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.

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. Sampling was initiated in response to elevated trace-element concentrations and the designation of areas in the upper Clark Fork basin by the U.S. Environmental Protection Agency (USEPA) as National Priorities List...

Establishment of a baseline groundwater monitoring program in an area identified for energy development on the Blackfeet Reservation, Montana

As a result of energy development, the Blackfeet Environmental Office has developed a groundwater monitoring program specifically focused on the Cut Bank Creek watershed of the Blackfeet Indian Reservation. The addition of groundwater data to an existing surface-water monitoring program will help the Blackfeet Tribe develop a more complete understanding of the current conditions of their water...

Delineation of Brine Contamination in and near the East Poplar Oil Field, Fort Peck Indian Reservation, Northeastern Montana

Brine is a byproduct of crude oil production. Handling and disposal of brine during the last 50 years in the East Poplar oil field has resulted in contamination of not only the shallow Quaternary aquifers, but also the Poplar River. Previous investigations have documented and partially delineated the extent of brine contamination in the East Poplar oil field during the early 1990s...

Williston and Powder River Basins Groundwater Availability Study

The development of two nationally important energy-producing areas, the Williston structural basin (containing the Bakken Formation) and Powder River structural basin, provide a critical opportunity to study the water-energy nexus within a groundwater context. Large volumes of water are needed for energy development in these basins. The hydraulically connected aquifers in the...

Living on the Edge: Predicting Effects of Climate Change on Native Fishes in Northern Great Plains Streams

Organisms that live in the semi-arid prairies in the Northern Great Plains are able to live through conditions of extreme heat, cold, floods, and drought. The fish that inhabit the warm, turbid waters of northern Great Plains streams are indicators of change in these delicate ecosystems, where water quantity and water quality are often precariously close to ecological tolerance limits. In fact...

Assessment of Aquatic Communities in Northeastern Wyoming and Southeastern Montana

The Powder River Structural Basin (PRB) in northeastern Wyoming and southeastern Montana is an important source of energy resources for the United States. Resources developed from the basin include coal, oil, uranium, conventional natural gas, and within the last decade coal-bed natural gas (CBNG) which often is referred to as coal-bed methane. As of 2008, about 20,000 CBNG wells had been...

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...
