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 (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.

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.

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.

This 2014 photo shows the new location of the USGS streamgage that measures high flows on the Trinity River in Dallas. The gage was once located on a pier, but in 1975 was moved next to the stream.

In the earlier years of streamgaging, large “stilling wells” were constructed to contain the equipment needed to collect streamflow data. Historically, most of the streamflow equipment may have been located in these large structures, which were placed in the middle or next to the stream.
