The electric power generation potential from identified geothermal systems is 9,057 Megawattselectric (MWe), distributed over 13 states. Undiscovered resources are estimated to provide an additional 30,033 MWe.
We estimated mean undiscovered volumes of 3.65 billion barrels of oil, 1.85 trillion cubic feet of associated dissolved natural gas, and 148 million barrels of natural gas liquids in this area using a geology-based assessment methodology.
We estimated a mean of 989 billion cubic feet of undiscovered natural gas, a mean of 72 million barrels of undiscovered oil, and a mean of 13 million barrels of undiscovered natural gas liquids in this area.
We estimated mean undiscovered volumes of 3.8 billion barrels of undiscovered oil, 3.7 trillion cubic feet of associated/dissolved natural gas, and 0.2 billion barrels of undiscovered natural gas liquids using a geology-based assesment methodology.
We estimated in-place resources of 1.07 trillion short tons of coal in this area using a geology-based assessment methodology. Of that total, recoverable coal was 162 billion tons, 25 billion economically recoverable.
We estimated mean undiscovered volumes of 7.4 billion barrels of oil, 6.7 trillion cubic feet of associated/dissolved natural gas, and 0.53 billion barrels of natural gas liquids in this area using a geology-based assessment methodology.
Small wetlands in this large area have hosted migratory birds for a long time, but with changes in agricultural practice and regional climate those habitats may not remain hospitable to the wild populations.
Overview of interdisciplinary research studies in Glacier National Park to understand how this mountain wilderness responds to present climatic variability and other external stressors, such as air pollution, and links to detailed reports.
Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
Population size, foaling, deaths, age structure, sex ratio, age-specific survival rates, and more over a 14 year time span. This information will help land and wildlife managers find the best maintenance and conservation strategies.
To better understand the exchange of groundwater and surface water, we coupled groundwater monitoring at the stream bank with nearby gages in the stream. Describes the procedure and results from several areas.
Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Description of research program for immediate and long-term management of grizzly bears (Ursus arctos horribilis) inhabiting the Greater Yellowstone Ecosystem. Includes links to reports in PDF format and cooperating organizations.
Description of project monitoring the status of Greater Glacier National Park Area's grizzly bear and black bear populations using genetic techniques on DNA from bear hair or scats without handling bears, with photos and discussion of methods.
Project to assess the grizzly bear population size, trend, and survival in the Northern Continental Divide Ecosystem (NCDE) in Montana to improve the long-term survival for this threatened species. With description, DNA identification means and photos.
Northern Rocky Mountain Science Center (NRMSC) based at Bozeman, Montana conducts research to help natural resources management in the Northern Rocky Mountains with field stations at West Glacier and Missoula. Links to staff, programs, and partners.
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
One of the greatest challenges for conserving grassland, prairie scrub, and shrub-steppe ecosystems is maintaining prairie dog populations across the landscape. Of the four species of prairie dogs found in the United States, the Utah prairie dog (Cynomys
Change in streams accompanying land and water use may affect benthic invertebrate assemblage composition and structure through changes in density of invertebrates or taxa richness, the number of different species living in the stream.
A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2007 (October 1, 2006 to September 30, 2007) in the context of the 78-year period 1930-2007.

A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2010 (October 1, 2009 to September 30, 2010) in the context of the 81-year period 1930-2010.
A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2011 (October 1, 2010 to September 30, 2011) in the context of the 82-year period 1930-2011.
About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.
Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
This updated subset of USGS streamgages for which the streamflow primarily reflects prevailing meteorological conditions for specified years, screened to exclude sites where human activity affects the natural flow of the watercourse.
