Aquifer systems in the Great Basin region of Nevada, Utah, and adjacent states; summary report

An update of the Death Valley regional groundwater flow system transient model, Nevada and California

“…The rocks of the LCA have an aggregate thickness of as much as 8,000 m and are generally the most permeable rocks in the region (Bedinger and others, 1989b;Belcher and others, 2001). Where hydraulically connected, the carbonate rocks provide a path for interbasin flow (Harrill and others, 1988;D'Agnese and others, 1997;Harrill and Prudic, 1998). In the vicinity of the NNSS, the LCA is overlain by the upper siliciclastic-rock confining unit (UCCU; table 1).…”

“…Overlying the low-permeability hydraulic basement is the lower carbonate-rock aquifer (LCA, table 1), a major regional aquifer for the eastern two-thirds of the Great Basin, including the Death Valley region (Winograd and Thordarson, 1975;Bedinger and others, 1989a;Harrill and Prudic, 1998). The rocks of the LCA have an aggregate thickness of as much as 8,000 m and are generally the most permeable rocks in the region (Bedinger and others, 1989b;Belcher and others, 2001).…”

Field guide to geologic excursions in southwestern Utah and adjacent areas of Arizona and Nevada

“…(Dixon and Katzer, 2002). The basins to the west of the Tule Desert, are part of the carbonate aquifer of the White River ground-water flow system (Harrill and others, 1988;Dettinger, 1989;Dettinger and others, 1995;Prudic and others, 1995;Schmidt and Dixon, 1995;Brothers and others, 1996;Thomas and others, 1996;Burbey, 1997;Harrill and Prudic, 1998). Ground water travels south-southwest in both flow systems (Dixon and Katzer, 2002).…”

Trends in streamflow on the Humboldt River between Elko and Imlay, Nevada, 1950-99

“…Only Paradise Valley north of Winnemucca had annual estimates that extended for 1950-99 (Prudic and Herman, 1996; and crop inventories from NDWR). Annual ground-water withdrawals in other areas of the Humboldt River Basin above Imlay were estimated from previous reports (Eakin, 1961;Zones, 1961;Eakin, 1962;Cohen, 1963;Crosthwaite, 1963;Cohen, 1964;Eakin and others, 1965;Everett and Rush, 1966;Rush and Everett, 1966;Eakin and others, 1976;and Harrill and Prudic, 1998); from maps and air photos showing irrigated acreages during the mid-1970's, from crop inventories compiled annually by NDWR since the early 1980's, and from well drillers' reports …”
