Description:
Abstract: This map layer includes the locations of over 500 majors dams in New York State. 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. This data set portrays major dams of New York State. 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: 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 U.S. Geological Survey in the use of these data.
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 (1173 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 for display purposes. The result was then converted back to shapefile format.

Process_Step:
Process_Description: The dams in Puerto Rico and the U.S. Virgin Islands that met the criteria for large dams were selected from the NID. There were 31 dams in Puerto Rico and none in the U.S. Virgin Islands. The same attributes were selected as were used for NatlasDams. Both the Fips_state and Fips_cnty fields were blank for these dams, so the State FIPS code was entered, and the county FIPS code was entered where appropriate. One invalid county name was corrected by comparing the dam location to the National Atlas counties file. The resulting shapefile was converted to an Arc/INFO coverage, converted to NAD83 for display purposes, and merged with the NatlasDams data. The resulting file was then converted back to shapefile format.

Process_Description: In order to geoprocess spatial files for New York State from the National Atlas Data for distribution in CUGIR, the nationwide data files were added to a map document in ArcInfo 8.2. Using the geoprocessing wizard's clip function, the spatial files were clipped to the detailed New York polygon.

Entity_and_Attribute_Information

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 or 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.
