Arizona Dams (1996)

This dataset provides a locational map of 75,187 dams in the conterminous United States. The National Inventory of Dams was originally developed by the U.S. Army Corps of Engineers and the Federal Emergency Management Agency. It was developed to track dam related problem areas. This database shows the age of the dam, number of people living downstream, and some inspection information. The dam inspection data also includes location information (such as latitude, longitude and nearest town), a description of a dam's size, reservoir capacity, the owner and the regulatory oversight agency. For distribution with BASINS v.2.0, the data layer was prepared in Arcview shape file format.

Intended use of data: This data set was prepared to support the U.S. EPA BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) System. The dam point coverage provides Geographic Information System GIS) applications with a valuable data layer for base mapping of dam locations. These locations are used in numerous types of analysis, e.g., stream network analysis, hydrologic flow.
