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.

Simulation of Groundwater Flow in the Madison and Minnelusa Aquifers, Black Hills Area

The Madison and Minnelusa aquifers are critically important water resources that were a primary focus of the Black Hills Hydrology Study of the 1990s. These aquifers have a large influence on surface-water systems and provide the most important source of groundwater for municipal, domestic, agricultural, and industrial use in the area. Rapidly increasing demand from these aquifers may affect...

Using Quantile Regression to Investigate Ecological Limiting Factors

Unexplained heterogeneity in statistical models of animal responses to their physical environment is reasonable to expect because the measured habitat resources are a constraint on—but not the sole determinant of—abundance, survival, fecundity, or fitness. The ecological understanding and reliability of management predictions based on animal habitat models can be improved by shifting focus ...

Restoring Montana Pothole Wetlands - Demonstration Sites and Adaptive Management

Geologic processes from the last ice age have generated extensive areas of pothole wetlands in several Montana landscapes. The Laurentide ice sheet, originating in the Northwest Territories, provided the dominant force in eastern Montana. Similar landscapes developed in the broad valleys of western Montana through the actions of the Cordilleran ice sheet, originating in the mountains of...

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
