GIS Boundaries of NASQAN Watersheds

There are 2 zipped and tarred files of the watersheds sampled by the U.S. Geological Survey NASQAN between 1996-2000. The first contains a site coverage and the complex watershed coverage. The second has shape files that include both individual watersheds and a single polygon shape file of the areas above each of the sites. Both data sets include the watershed areas in Mexico and Canada and are documented.
