Unified Interior Regions
Montana
Welcome to the Midwest Region! Our region includes 18 Science Centers in 11 States from the Great Lakes to the Dakotas, south to Missouri and Kentucky. Our streamgage network is used to monitor and assess water resources across the region. Other research focuses on fisheries and aquatic ecosystems, midcontinental plant/animal species, invasive species, wildlife disease, and energy and mining.
Northern Rocky Mountain Science Center (NOROCK)
Scientists from the Center work in the northern Rocky Mountains and across the U.S. Many work throughout the world on issues as diverse as global climate change, aquatic ecology, wildlife diseases, bison ecology, and large carnivores.

Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin
The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...
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...

Critical Commodity Studies, Stillwater Complex, Montana
Scientific research can make our resource assessments of critical minerals more effective. This project focuses on the Stillwater Complex, Montana, which has rocks enriched in platinum-group elements (PGE), chromium, cobalt, and nickel. Project objectives are to update databases, evaluate new mapping techniques, document new styles of mineralization, and document and support research on the...
Glaciers and Climate Project
Scientists with the Glaciers and Climate Project study many of the pertinent impacts that glaciers present to society, such as altering hydrologic cycles, contributing to sea-level rise, and creating environmental hazards.
Grinnell Ridge, Gem & Salamander Glaciers 1910 - 2017
In 1910, Morton Elrod documented how Grinnell Glacier’s mass filled the basin and how the glacier was then joined with the ice apron we now call the Salamander (right). Close inspection of Gem Glacier (top-center) reveals a loss of thickness / volume over the past 107 years as well.

StreamStats in Montana and Wyoming
StreamStats is a Web-based geographic information system application that provides users with access to basin and streamflow characteristics for gaged and ungaged streams.
Land Treatment Exploration Tool
The Land Treatment ExplorationTool provides a practical resource for managers who are planning restoration and rehabilitation actions on public lands. The tool generates a variety of spatial products while being user friendly for all levels of GIS expertise, even to those with little or no experience.
Clark Fork Water-Quality Monitoring
The U.S. Geological Survey (USGS) has collected water-quality samples from selected stream sites upstream from Missoula since 1985.
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.

Electron microprobe data for monazite and xenotime used in consideration of gold deposit formation models
The genetic origin of many gold deposits, including Pogo in Alaska, remains controversial with questions as to whether they formed due to magmatic-hydrothermal or metamorphic-hydrothermal fluids. Gaining a better understanding of the formation mechanisms for these deposits is critical for defining proper exploration criteria in gold-bearing regions and production within these deposits. Monaz...
Reanalysis of Selected Archived NURE-HSSR Sediment and Soil Samples from Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah
Beginning in November of 2015, the U.S. Geological Survey (USGS) undertook a project to reanalyze approximately 60,000 archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A s
Streamflow Observation Points in the Pacific Northwest, 1977-2016
This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.
