Group: Summary
  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 National Atlas of the United States in
  the use of these data.
  
  This map layer portrays major dams of the United States, including Puerto
  Rico and the U.S. Virgin Islands.  The map layer 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 79,777 dams in the U.S. Army Corps of Engineers National
  Inventory of Dams.  This is a replacement for the April 1994 map layer.
  
  In the online National Atlas of the United States Map Maker, 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 (1280 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 (290 dams).
