Measuring high water flow on the Maple River, ND

Detailed Description

This is not a lake! A USGS crew measures high flow during flooding on the Maple River near Mapleton, North Dakota. The instrument being pulled across the water is an acoustic Doppler current profiler (ADCP), which is used to measure streamflow. USGS sreamgaging equipment is visible in the foreground, and the streamgage station is located just beyond and to the right of the hydrologist tugging the ADCP.
