Description
This page is meant to act as an archival repository for previous versions of the statewide National Hydrography Dataset (NHD) which includes the Watershed Boundary Dataset (WBD) released by USGS. All data are presented in their original, unmodified format as downloaded from USGS. Be aware that the data do not come with a geometric network; directions for building the geometric network can be found in the text file on this resource page called "How to Create NHD Network".
