- Abstract:
-
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.
Extracted for Arizona & 25 mile buffer
- Purpose:
-
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.

-
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.

- Process_Description:
-
Using the ADD EVENT THEME function of Arcview, an Arcview shape
file showing the locations of the dams is created based on the
latitude and longitude coordinates associated with each dam site
in the dams database.
For distribution with BASINS 2.0, the data layer was divided by EPA
regions (i.e. distribution by CD). Other form of data distribution
(e.g. by cataloging unit) is available through the web
