In the aftermath of the 2018 Carr Fire, northern California, sediment has eroded from burned hillslopes and accumulated in some areas of Whiskeytown Lake. A recent sediment deposit is shown here in the Whiskey Creek section of the lake.

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.
