Utah Water Science Center

Water Quality

The Utah Water Science Center collects water and sediment samples for chemical, physical, and biological analyses. Results of discrete sample analyses are stored in a national database that is a large and complex set of data. Nationally, more than 4.5 million records are stored in the database that have been collected by a variety of projects ranging from national programs to studies in small watersheds. 

At selected surface-water and groundwater sites, the USGS maintains instruments that continuously record physical and chemical characteristics of the water including temperature, specific conductance, pH, dissolved oxygen, and percent dissolved-oxygen saturation.

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...

Studies of Sources and Transport of Dissolved Solids (Salt) in the Colorado River Basin using the Spatially Referenced Regressions on Watershed Attributes (SPARROW) Model

The Upper Colorado River Basin (UCRB) encompasses about 112,000 mi2 and discharges more than 6 million tons of dissolved solids (salt) annually to the lower Colorado River Basin. It has been estimated...

Great Salt Lake Basins National Water Quality Assessment

The Great Salt Lake Basins (GRSL) National Water Quality Assessment (NAWQA) was one of 51 study units across the country. Started in 1998, the long-term goals of this program were 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 understanding of the primary factors affecting...
