Abstract This map layer portrays major dams of the United States, including Puerto Rico and the U.S. Virgin Islands. The map layer was created by extracting dams 50 feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more, from the 79,777 dams in the U.S. Army Corps of Engineers National Inventory of Dams. This is a replacement for the April 1994 map layer.
Purpose These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

Maintenance and Update Frequency In the online National Atlas of the United States Map Maker, at scales smaller than 1:4,850,000 the data is thinned for display purposes. For scales between 1: 4,850,000 and 1:22,000,000, dams are only shown if they have a height of 500 feet or more, or a normal storage capacity of 50,000 acre-feet or more, or a maximum storage capacity of 250,000 acre-feet or more (1280 dams). At scales smaller than 1:22,000,000, dams are only shown if they have a height of 5000 feet or more, or a normal storage capacity of 500,000 acre-feet or more, or a maximum storage capacity of 2,500,000 acre-feet or more (290 dams).

Data Quality Information

Logical Consistency Report This file contains those dams from the National Inventory of Dams with a height of 50 feet or more, or with a normal storage capacity of 5000 acre- feet or more, or with a maximum storage capacity of 25,000 acre-feet or more. Dams outside of the 50 States, Puerto Rico, and the U.S. Virgin Islands are not included, nor are dams for which there is no positional information in the National Inventory of Dams.
Completeness Report Data completeness reflects the contents of the National Inventory of Dams at the time the Shapefiles were created.

Process Step
Process Description The full National Inventory of Dams (NID) was downloaded from the NID web site in shapefile format and loaded into ArcView. Using an ArcView query, major dams were selected and placed in a new shapefile. Major dams were defined as dams with a height of 50 feet or more, or with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more. (The International Committee on Large Dams considers dams over 50 feet to be large dams. The USGS Water Resources Division considers large reservoirs to be those with a normal storage capacity of 5,000 acre-feet or more, or with a maximum storage capacity of 25,000 acre-feet or more.)Because the text fields contained entries in a mix of formats, some in all capitals and some in capitals and lower-case, all text entries were changed to all capitals. Some dams were missing county attribute values. The appropriate values were determined by comparing the dam locations to the Atlas-Cnty file. One dam was deleted because it was described as being in Maryland but had coordinates that placed it in Virginia. Invalid values for owner type (197 records), dam type (10 records), and year completed (3 records) were changed to blanks to indicate that the values are unknown. The attribute Purposes contained some invalid codes; these were removed but valid codes and duplicate codes were retained. Thirty-nine records contained a value of -9.9 for Nid_height. The appropriate value for each record was determined by looking at the dam height, structural height, and hydraulic height values in the source data. One invalid value for hazard was changed to U to indicate that the hazard potential is unknown. The shape file was converted to an ArcInfo coverage and then converted to NAD 83 for display purposes. The result was then converted back to shapefile format.
