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.

Ice Jam on White River near White River, SD (06447450)

Ice jam on the White River near White River, SD (USGS streamgage 06447450) on March 15, 2018. Ice jams occur when floating ice carried with a stream’s current accumulate at any obstruction to the stream flow. These ice jams can develop near river bends, mouths of tributaries, areas of decreased river slope, and upstream of obstructions like bridges. Ice jams can cause
