USGS intern deploys fiber-optic cable for groundwater/surface-water study
In this photo, a USGS intern is deploying fiber-optic cable along the bed of a trout stream to measure temperature in June 2016. This fiber-optic distributed temperature sensing system is used by USGS scientists to identify areas where groundwater is discharging into the stream.

Public-supply well tapping the High Plains aquifer, Texas
This public-supply well taps groundwater in the High Plains aquifer in Texas. The strontium concentration in the sample from this well was 4,630 micrograms per liter, exceeding the health-based screening level of 4,000 micrograms per liter.

USGS ecologist Jaimie Gillespie measuring a Sediment Elevation Table
USGS ecologist Jaimie Gillespie measuring a Sediment Elevation Table (SET) on the Pamunkey River, VA. This SET is part of a larger project which consists of two SETs at each of five research sites, on both the Mattaponi and Pamunkey Rivers spanning Oligahaline to non-tidal conditions.

Colorado River Near Moab, Utah.
Water flowing on the Colorado River near Moab, Utah.
The entire Colorado River Basin currently supports 50 million people, and that amount is expected to increase by 23 million between 2000 and 2030. A new USGS study shows more than half of the streamflow in the Upper Colorado River Basin originates as groundwater.

USGS Streamgage near Derby, Texas
Currently, most of the streamflow equipment is located on a streambank or bridge. Large structures are no longer needed at most streamgage locations. Today, streamgage equipment can be contained in small metal shelters that are located on streambanks or bridges.
