Great Salt Lake (GSL) is a designated Site of Hemispheric Importance for migratory birds by the Western Hemisphere Shorebird Reserve Network. Elevated mercury (Hg) and methylmercury (MeHg) levels related to current inputs and past industrial contamination pose a potential threat to GSL biota, in addition to waterfowl hunters that utilize GSL and surrounding wetland areas. Sediments...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

This data release contains two sets of estimated values at selected sites within the Colorado River Basin: 1) daily specific conductance at 143 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); and 2) daily baseflow discharge at 100 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022). The estimates of daily baseflow discharge will be used as input...

The United States Geological Survey (USGS) collected a total of 63 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels, nearby outcrops, and background areas representative of the undisturbed lithology within the Free Coinage and Third Term mining districts in the Stansbury Mountains (Krahulec, 2018). The samples were sieved to obtain the less than 177 micron...

The United States Geological Survey (USGS) collected a total of 179 samples of surficial sediment from abandoned mine wastepiles, ephemeral channels, nearby outcrops, and background areas representative of the undisturbed lithology within the Silver Island and Crater Island mining districts (Krahulec, 2018).The samples were sieved to obtain the less than 177 micron fraction. Geochemical...

From October 2017 to June 2018, the United States Geological Survey (USGS) collected 101 surficial sediment samples from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology in the Browns Park mining district of northeastern Utah. Additionally, twelve sediment samples were collected in drainages...

The Spor Mountain study area is located in the Spor Mountain Range, approximately 42 miles northwest of Delta, Utah. Mining in the Spor Mountain district began in the 1940s and continues to present day. Fluorspar, uranium, and beryllium are the main ores mined(Ege, 2005). From August through September 2013, the United States Geological Survey (USGS) collected a total of 73 samples from...

This data release contains three sets of estimated values at selected sites within the Colorado River Basin: 1) daily specific conductance at 143 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); 2) daily baseflow discharge at 100 sites in the Upper Basin and 3 sites in the Lower Basin (WY 1980-2022); and 3) seasonal baseflow discharge and baseflow dissolved solids...

This model archive summary documents the sediment acoustic index model for suspended-sediment concentration developed to compute 15-minute suspended sediment concentration for the U.S. Geological Survey (USGS) station, San Juan River near Bluff, UT (USGS ID: 09379500) from May 2, 2018, onward. This is the first model developed for the site to compute continuous suspended sediment...

This U.S. Geological Survey (USGS) Data Release provides salinity and density data collected at Great Salt Lake (GSL), Utah monitoring locations during 2021–2022. Temperature, specific conductance, and dissolved oxygen were collected using an In-Situ AquaTROLL 600. Sample density was measured using an Anton Paar DMA 35Ex at 5° increments between 5° and 40° C. Practical salinity was...

This U.S. Geological Survey (USGS) Data Release provides vertical water-quality profiles collected at Great Salt Lake, Utah monitoring sites during 1995–2000 and 2011–2022. Data were collected using an In-Situ Multi-Parameter TROLL 9500, In-Situ AquaTROLL 500, In-Situ AquaTROLL 600, or YSI EXO2 Multiparameter Sonde. Recorded parameters include water temperature, specific conductance...

This data release contains model code and input data for, and predictions from, both a dynamic stream dissolved solids and a static baseflow dissolved solids SPARROW (SPAtially Referenced Regression On Watershed attributes) model of the Upper Colorado River Basin for water years 1986-2017. Input data includes information on dissolved solids sources, landscape transport characteristics...
