GIS data layers are available as ESRI personal geodatabases, compatible with version 10.1 and later, as well as in zipped shapefiles. Point features, where available, have been generated from the most recent HydroBase database. Data coordinates are in the UTM Zone 13 (NAD 83) projection. Polygon and other layers have been collected from other sources. Features generated from HydroBase contain only the minimum attributes for the data type.
