The National Hydrography Dataset (NHD) is a national hydrographic data set which describes surface water resources in the United States. The Fox NHD-reach data represents a small portion of this extensive data resource. This data describes stream/river reaches in the entire Fox watershed (both Wisconsin and Illinois portions) and was created from the route.rch data in the Arc/Info coverage. Polyline M features were maintained in this version. For complete metadata for the NHD, visit http://nhd.usgs.gov/index.html

This data set was created to assist research at the Illinois State Water Survey.
