In September 2020 USGS tested ground-penetrating radar (GPR) mounted on a cableway over the Gunnison River in Colorado. USGS has been testing use of the GPR to map river bathymetry (profiles of water depth along the river), measurements often made by personnel in the water or on boats.

Watch Hurricane Sally move through the southeast U.S. in this data visualization, and see USGS streamgage measurements spike as the storm’s extreme rainfall leads to intense flooding. USGS streamgages provide critical information during storms to flood forecasters and emergency managers as they make decisions that contributes to protecting lives and property.
