Measuring flooding in downtown Fargo, ND
USGS hydrologist Dan Thomas prepares to measure record flows on the Red River of the North in downtown Fargo, North Dakota. The orange instrument is an acoustic Doppler current profiler, which is used to measure streamflow as it's pulled across the water.

Measuring high flows in Fargo, ND
An instrument called an acoustic Doppler current profiler (ADCP) takes streamflow measurements during flooding. The ADCP is attached to a buoy that is dragged in the water either alongside a boat or by hand. USGS hydrologist Dan Thomas points to the ADCP sensor on the Red River of the North during flooding in downtown Fargo, ND.
