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 Sheyenne River Diversion near Horace, North Dakota (https://waterdata.usgs.gov/nd/nwis/dv?referred_module=sw&site_no=05059300).
