Digital Data Set of 14-Digit Hydrologic Units in Indiana

Prepared in cooperation with the Indiana Department of Environmental Management and
    the Indiana Department of Natural Resources, Division of Water.

A hydrologic unit is an area of land that can contribute surface-water runoff to a designated outlet point. As part of an initiative to create a nationally uniform hydrologic-unit data base, the U.S. Geological Survey and the Natural Resources Conservation Service, in cooperation with the Indiana Department of Environmental Management and the Indiana Department of Natural Resources Division of Water, created a Geographic Information System digital data set of 14-digit hydrologic units in Indiana. The digital data set consists of arcs and polygons defining hydrologic units in Indiana.

• To download a dataset for a particular 6-digit accounting unit or the entire state of Indiana, click on the format desired:

• Compressed SDTS files
• Compressed ARC/INFO export files

A free viewer for ARC/INFO* export files, called "dlgv32 Pro", is available for download at the website http://mcmcweb.er.usgs.gov/drc/dlgv32pro/.

Interactive Determination of 14-Digit Hydrologic Units in Indiana

To find a 14-digit hydrologic unit code, go to the Indiana Geological Survey's "GIS for Indiana" web site at the following link:

• http://igs.indiana.edu/arcims/statewide/
• From that page, click on the link named "CLICK HERE TO CREATE INTERACTIVE MAPS."
• Instructions to use the online maps can be found under the "HELP" button.
• The 14-digit codes can be found under the "Hydrology" map layer and are listed as "Watershed HUC14."
