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. High-flow conditions are expressed as percentiles comparing current (within the past few hours) instantaneous flow to historical daily mean flow for ...
Characterization of Fish Creek and Evaluation of Nutrient Inputs to Watershed
Fish Creek, an approximately 15-mile long tributary of the Snake River, is located in Teton County in western Wyoming near the town of Wilson. Local residents began observing an increase in the growth of algae and aquatic plants in Fish Creek in about 2000.
Geospatial Research and Development to Understand Hydrologic Processes
All natural phenomena have a spatial component. Remote sensing, GIS, and geostatistical methods can be used to evaluate the spatial components of hydrologic phenomena and understand characteristics, such as water quality, streamflow, and hydraulics.
Interagency Grizzly Bear Study Team
The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy...
Impacts of Disease on Wolves in Yellowstone National Park
In 1995 and 1996, wolves were reintroduced into the Northern Rockies where they have since established and spread. Within Yellowstone National Park, one of the core protected release sites, the unmanaged population steadily increased to high densities, producing a large wolf population susceptible to infections such as canine parvovirus (CPV), canine distemper virus (CDV) and sarcoptic mange...
Brucellosis
Brucellosis is a nationally and internationally regulated disease of livestock with significant consequences for animal health, public health, and international trade.
Land Treatment Digital Library
The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The...
Reconstructing Flow History From Riparian Tree Rings
Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We also use downscaled climate...
USGS Data at Risk: Expanding Legacy Data Inventory and Preservation Strategies
As one of the largest and oldest science organizations in the world, USGS has produced more than a century of earth science data, much of which is currently unavailable to the greater scientific community due to inaccessible or obsolescent media, formats, and technology. Tapping this vast wealth of “dark data” requires 1) a complete inventory of legacy data and 2) methods and tools to...
Rocky Mountain Regional Snowpack Chemistry Monitoring Study
Snowpacks collect atmospheric deposition throughout the snowfall season and offer a unique opportunity to obtain a composite sample of the chemistry of most of the annual precipitation at high elevations [> 1,800 meters]. The purpose of the snowpack network is to determine annual concentrations and depositional amounts of selected nutrients and other constituents in snow resulting from...
Wyoming Groundwater-Quality Monitoring Network
A wide range of activities have the potential to contaminate groundwater. In addition, several naturally-occurring constituents can limit the suitability of groundwater for some uses. The State of Wyoming has established rules and programs to protect groundwater quality, as well as agencies to implement the rules and programs. The Wyoming Groundwater-Quality Monitoring Network (WGQMN) is one...
Riparian Ecology
Riparian ecologists in the AS Branch study interactions among flow, channel change, and vegetation along rivers across the western United States and worldwide. Our work focuses on issues relevant to the management of water and public lands, including dam operation, climate change, invasive species, and ecological restoration. Investigations take place on a range of scales. For example,...

Description of core collected during installation of a Wasatch aquifer monitoring well in the Green River Basin, Sublette County, Wyoming
A monitoring well was installed in the Wasatch aquifer in the Green River Basin, Sublette County, Wyoming in August 2015. Core collected during drilling activities was described to a depth of 170 feet. The data release contains a detailed description of the lithology and physical characteristics of the core sections, as well as numerous photographs. The data release was produced in complian...
Digital map of hydrothermal alteration type, key mineral groups, and green vegetation of the northwestern United States derived from automated analysis of ASTER satellite data
Mineral groups identified through automated analysis of remote sensing data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) were used to generate a map showing the type and spatial distribution of hydrothermal alteration, other exposed mineral groups, and green vegetation across the northwestern conterminous United States. Boolean algebra was used to
