![Marshmallow-like Formations on Cannonball River at Regent, ND](https://d9-wret.s3.us-west-2.amazonaws.com/assets/palladium/production/s3fs-public/styles/masonry/public/thumbnails/image/20180403_154142.jpg?itok=PI5KE9lZ)
Marshmallow-like formations were photographed on the Cannonball River at Regent, North Dakota (USGS streamgage 06350000) on April 3, 2018. Foam is produced naturally from organic material in the water in combination with turbulence resulting from water flowing over the weir.

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.

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.

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.

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.
