Estimating Ephemeral Streams QGIS Layer Packages, Map Files, and Methods

This dataset was used to estimate total ephemeral stream length within the Coeur d'Alene, Fort Apache, and Menominee Reservations. It includes data that is publicly available through the USGS "The National Map" (USGS TNM Download v2.0), including NHDPlus High Resolution hydrography data, and Contour (1:24,000-scale) elevation data. It also includes geographic boundaries for the above mentioned Native American Reservations, as well as "eph5ha" raster data (Fesenmyer et al. 2021), which was used to approximate ephemeral stream locations. The remaining layers in the dataset include exported, site-specific NHDPlus hydrography data, and hand-digitized, estimated ephemeral streams, based on the eph5ha raster data. A map PNG of all three reservations is also included, as well as the map file used to create that map image. Lastly, a PDF of the methods used for this mapping project is also attached.
