Bird Banding Laboratory
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...
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...
BIBLIOGRAPHY OF REPORTS BY U.S. GEOLOGICAL SURVEY AUTHORS ABOUT THE WATER RESOURCES OF WYOMING
Since the late 19th Century, long before the first U.S. Geological Survey (USGS) office was opened in Wyoming, USGS scientists have been investigating the geology and water resources of the State and publishing their findings. The main product of all USGS work in Wyoming comprises the published reports of those investigations—mostly maps and book reports of the USGS, but also articles in...
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...
Development of Regional Curves Relating Bankfull-Channel Geometry and Discharge to Drainage Area for Hydrophysiographic Regions in Wyoming
The Watershed Program in cooperation with the U.S. Geological Survey (USGS), Wyoming Water Science Center developed regional curves that relate bankfull channel dimensions and discharge to drainage area for hydrophysiographic regions in Wyoming where data are currently lacking. Regional curves are useful aids for estimating bankfull discharge and related channel dimensions at ungaged sites,...
Muddy Creek Synoptic Study
A synoptic study was conducted June 27-July 1, 2010 in the Muddy Creek drainage basin. The Muddy Creek drainage basin is in an area of energy develoment in south-central Wyoming. The synoptic study was integrated in nature and included the collection of water-quality, basin-sediment, and macroinvertebrate samples. Sampling sites were located on Muddy Creek from the headwaters area to near...

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...

These models specifically include field data of locations with >40% cover of cheatgrass (presence) and <40% cover of cheatgrass (absence). Predictors included rasters derived from LandSat 8 imagery or from a digital elevation model.
National Water Information System web interface (NWISweb)
The National Water Information System (NWIS) web application provides access to real-time and historical surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.

Estimated Nitrogen and Phosphorus Input to Fish Creek Watershed
U.S. Geological Survey, in cooperation with Teton Conservation District (TCD), completed a study to identify and quantify nitrogen and phosphorus sources and inputs into the Fish Creek watershed. Geospatial datasets, values from literature reviews, water-quality data, and questionnaires distributed by TCD were used to identify locations of sources and to quantify nitrogen and phosphorus inputs...
Catchment-flowline network and selected model inputs for an enhanced and updated spatially referenced statistical assessment of dissolved-solids load sources and transport in streams of the Upper Colorado River Basin
This USGS data release consists of the synthetic stream network and associated catchments used to develop spatially referenced regressions on watershed attributes (SPARROW) model of dissolved-solids sources and transport in the Upper Colorado River Basin as well as geology and selected Basin Characterization Model (BCM) data used as input to the model.

Small variations in the density of the earth’s crust—undetectable to humans without sensitive instruments—influence where earthquakes may occur in the central United States. These new findings from the U.S. Geological Survey, published today in Nature Communications, may allow scientists to map where future seismicity in the center of the country is most likely.
The U.S. Geological Survey and the Bureau of Land Management today released a collaborative report with new information and tools to support effective management of millions of acres of BLM public lands. The report underscores the value of a landscape approach to management, and shows that the BLM manages some of the largest areas of intact public lands in the west.
Helpful new information for anyone designing structures over or near water, managing water distribution, or interested in the flow of local streams.
A new U.S. Geological Survey publication and model can be applied by multiple entities to better understand flow, quantity, sources and sinks of groundwater in the Northern High Plains Aquifer, which covers approximately 100,000 square miles across Nebraska, South Dakota, Kansas, Colorado and Wyoming.

Offspring of grizzly bear mothers with a history of human-bear conflicts are more likely to be involved in human-bear conflicts than offspring of mothers without a history of human-bear conflicts, according to a new study.
New study investigates groundwater from the air
Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study by the U.S. Geological Survey and the Bureau of Reclamation.
At the request of the Bureau of Land Management, USGS has released an assessment of mineral resources in six Western states.
Future groundwater replenishment in the Upper Colorado River Basin may benefit from projected increases in future basin-wide precipitation under current climate projections, according to a recent study by the U.S. Geological Survey and Bureau of Reclamation.
