Science and Products
Salinity
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 that between 32 and 45...
Managed Aquifer Recharge
Sand Hollow Reservoir in Washington County, Utah, was completed in March 2002 and is operated for both surface-water storage and managed aquifer recharge via infiltration from surface basin spreading to the underlying Navajo Sandstone. From 2002 through 2014, about 216,000 acre-feet were diverted from the Virgin River to Sand Hollow Reservoir, and about 127,000 acre-feet of water seeped beneath...
Great Basin Carbonate and Alluvial Aquifer System (GBCAAS)
The Great Basin Carbonate and Alluvial Aquifer System (GBCAAS) was part of the federally-funded USGS Water Availability Program. Specific objectives of the study included quantifying current ground-water resources, evaluating how those resources have changed over time, and developing tools to assess system responses to stresses from future human uses and climate variability. The GBCAAS study...
