Major Dams: Map Layer Description File

This map layer includes the locations of over 7,700 majors dams in the United States. The information in the map layer was provided by the U.S. Army Corps of Engineers (USACE). The original dam information came from the National Inventory of Dams (NID) which was produced by USACE in cooperation with FEMA's National Dam Safety Program. The full NID contains over 75,000 dams and is used to track information on the country's water control infrastructure.

Description:

Abstract:

This data set portrays major dams of the United States. The data set 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 75,187 dams in the U.S. Army Corps of Engineers National Inventory of Dams.

Purpose:

The digital data sets of the National Atlas are used to create electronic and hard copy maps that depict various aspects of the nation. The data can be used to conduct geographic analysis on national and large regional scales. The digital data will provide a basis from which future revisions of the atlas can be derived.

Supplemental_Information:

In the online, interactive National Atlas of the United States, 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 (1172 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 (240 dams).

Process_Step:

Process_Description:

The dams in this file were selected from the National Inventory of Dams (NID). First, a subset of the attributes contained in the NID was selected based on input from the Army Corps of Engineers. Using an ArcView query, the dams with a height of 50 feet or more were selected, along with the dams with a normal storage capacity of 5,000 acre-feet or more, and those 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.) The resulting data set was converted to an ArcView shape file using the "Convert to Shapefile" command.

33 dams that fell outside the 50 States were deleted (1 in Guam, 1 in the Trust Territories, and 31 in Puerto Rico), and 78 dams without coordinates were also deleted. Several misspelled county names were corrected, and the entries in the FIPS_cnty (County FIPS) field were cleaned up. For all dams with a valid county name but no County FIPS, the FIPS code was added based on the listed county name. If two county names were given, the FIPS code used was for the first one listed, or for the county in the listed State. Where the county name was invalid or missing, the county was determined by comparing the dam location to the National Atlas counties file. If the dam fell on a State line, the county name and FIPS code used were those appropriate for the listed State.

The shape file was converted to an Arc/Info coverage and then converted to NAD 83. The result was then converted back to shapefile format.

Entity_Type:

Entity_Type_Label: Dam

Entity_Type_Definition:

Any artificial barrier, including appurtenant works, which impounds or diverts water, and which (1) is twenty-five feet or more in height from the natural bed of the stream of watercourse measured at the downstream toe of the barrier, or from the lowest elevation of the outside limit of the barrier, if it is not across a stream channel or watercourse, to the maximum water storage elevation or (2) has an impounding capacity at maximum water storage elevation of fifty acre-feet or more. This Act does not apply to any such barrier which is not in excess of six feet in height, regardless of storage capacity or which has a storage capacity at maximum water storage elevation not in excess of fifteen acre-feet, regardless of height, unless such barrier, due to its location or other physical characteristic, is likely to pose a significant threat to human life or property in the event of its failure.
