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.

A Spatially Continuous Model of Annual Streamflow Permanence Throughout the Pacific Northwest

An interdisciplinary team comprised of USGS and university scientists has developed the Probability of Streamflow Permanence Model or PROSPER which predicts flow permanence for unregulated and minimally impaired streams in the Pacific Northwest.

Streamflow gains and losses in New Fork and Green Rivers, upstream from Fontenelle Reservoir, Wyoming, October 2015

The Wyoming Landscape Conservation Initiative is a program created to implement a long-term, science-based program of assessing natural resources while facilitating responsible energy and other development and does studies in much of southwestern Wyoming, including all or parts of Lincoln, Sublette, Fremont, Sweetwater, and Carbon Counties. A...

Biogenic coal-to-methane conversion can be enhanced with small additions of algal amendment in field-relevant upflow column reactors

ubsurface coal environments, where biogenic coal-to-methane conversion occurs, are difficult to access, resulting in inherent challenges and expenses for in situexperiments. Previous batch reactor studies provided insights into specific processes, pathways, kinetics, and engineering strategies, but field-relevance is restricted due to limited...

Water-quality, bed-sediment, and biological data (October 2016 through September 2017) and statistical summaries of data for streams in the Clark Fork Basin, Montana

Water, bed sediment, and biota were sampled in selected streams from Butte to near Missoula, Montana, as part of a monitoring program in the Clark Fork Basin of western Montana. The sampling program was led by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the Clark...
