USGS Responds to Spring Flooding
U.S. Geological Survey field crews are measuring flooding across the country as spring weather is in full swing. Warming temperatures, increased precipitation and snowmelt have caused moderate to major flooding in the upper Midwest, East Coast, Central Plains and the Southeast portions of the country.
Salinity Cycles in Lower Colorado River Caused by Precipitation Patterns in Upper Basin
A new study shows that mysterious cycles in salinity in the lower Colorado River are a result of precipitation patterns in the headwaters of the upper basin more than a thousand river miles away. The salinity levels generally repeat about every 10 years.
Mercury Concentrations in Lake Powell Higher in Side Canyons
Mercury concentrations within Lake Powell are highest in side canyons within the lower portion of the reservoir, according to a new U.S. Geological Survey report. This finding is part of a study to better understand why mercury concentrations in striped bass are higher in the lower part of the reservoir.

Discharge and dissolved-solids characteristics and trends of Snake River above Jackson Lake at Flagg Ranch, Wyoming, 1986–2018
The headwaters of the Snake River are in the mountains of northwestern Wyoming. Maintaining the recognized high quality of water in Grand Teton National Park is a National Park Service (NPS) priority. To characterize and understand the water resources of Grand Teton National Park, the NPS established a monitoring program to monitor the quality of...

Water-quality, bed-sediment, and invertebrate tissue trace-element concentrations for tributaries in the Clark Fork Basin, Montana, October 2017–September 2018
Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a monitoring program in the Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Clark Fork Basin...

Quantification of trace element loading in the upper Tenmile Creek drainage basin near Rimini, Montana, September 2011
The principle sources of trace elements entering upper Tenmile Creek, Montana, during September 2011, four trace metals and the metalloid arsenic, were identified and quantified by combining and analyzing streamflow data determined from tracer injection with trace-element concentrations and related water-quality data determined from synoptic...
