Welcome To The United States Geological Survey

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 customers, cooperators, and the public. To accomplish our mission, we operate a widespread surface and ground-water data collection network as well as research a wide range of scientific issues throughout Iowa.
