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.

Landsat in Action - Changing Forest Phenology with Andrew Elmore

When parking lots go up, when rooftops multiply, land cover and land uses change. Professor Andrew Elmore with the University of Maryland’s Center for Environmental Science understands that very well, and explains how he uses Landsat to study and quantify that change in USGS EROS’ latest “Landsat in Action” video conversation. Elmore delves into the changing phenology of
