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.

Smith River Watershed Investigations
The Smith River watershed is an important recreational and agricultural area in Meagher and Cascade counties in west-central Montana. Thousands of visitors travel to the area annually to float and fish the Smith River. Additionally, most of the water used to irrigate 36,000 acres of the upper Smith River watershed is withdrawn from the Smith River or its tributaries. During a...
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...
Yellowstone River Basin Water-Quality Assessment
The Yellowstone River Basin (YELL) study-unit in Wyoming, Montana and North Dakota, is part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound, scientific...
Tongue River Surface-Water-Quality Monitoring Network
Coal-bed methane development is in the initial stages of exploration and production in the Tongue River watershed. Long-term monitoring is needed to provide information to evaluate any changes or trends in surface-water quality and support informed decisions about resource use and management. The goals of this monitoring program are to collect water-quality data and disseminate...
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...
Diel cycling of trace metals in streams
Historically, scientists have assumed that a properly collected water sample will provide an accurate assessment of constituent concentrations in a water body on a given day assuming constant hydrologic conditions. However, an increasing body of evidence indicates that the concentration of many potentially toxic trace elements (such as arsenic, cadmium, copper, manganese, zinc) in streams can...
Drought Conditions in Wyoming and Montana
The USGS monitors drought conditions at more than 300 streamgages across Wyoming and Montana. Low-flow conditions are expressed as percentiles comparing current (within the past few hours) instantaneous flow to historical daily mean flow for all days of the year.
Streamflow Statistics for Unregulated and Regulated Conditions for Selected Locations on the Yellowstone, Tongue, Powder, and Bighorn Rivers, Montana
Major floods in 1996-1997 on the Yellowstone River intensified public debate over the effects of human activities on the Yellowstone River. The Yellowstone River Conservation District Council partnered with the U.S. Army Corps of Engineers to conduct a cumulative-effects study on the Yellowstone. For that study, the USGS calculated streamflow statistics for unregulated (no development) and...
Multi-century perspectives on current and future streamflow in the Missouri River Basin
The Missouri River system is the life-blood of the American Midwest providing water resources that drive agriculture, industry, hydroelectric power generation, and ecosystems. However, the Missouri River Basin (MRB) (Figure 1) is the only major river in the western U.S. for which hydrologic reconstructions from tree rings have not been generated in any systematic way. This knowledge gap is...
Flooding and High-Flow Conditions in Wyoming and Montana
The USGS monitors flood and high-flow conditions at more than 300 streamgages across Montana and Wyoming. Water level and flow information are used by the National Weather Service (NWS) to make accurate flood forecasts.
