Groundwater-Level Measurement near Jewel Cave National Monument, SD

USGS groundwater hydrologist, Bill Eldridge, is lowering a transducer into an observation well near Jewel Cave National Monument to monitor water-level changes in the Madison aquifer. The data collected will be used to update previously published groundwater-altitude maps to help better understand groundwater flow. The work is being conducted in cooperation with the

Little White River near White River, SD

This photograph was taken at Little White River near White River, SD (USGS streamgage 06450500) when the streamflow was 138 cubic feet per second. During the winter, ice conditions create challenges for field staff in the collection of streamflow measurements.  Safety is of highest importance.  If the stream is fully iced over, then holes are drilled across the stream and

Streamflow Measurement Under Ice at Cheyenne River near Wasta, SD

 During wintry conditions, streamflow is often measured under ice. This often means using an ice auger to cut holes through the ice, at increments across the full width of the stream. This photograph shows a USGS Hydrologic Technician making a streamflow measurement on January 4, 2018, at the Cheyenne River near Wasta, SD (streamgage 06423500;

Streamflow Measurements Under Ice Using Acoustic Doppler Technology

Hydrologic Technicians from USGS offices across North and South Dakota took part in training on how to make flow measurements under ice using acoustic Doppler technology. This technology increases measurement quality, while decreasing time, effort, and risk to the individuals making the measurements. The photograph was taken at USGS streamgage 05059300 Sheyenne River above
