The U.S. Geological Survey, in collaboration with the Department of Energy, University of Montana, Northern Arapaho Tribe, and Liverpool John Moores University, is studying the interaction of a contaminated groundwater plume enriched in uranium and other trace elements with water, sediment, and biota along a 3 km reach of the Little Wind River in central Wyoming. The source of the contaminants is from a reclaimed uranium mill site near Riverton, Wyoming. This Data Release makes available data collected from June to September, 2016 and August to September, 2017. Data collected during these time periods include: (1) radon, major-ion, and trace-element concentrations in surface-water, groundwater, and pore-water samples;...

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) recently completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages operated by the WY–MT WSC. In association with the report, this data release presents peak-flow frequency analyses for 14 selected streamgages in the Beaverhead River and Clark Fork Basins that were based on methods described by Sando and McCarthy (2018). The results are presented in three child items: a child...

This U.S. Geological Survey (USGS) Data Release provides data to estimate water use associated with continuous oil and gas development in the Williston Basin during 1980-2017. Data included: Data records from the national hydraulic fracturing chemical registry, FracFocus, including the state, county, latitude and longitude of each well, and the year and volume of water used for hydraulic fracturing for the years 2010-2017 in Montana and North Dakota. IHS Markit (TM) data reported in 2018 including the number of wells used for hydraulic fracturing treatments; the volume of oil, gas and water produced; well counts for produced oil, gas, and water. Montana Department of Natural Resources and Conservation (MTDNRC)...

In association with the report, this data release presents peak-flow frequency analyses for 99 selected streamgages that serve as examples showing various aspects of the WY-MT WSC frequency-analysis methods. The results are presented in three child items: a child item containing the results excel spreadsheet,...
