Great Basin Studies
Great Basin Studies
The Great Basin is characterized by numerous arid to semi-arid basins with unconsolidated alluvial aquifers separated by mountain ranges often comprised of carbonate aquifers. Population is concentrated within 100 miles of Salt Lake City and in the Las Vegas area and is growing rapidly. In the less populated areas, ranching and irrigated farming are the main economies.

Prey Availability
Migratory wildlife need to balance the benefits of migration and reproduction with the physiological costs. This is particularly challenging in dynamic environments like wetlands, where food levels can vary greatly from year to year. For shorebirds in the Great Basin region, saline or terminal lakes provide essential habitats during their annual life cycle. To understand how changes in hydrology...

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 visitors...
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...
