  1. California’s North Coast Region GIS Layers Lorri Peltz-Lewis U.S. Bureau of Reclamation Streamflow and Water Availability Estimates in Ungaged Streams

  2. Watershed Basin Characteristics: Total Drainage, Contributing Drainage, Non-Contributing Drainage, Perimeter, Shape Factors, Effective Width, Compactness, Elongation, Relief, Relative Relief, Total Stream Length, Main Channel Length, Channel Slope, Basin Slope, Basin Length, Drainage Density, etc. Geospatial Data Layers Reviewed Here: National Elevation Data (NED) or Digital Elevation Model (DEM) National Hydrologic Database (NHD) Elevation Derivatives for National Applications (EDNA) Watersheds - CALWATER Streamflow and Water Availability Estimates in Ungaged Streams

  3. National Elevation Data (NED) Seamless raster elevation database Combination of 10 & 30 m – final currently 30 m – future will be 10 m. Processing to eliminate merge problems Digital Elevation Model (DEM) Raster elevation database 10 & 30 m data files Tiled by quadrangle Others: LIDAR, SAR, RADAR, etc. Streamflow and Water Availability Estimates in Ungaged Streams
