  1. Data Sources for GIS in Water Resourcesby David R. Maidment and David G. TarbotonGIS in Water ResourcesFall 2005

  2. Geospatial One-Stop http://www.geodata.gov/gos

  3. Google Earthhttp://earth.google.com/

  4. Watersheds of the US 2-digit water resource regions 8-digit HUC watersheds

  5. Hydrologic Unit Code Watersheds ~ 2000 for US, about the size of counties

  6. Watershed Hierarchy Digit # 2 4 6 8 HUC 10 12 EDNA Available In Progress

  7. National Program by USGS and USDA (NRCS) Boundaries for 10- and 12- digit watersheds First cut is by automated delineation from NED Hand checked and edited Watershed Boundary Dataset 10-digit watersheds

  8. EPA River Reach File 1 (RF1)

  9. BASINS - Integrating GIS and Water Quality Modeling Data Cartographic Monitoring Loadings Tools Target Assessment Data Mining Reporting • Models • HSPF - NPSM • QUAL2E • TOXIROUTE • Post-Processors Target Assess DM Decisions Watershed Management . TMDL . Source Water Protection . Stormwater State and Local Data

  10. River networks for 8-digit HUC watersheds http://nhd.usgs.gov/

  11. Lower West Fork, Trinity River Basin HUC = 12030102

  12. NHD River Reaches 412 River Reaches In Upper West Fork of Trinity Basin

  13. River Reach CodesUsed for river address locations ReachCode = 12030102000151 ReachCode = 12030102000005 Location 0.392 on Reach 12030102000005 Segment# HUC#

  14. Digital Elevation Model with 1 arc-second (30m) cells Seamless in 1° blocks for the United States 10 billion data Derived from USGS 1:24,000 quadrangle sheets Get the data: http://seamless.usgs.gov/ National Elevation Dataset http://gisdata.usgs.net/ned/

  15. Digital Elevation Model (DEM) 720 720 Contours 740 720 700 680 740 720 700 680
