Visualization of an ensemble of solutions for PEST++

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.

Flooded Pennsylvania Streamgage after Hurricane Isaias

This USGS streamgage on Schantz Spring near Wescosville, Pennsylvania was partially submerged after floodwaters from Tropical Storm Isaias quickly rose and flooded the area. USGS crews arrived on scene August 4 to

Measuring streamflow on Rock Creek after Hurricane Isaias

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. Real-time data for this water quality site is

USGS intern prepares geophysical equipment

In this photo, USGS intern Brett Trottier (right) is learning how to prepare and deploy geophysical equipment from USGS hydrologist Eric White (left). The towed transient electromagnetic (tTEM) system is used to map the shallow subsurface to help us understand geologic and hydrogeologic conditions. In addition to the usual field safety procedures, Trottier and White are

U.S. River Conditions, April to June 2020

This is an animation showing the changing conditions of USGS streamgages from April 1, 2020 to June 30, 2020. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding. While we do see floods in this animation, we also see a number of low

Sugar Creek, near New Palestine, Indiana

Sugar Creek, near New Palestine, Indiana. Sugar Creek is part of a long-term USGS stream monitoring project, and was one of 72 U.S. streams and rivers investigated for pesticide occurrence. On average, 26 pesticides were detected in samples collected from Sugar Creek during 2013–17; 16 of the 122 samples collected at this site had a Pesticide Toxicity Index score that

USGS crews install a rapid deployment gage, Midland, MI

A USGS hydrologic technician finishes installation of a rapid-deployment streamgage at Gordonville Road on the Tittabawassee River in Midland, Michigan. A USGS crew in the distance makes streamflow measurements using a boat-mounted acoustic Doppler current profiler. The USGS responded to major flooding at some locations in lower
