  3. Google Earth http://earth.google.com/

  4. USGS GIS data for Water http://water.usgs.gov/maps.html

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

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

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

  8. 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

  9. Watershed Boundary DataSet http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/

  10. WBD for Nebraska 2990 HUC12 watersheds of average area 39.3 square miles HUC12:HUC ~ 40:1 watersheds

  11. EPA River Reach File 1 (RF1)

  12. 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

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

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

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

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

  18. NHDPlus for a Portion of Oregon http://www.horizon-systems.com/nhdplus/

  19. NHDPlus Reach Catchments ~ 3km2 Average reach length = 2km 2.3 million reaches for continental US About 1000 reach catchments in each 8-digit HUC

  20. Slope Elevation Mean annual flow Corresponding velocity Drainage area % of upstream drainage area in different land uses Stream order NHDPlus Reach Attributes
