Office Information and Locations

The Wyoming-Montana Water Science Center (WSC) is one of over 40 Water Science Centers in the U.S. Geological Survey (USGS). The Water Science Center's mission is to collect, analyze and disseminate in an impartial manner the hydrologic data and information needed to wisely manage water resources for the people of the United States and the States of Wyoming and Montana.

The Water Science Center main offices are located in Helena and Cheyenne. Other offices include one Montana field office in Billings and two Wyoming field offices in Casper and Riverton. Addresses and phone numbers are provided below.

What We Do

  • We operate local and statewide networks to collect high-quality data that define natural and human-induced hydrologic conditions.
  • We analyze hydrologic processes through investigations and research to increase understanding of important water-resource issues and to promote informed decision making.
  • We maintain real-time and historical data bases and publish peer-reviewed interpretive and data reports to disseminate unbiased hydrologic information.

We form partnerships with Federal, State, and local agencies, and other public organizations to ensure that our work is relevant and useful.

Funding for the Wyoming-Montana Water Science Center comes from a variety of sources, including direct Federal appropriations, other Federal agencies, and a cooperative program that allows the Water Science Center to partially match funding with state and local agencies. Information concerning USGS products and services can be obtained from:

Data Collection

Basic hydrologic data collection, processing, analysis, dissemination, and archiving are major parts of the Wyoming-Montana Water Science Center program. Streamflow data, for example, are used for flood and water-supply forecasts, planning and design, river regulation, streamflow statistics, and research investigations. Much of the data are available on a near-real-time basis by satellite telemetry. Types of data currently collected include:

  • Streamflow data for 300+ gaging stations
  • Continuous groundwater level data at approximately 50 wells
  • Water-quality data for about 150 sites
  • Stream-sediment transport data
  • Climate data

Database Capabilities

USGS data are stored and maintained in long-term, quality-assured data bases. The data bases contain data for Wyoming, Montana, and the rest of the nation and are accessible to the public. The data include:

  • Streamflow, reservoir, and lake data
  • groundwater data
  • Continuous and discrete water-quality data
  • Water-use data
  • Geographic Information System (GIS) data


The chief purpose of hydrologic projects is to help cooperating agencies solve water problems. For example, investigative results have been used to manage storm-water runoff, to develop groundwater management plans, and to identify areas of water-quality degradation. These investigations address many water issues:

  • Water-quantity and -quality assessments
  • Toxic substances in natural waters and biota
  • Rural and urban nonpoint pollution
  • Surface-water / groundwater interactions
  • Sediment transport and chemistry
  • Effects of climate change
  • Wetland functions and hydrology
  • Aquifer and streamflow characterizations
  • Frequency and magnitude of droughts and floods

Analytical Techniques

The Wyoming-Montana Water Science Center uses state-of-the-art as well as traditional methods that include quality assurance and quality control:

  • Watershed modeling
  • Flood and low-flow frequency analysis
  • Sediment and chemical load determination
  • Aquifer testing
  • Aquatic biological assessments
  • Aquatic community analysis
  • Geographic Information Systems (GIS)
  • Acoustic doppler velocity measurements
  • Groundwater age dating
  • Surface and borehole geophysics
  • Evapotranspiration analysis
  • Groundwater recharge modeling
  • Solute-transport modeling
  • Geochemical modeling
  • Groundwater flow modeling
  • Water, sediment, and tissue analysis

Water-quality samples are collected and analyzed for a wide range of constituents, including major inorganics, nutrients, trace elements, dissolved gases, pesticides, isotopes, organic solvents, petrochemicals, and biological indicators.
