Quantifying Nutrient Mass and Internal Cycling in Great Salt Lake
The Great Salt Lake (GSL) is an indispensable economic and ecological resource. It provides critical habitat and food for millions of migratory birds, and generates nearly $200 million per year from recreational activities and the brine shrimp harvest industry (Bioeconomics, 2012). These uses, habitat and aquaculture, rely on a balanced supply of nutrients in the Great Salt Lake to support...
Past Perspectives of Water in the West
In the intermountain west, seasonal precipitation extremes, combined with population growth, are creating new challenges for the management of water resources, ecosystems, and geologic hazards. This research contributes a comprehensive long-term context for a deeper understanding of past hydrologic variability, including the magnitude and frequency of drought and flood extremes and ecosystem...
Bear Lake Water Quality
Bear Lake, located approximately 50 kilometers (km) northeast of Logan, Utah, straddles the Utah-Idaho border and is nestled in a graben valley between the Bear Lake Plateau on the east and the Bear River Range on the west (Reheis and others, 2009). Its calcium carbonate type water is a brilliant green-blue color that, in combination with sandy beaches and easy access, draws thousands of...
Groundwater Conditions in Utah
Small amounts of groundwater can be obtained from wells throughout most of Utah, but large amounts that are of suitable chemical quality for irrigation, public supply, or industrial use generally can be obtained only in specific ares. Most wells in Utah yield water from unconsolidated basin-fill deposits, and most are in intermountain basins that have been partly filled with rock materials...
Streamflow Information Program
The U.S. Geological Survey (USGS) operates and maintains a national network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and effective...

Domestic Wells in the United States
Domestic wells provide drinking water supply for approximately 40 million people in the United States. Knowing the location of these wells, and the populations they serve, is important for identifying heavily used aquifers, locations susceptible to contamination, and populations potentially impacted by poor-quality groundwater.
Data for assessing the susceptibility of groundwater used for drinking water supply from selected principal aquifers of the Western United States, 2004-2018
Groundwater age distribution and susceptibility to natural and anthropogenic contaminants were assessed for selected principal aquifers of the Western United States: the Central Valley aquifer system (CVAL), the Basin and Range basin-fill aquifers (BNRF), the Rio Grande aquifer system (RIOG), the High Plains aquifer (HPAQ), the Columbia Plateau basaltic-rock aquifers (

This map shows the provinces assessed by the USGS for undiscovered oil and gas resources.
The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.
Topographic maps are a signature product of the USGS. They were essential for integrating and analyzing place-based information, and were widely used by receationalists. After 125-year legacy of topographic mapping (1884-2009), the USGS embarked on an innovative future of integrating historical maps with computer-generated maps from a national geographical information system (GIS) database.
