Description: U.S. Army Corps of Engineers National Inventory of Dams (NID). A dam is included in the National Inventory of Dams if: (1) it is a High or Significant hazard potential class dam or, (2) it is a Low Hazard potential class dam that exceeds 25 feet in height AND 15 acre-feet storage or, 3) it is a Low Hazard potential class dam that exceeds 50 acre-feet storage AND 6 feet height. For definitions of hazard, height and storage, please see the data dictionary. In 1986 Congress enacted the Water Resources Development Act (P.L 99-662). This legislation authorized the U.S. Army Corps of Engineers (USACE) to maintain and periodically update the National Inventory of Dams, and appropriated funds for that purpose. This GIS coverage was created by extracting dams from the 75,187 dams cataloged in the U.S. Army Corps of Engineers National Inventory of Dams. NID coverage currentness is October 2000.The coordinate system is UTM Zone 17 (NAD 83). It was downloaded from the West Virginia GIS Technical Center Data Clearing House in July 2011 by the WVDOH GTI Section.
