Data

The USGS Wyoming-Montana Water Science Center (WYMT 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...

This dataset includes the field measurements and laboratory analyses of surface water, seston, fish tissue, and sediment samples collected from Bighorn Lake, within Bighorn Canyon National Recreation area (BICA), during high flow (July 2015) and low flow (August 2016) conditions. The study area includes 7-9 sampling sites that follow a transect spanning the entire length of the reservoir...

The purpose of the crest-stage gage network is to inventory and monitor peak discharges throughout the state of Montana, with special emphasis on streams that may damage transportation infrastructure. Recorded data documenting peak streamflow at various sites within the state will be used by the Montana Department of Transportation to support assessments of culvert size, bridge...

Streams throughout the country are routinely sampled for their water quality. Water-quality data are available for active sites and historical sites from the USGS National Water Information System Web Interface (NWISWeb). NWISWeb has discrete water-quality sample data as well as continuous water-quality data.

Wyoming-Montana Stream Water-Quality Network

Mining in the upper Clark Fork Basin has resulted in substantial effects on water quality from large amounts of waste materials enriched with metallic contaminants. The U.S. Geological Survey has collected data since 1985 to document changes in water quality that might have resulted from remediation activities.

Four wells in the WLCI area are continuously monitored to help describe the interaction between the groundwater and surface water.

The National Water Information System (NWIS) is the USGS water data portal where you can find a wealth of historic and real-time data related to floods. The NWIS website also is where you can query peak streamflow data by station, state ( Wyoming or Montana), or region.

The USGS FloodWatch website is a map-based resource from USGS WaterWatch that gives users hourly visual updates for flood conditions at over 3000 locations across the United States ( Wyoming or Montana). Learn how to use FloodWatch.

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Wyoming. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Data from wells in Wyoming; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
