This DataVisualization shows the severity of flooding in the Midwest . As of June 1, 2019, 17 USGS streamgage sites in red had the highest streamflow for the entire period of record available. Both the Mississippi and the Arkansas rivers are seeing record breaking flows.

USGS hydrographers collect tens of thousands of streamflow measurements every year. In-water work by personnel is one of the most dangerous aspects of USGS hydrologic studies, especially during high-flow conditions. In May 2019, USGS continued testing of a light-weight, self-contained ground-penetrating radar (GPR) system that can be mounted on a small drone.

The USGS, in cooperative research and development with GuidelineGEO, tested an 80 GHz self contained ground penetrating radar unit on a DJI Matrice 600 hexcopter (left). This platform was tested for flight performance and for measurement of river channel cross-sectional area as well as river water depth and river width.

The sensor mounted on the drone is called the Qcam and is a Doppler radar sensor providing velocity from a hovering position above the river. USGS hydrologic technician (left) aboard a USGS John Boat mounted with Acoustic Doppler Current Profiler observes the Qcam conducting a measurement.
