Hydrologic Assessment of the Blackfeet Reservation, Montana

The Blackfeet Nation seeks an increased scientific understanding of the water resources within the Blackfeet Reservation of northwestern Montana. Hydrologic information is needed in order to make informed water management decisions as the Blackfeet Nation moves forward with implementation of the Blackfeet Water Rights Compact as new water-use projects are initiated and as the Blackfeet...

Wyoming-Montana Stream Water-Quality Network - Water Year 2020

The USGS monitors stream water quality in Wyoming and Montana in cooperation with State, County, local, and other Federal agencies. Water-quality data for these sites are available from the USGS National Water Information System Web Mapper application in the form of an interactive map that can be accessed from the Data and Tools tab.

Flaxville Aquifer

The Flaxville aquifer is present in the northern and central parts of the Fort Peck Indian Reservation and consists of sand and gravel that forms extensive plateaus and topographic benches used for dryland farming.  Because many residents rely on groundwater as their primary water supply on the Reservation, the Flaxville and underlying aquifers are important sources of groundwater.  The goal...

EcoFlows: Understanding Streamflow Dynamics in Small Mountain Streams

The WY-MT WSC is collaborating with the Northern Rocky Mountain Science Center to understand the dynamics of streamflows in small, mountain streams during the course of the year, and to describe the amount of variability associated with those measurments. These findings will assist fisheries biologists who are researching temperature and streamflow effects on cutthroat trout and will help...

Characterization and Quantification of Salinity Loads from Blacks Fork above Smiths Fork near Lyman, Wyoming

The Blacks Fork is a stream that contributes a salinity load to the Colorado River Basin. In order to quantify the salinity load, collection of continuous streamflow and specific conductance data, and monthly sampling for total-dissolved solids will occur from April 2018 through September 2019. Calculations of monthly and annual salinity loading from the Blacks Fork will be published in 2020...

Hydrologic Characterization of Potential Sites for Restored and Constructed Wetlands, Montana

Projects conducted by the Montana Department of Transportation (MDT) sometimes result in unavoidable impacts to wetlands and other aquatic habitats. To compensate for these impacts, MDT mitigates the loss of wetlands by providing replacement wetlands within the watershed.

Wyoming Landscape Conservation Initiative: Water Resources

The Wyoming Landscape Conservation Initiative is a long-term science-based effort to assess and enhance aquatic and terrestrial habitats at a landscape scale in southwest Wyoming, while facilitating responsible development through local collaboration and partnerships. The WLCI is an interagency working group of partners that is beginning the process of establishing a much larger coalition of...

WLCI: Long-term streamflow, water-quality, and groundwater data collection

Riparian and aquatic ecosystems in semiarid landscapes like Southwest Wyoming contribute substantially to regional biodiversity. Long-term monitoring data that describe streamflow, surface-water quality, and groundwater levels are needed for assessing possible effects of changes in land use on those ecosystems.

WLCI: Groundwater Streamgages in the upper Green River Basin

Real-time groundwater streamgages are created at existing streamgages by adding streambank wells (piezometers) to expand the understanding of groundwater/surface-water interaction. The object of this project is to:

  • Identify interactions between the stream and near-surface groundwater
  • Evaluate data to determine annual patterns and changes over time
