Unified Interior Regions
South Dakota
Surface water and groundwater provide important water supplies in South Dakota. Major rivers include the Big Sioux, James, Cheyenne, and Missouri Rivers. Key aquifers include the Dakota, Madison, Minnelusa, and Big Sioux aquifers. The Dakota Water Science Center has many studies that focus on these resources as well various other national and international studies.

Most species of migratory birds in the Northern Hemisphere make two long trips each year, one north for nesting and the other south for the winter. New information collected by USGS scientists shows that individuals of at least one species, the prairie falcon, make three separate long trips each year.
In its latest report on water use in the United States, the USGS looked at the nation's dependence on ground water. The report entitled Estimated Withdrawals from Principal Aquifers in the United States, 2000, provides details of ground-water withdrawals and use from principal aquifers in each state.
The U.S. Geological Survey (USGS) presented the 2004 John Wesley Powell Award to governmental, educational and organizational partners who have worked with the USGS to strengthen The National Map, to teach the importance of remote sensing data, to communicate USGS science, and to provide information to water managers about floods.
A new report by the U.S. Geological Survey (USGS) describes changes that have taken place in the High Plains aquifer from the time that significant ground-water pumping began in the 1940’s to the year 2000.
A new report by the U.S. Geological Survey (USGS) describes changes that have taken place in the High Plains aquifer from the time that significant ground-water pumping began in the 1940’s to the year 2000. The results show a six percent decrease in the volume of water stored in the High Plains (or Ogallala) aquifer.
