(United States) Geological Survey (USGS) An agency of the U.S. Department of Interior responsible for providing extensive earth-science studies of the Nation’s land, water, and mineral resources. The USGS was established by an act of Congress on March 3, 1879, to provide a permanent federal agency to conduct the systematic and scientific “classification of the public lands, and examination of the geological structure, mineral resources, and products of national domain.” An integral part of that original mission is to publish and distribute the earth-science information needed to understand, plan the use of, and manage the nation’s energy, land, mineral, and water resources. Since 1879, the research and fact-finding role of the USGS has grown and been modified to meet the changing needs of the nation it serves. As part of that evolution, the USGS has become the map-making agency for the federal government, the primary source of data on surface- and ground-water resources of the nation, and the employer of the largest number of professional earth scientists. The USGS is organized into three operational Divisions: the National Mapping Division (NMD), charged with development and application of mapping and Geographic Information System (GIS) technology, the Geologic Division (GD), which conducts geologic mapping and research, and the Water Resources Division (WRD). The mission of the Water Resources Division of the USGS is to provide the hydrologic information and understanding needed to manage the nation’s water resources to benefit its residents. Typical water resource programs sponsored by the WRD include:
