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.

In September 2020, field crews in the USGS Nevada Water Science Center measured spring flow and collected water-quality samples at locations around the Soldier Meadows Spring Complex in Nevada. The spring complex is the only home of a small fish called the desert dace.

In this NOAA satellite image from Sept. 15, 2020, Hurricane Sally approaches the U.S. Gulf Coast, Hurricane Paulettte creates storm waves far out in the Atlantic, and Tropical Storms Teddy and Vicky lie near the coast of Africa. Two tropical depressions are also developing; one of them is not visible in this image.

The left axis is a visualization of an ensemble of solutions (crosses and dashed lines) iteratively moving down gradient on an objective function surface (color flood) in 2-D parameters space, with the associated prior (gray) and posterior (blue) parameter marginal distributions shown on the two right stacked axes.

This USGS streamgage on Schantz Spring near Wescosville, Pennsylvania was partially submerged after floodwaters from Tropical Storm Isaias quickly rose and flooded the area.

Fisseha Mengistu, USGS hydrologic technician, uses a device that lowers a water sampler into the creek below to collect samples used for water quality testing. Experts will be able to use this data to track how Tropical Storm Isaias impacted water quality in the area. This work was done on Rock Creek in Washington, D.C.
