Carbon County Water Resources Study

In cooperation with the Wyoming State Engineer, the USGS conducted a study of the water resources of Carbon County, Wyoming. This study followed the general plan of previous "County Studies". Surface water and ground water resources were evaluated through a combined approach that analyzed and summarized existing data and, as a consequence of the data analysis, identified key data gaps and...

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...

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 ...

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...

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...

The Colorado River system provides about 35 million Americans with a portion of their water supply. It irrigates 5½ million acres of land in the West and provides water to tribes, parks, and wildlife. The system serves parts of seven States and Mexico—but reservoir levels have crept lower over the past several years, sparking questions about how much water remains and who will have access.

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.
