Water Resources of Wyoming and Montana
Welcome to the USGS Wyoming-Montana Water Science Center. These pages are your source for water-resource information collected and interpreted by the U.S. Geological Survey in Wyoming and Montana. Here you'll find information on Wyoming's and Montana's rivers and streams. You'll also find information about ground water, water quality, and many other topics. The USGS operates the most extensive satellite network of stream-gaging stations in the state, many of which form the backbone of flood-warning systems.

New Interactive Tool: StreamStats
A limited version of StreamStats, a web-based GIS application for Montana’s streams, has been recently deployed and allows users to:
- delineate basins (zooming to at least 1:20,000 to access the basin delineation tool ()
- compute basic physical characteristics for delineated basins
- compute climatic characteristics for delineated basins
The fully implemented StreamStats application for Montana will be completed in early 2016, and will allow users the additional functionality to:
- retrieve previously computed streamflow characteristics for selected streamgages
- estimate streamflow characteristics for stream reaches without a streamgage
Hydrogeology of the lower Tertiary aquifer system is described along with a new map showing elevations and flow paths of groundwater. Included are data describing changes in groundwater levels in selected wells over the last 50 years.
Climatic, geological, and environmental data were coupled with observational stream intermittency data to predict alpine headwater stream intermittency. The study determined that the most important variables to predict the probability that a stream would maintain year-round streamflow were snowpack persistence, temperature (mean annual, mean monthly, and minimum), and surficial geology.
Investigation of microbial proteins provides insights on how microorganisms evolved an efficient pathway to generate methane.
