Watersheds are units for surface-water runoff and are broadly used to define the spatial extent of surface-water investigations and management programs. A standardized, digital data base of accurately and consistently defined watershed boundaries, or hydrologic units, has been developed to support water resources programs in Georgia. This new watershed boundary map is a cooperative effort of the Georgia Department of Natural Resources, the U.S. Geological Survey (USGS), the Georgia Geographic Information System Clearinghouse, and the Natural Resources Conservation Service (NRCS). Watershed boundary development also was coordinated with adjacent States, and with Federal Geospatial Data Committee efforts to create a National guideline for watershed boundary—or hydrologic unit—mapping. The map is complete and a digital copy may be obtained from the USGS, the Georgia GIS Clearinghouse, or the NRCS. A hard copy of the map and supporting report also is being produced by the NRCS and the USGS.
