Description: Dam-Lines in the United States This dataset is provided as a polyline shapefile. According to the HSIP Tiger Team Report, a dam is defined as a "water barrier or an embankment built across the course of a stream or into a body of water to control and/or to impound the flow of water (breakwater, dike, jetty)." This dataset is based on the U.S. Army Corps of Engineers (USACE) National Inventory of Dams (NID) and the United States Geological Survey (USGS) National Hydrography Dataset (NHD). Records in the NID attributed as "Dams" were extracted by TGS under the classification of a maximum capacity of at least 2800 acre feet and/or classified as a "High Hazard" by using the query (([max_stor]>=2800) or ([hazard]="H")). Dam locations were digitized using any combination of ortho imagery, topographic DRGs, NAVTEQ streets, NHD flowlines, NHD landmarklines, TIGER hydrography, contact with authoritative sources or web research. A line was created by tracing the crest of the dam using referencing imagery and the NHD flowlines. Entities classified as both MaxCapacity and High Hazard are represented once. All information for entities located on the grounds of a military base should be treated as "For Official Use Only". These entities are indicated by "-DOD" appended to the end of the entity's name in the [NAME] attribute and by "UNCLASSIFIED - TREAT AS FOUO" in the [SECCLASS] attribute. Text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. All diacritics (e.g., the German umlaut or the Spanish tilde) have been replaced with their closest equivalent English character to facilitate use with database systems that may not support diacritics. No entities for American Samoa, District of Columbia, the Northern Mariana Islands or the Virgin Islands are included in this dataset. The currentness of this dataset is indicated by the [GEODATE] attribute. Based upon this attribute the oldest record dates from 01/18/2007 and the newest record dates from 02/06/2009.
