United States Dam Locations with USGS Hydrologic Unit Codes (HUC) and other descriptive attributes

Dataset consists of two components, stored as separate ESRI-standard Shape Files:

1) Polygon Shape file containing 2103 watershed regions for the continental United States, categorized by USGS Hydrologic Unit Code (HUC-8).

2) Point Shape file containing the location
coordinates and eighteen descriptive attributes for
75,100 dams within the continental United States. One of the attributes is the HUC-8 code corresponding to the watershed that bounds the dam location.
Source for dam locations:

U.S. Army Corps of Engineers, 1996. National Inventory of Dams, National Water Control Infrastructure, CD-ROM (Washington, D.C.: U.S. Army Corps of Engineers and Federal Emergency Management Agency).

The dam locations are derived from the National Inventory of Dams data set generated and maintained by the United States Army Corps of Engineers.
