The U.S. Geological Survey's (USGS) mission is to provide reliable scientific information about the Nation's natural resources. An integral part of that mission is to provide consistent, long-term water-resources data. To do so, the Central Midwest WSC operates a widespread surface and ground-water data collection network as well as research on a wide range of scientific issues.
