Environmental Protection Agency Level III ecoregion boundaries. Reaches in this dataset vary in length up to 200 meters. Reaches with unknown flow direction were removed from the original stream network.
