  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_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.
