The Willwood Working Group Two of Wyoming conducted an experimental sediment release from Willwood Dam from April 11-13, 2023. The experiment involved opening sluice gates at the base of Willwood Dam to draw down the dam pool which created energy to mobilize sediment deposits behind the dam. The U.S. Bureau of Reclamation released up to 4,000 cubic feet per second from Buffalo Bill Dam...

In 2023, the U.S. Geological Survey, in cooperation with Riverside Energy Michigan, LLC, conducted an injection experiment to monitor the natural rate of biogenic methane generation in the Mortensen A4-24 well which was completed in the Antrim Shale and located in Antrim County, Michigan, United States of America. Approximately 20 barrels (bbl) of produced water was pumped from the well...

With the Surface-Water Index of Permanence (SWIPe) we provide a standardized metric for describing one- to five-year anomalies of the annual minimum surface-water extent of streams and wetlands for multiple spatial scales including basin (4-digit hydrologic unit codes [HUCs]) to subwatersheds (12-digit HUCs). Drier conditions are represented by negative SWIPE values that range from 0 to...

The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office, developed streamflow statistics for active (through September 30, 2021) and discontinued USGS streamgages in and near Wyoming with 10 or more years of daily mean streamflow record. Streamflow at each streamgage was assessed for degree of human alteration owing to dams and diversions before...

This data release includes SnowModel output for three headwater study areas in Colorado at seven spatial resolutions and from two forcing datasets over a 40-year period from water year 1980 to 2019. The resolutions include 30 m, 50 m, 100 m, 150 m, 250 m, 500 m, and 1,000 m. The model was run with a 3-hour temporal resolution from September 1, 1980 to August 31, 2019. Two meteorology...

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Sando and McCarthy, 2018) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines (England and others, 2019). The methods are used to provide estimates of peak-flow quantiles for 66.7-, 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance

This data release contains output from a numerical snow simulation for a 65 kilometer (km) × 81 km model domain in parts of Montana and Wyoming, United States, encompassing the Gallatin River watershed upstream of the U.S. Geological Survey streamgage near Gallatin Gateway, MT (06043500). Weather Research and Forecasting (WRF) Model convection-permitting and orography-resolving regional...

A study to assess the potential for long-range transport of selenium from the Elk River valley (British Columbia, Canada) was completed by the U.S. Geological Survey (USGS) using an analysis of total selenium concentrations and loads at six sites in the Elk, Kootenay, and Columbia Rivers in British Columbia, Canada. This dataset contains discrete total selenium concentration data and...

This data release includes laboratory analyses for fish tissue samples collected from Lake Koocanusa and the Kootenai River Basin in Montana during 2022. Samples were collected by the U.S. Geological Survey (USGS) Wyoming-Montana Water Science Center (WY-MT WSC) in cooperation with Montana Fish, Wildlife and Parks (MT FWP) and Montana Department of Environmental Quality (MT DEQ)...

In 2019, the U.S. Geological Survey (USGS), in cooperation with the Blackfeet Water Department, initiated a multi-year hydrologic investigation of the Blackfeet Indian Reservation. The investigation was designed to increase understanding of the water resources of the Blackfeet Indian Reservation including Birch Creek which forms the southern boundary of the reservation. Streamflow is...

This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish with a route...

A before-and-after study design was used to examine effects of changes in cattle grazing practices on channel stability in Muddy Creek, an arroyo in the Colorado River headwaters. The changes in grazing practices were abrupt and focused on keeping cattle out of the riparian zone and increasing herd movement. We digitized 620 meander loop cutoff geometries within the digitized alluvial...
