Did you know that there are sometimes volunteer opportunities for hydrogeology students to work with USGS?

The USGS is advancing the use of large-scale particle-image velocimetry (LSPIV) - a method that uses innovative video analyzation techniques - to measure streamflow.

USGS scientists installed a thermal imaging camera on a current USGS streamgage on the Neversink River near Claryville, New York. This equipment will help monitor surface water temperatures and can help understand the amount of groundwater contributing to surface runoff.

Each summer, interns join USGS offices around the Nation in support of our water studies.

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.
