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) (fig. 1). Its calcium carbonate type water is a brilliant green-blue color that, in combination with sandy beaches and easy access, draws thousands...
Density-stratified flow events in Great Salt Lake, Utah, USA: implications for mercury and salinity cycling
Density stratification in saline and hypersaline water bodies from throughout the world can have large impacts on the internal cycling and loading of salinity, nutrients, and trace elements. High temporal resolution hydroacoustic and physical/chemical data were collected at two sites in Great Salt Lake (GSL), a saline lake in the western USA, to...
Naftz, David L.; Carling, Gregory T.; Angeroth, Cory; Freeman, Michael; Rowland, Ryan; Pazmiño, Eddy Monitoring change in Great Salt Lake
Despite the ecological and economic importance of Great Salt Lake, only limited water quality monitoring has occurred historically. To change this, new monitoring stations and networks—gauges of lake level height and rate of inflow, moored buoys, and multiple lake-bottom sensors—will provide important information that can be used to make informed...

Assessment of potential migration of radionuclides and trace elements from the White Mesa uranium mill to the Ute Mountain Ute Reservation and surrounding areas, southeastern Utah
In 2007, the Ute Mountain Ute Tribe requested that the U.S. Environmental Protection Agency and U.S. Geological Survey conduct an independent evaluation of potential offsite migration of radionuclides and selected trace elements associated with the ore storage and milling process at an active uranium mill site near White Mesa, Utah. Specific...
Naftz, David L.; Ranalli, Anthony J.; Rowland, Ryan C.; Marston, Thomas M. Ground-water conditions in Utah, spring of 2009
This is the forty-sixth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Department of Natural Resources, Division of Water Resources and Division of Water Rights, and the Utah Department of Environmental Quality, Division of...

Physical and Chemical Water-Quality Data from Automatic Profiling Systems, Boulder Basin, Lake Mead, Arizona and Nevada, Water Years 2001-04
Water-quality profile data were collected in Las Vegas Bay and near Sentinel Island in Lake Mead, Arizona and Nevada, from October 2000 to September 2004. The majority of the profiles were completed with automatic variable-buoyancy systems equipped with multiparameter water-quality sondes. Profile data near Sentinel Island were collected in August...
Rowland, Ryan C.; Westenburg, Craig L.; Veley, Ronald J.; Nylund, Walter E. Water resources data, Nevada, water year 2003
Water-resources data for the 2003 water year for Nevada consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; precipitation; and water levels in wells. This report contains discharge records for 182 streamflow-gaging stations on streams, canals and drains; Discharge data...

Selenium contamination and remediation at Stewart Lake Waterfowl Management Area and Ashley Creek, middle Green River basin, Utah
Selenium is an element required in trace amounts for human and animal health, but it can cause health problems for livestock, wildlife, and humans when ingested in higher-than-required concentrations. Incidences of mortality, birth defects, and reproductive failure in waterfowl were discovered at Kesterson National Wildlife Refuge, San Joaquin...
Rowland, Ryan C.; Stephens, Doyle W.; Waddell, Bruce; Naftz, David L. Hydrologic, sediment, and biological data associated with irrigation drainage in the middle Green River basin, Utah and Colorado, water years 1991-2000
Hydrologic, sediment, and biological data were collected in the middle Green River basin in eastern Utah from 1991 to 2000 in an effort to monitor the effects of irrigation drainage on wetland areas and streams, aid in the development of remediation plans, and evaluate the effectiveness of selenium remediation efforts at Stewart Lake Waterfowl...
Rowland, Ryan C.; Allen, David V.; Stephens, Doyle W.; Yahnke, James W.; Darnall, Nathan L.; Waddell, Bruce Selected hydrologic data for the field demonstration of three permeable reactive barriers near Fry Canyon, Utah, 1996-2000
Three permeable reactive barriers (PRBs) were installed near Fry Canyon, Utah, in August 1997 to demonstrate the use of PRBs to control the migration of uranium in ground water. Reactive material included (1) bone-char phosphate, (2) zero-valent iron pellets, and (3) amorphous ferric oxyhydroxide coated gravel. An extensive monitoring network was...
