Hydrology and simulation of ground-water flow in the Tooele Valley ground-water basin, Tooele County, Utah

Hydrogeologic and geochemical characterization of groundwater resources in Rush Valley, Tooele County, Utah

“…7) using flow nets (Domenico and Schwartz, 1998) constructed between the 4,900-and 5,000-ft water-level contours in both areas and the median T value (290 ft 2 /d) for basin-fill deposits (table 3). These estimates fall 1964 1965 1966 1967 1968 1969 1970 1971 1972 1973 1974 1975 1976 1977 1978 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 within the range of previous estimates of discharge from Rush to Cedar Valley and from Rush to Tooele Valley, which range from "small" to about 5,000 acre-ft/yr (Thomas, 1946;Gates, 1965;Hood andothers, 1969, Razum andSteiger, 1981;and Stolp and Brooks, 2009) The estimate of subsurface discharge from Rush to Cedar Valley is in agreement with that made by Jordan and Sabah as part of an ongoing study (L. Jordan, written commun., 2010). The estimate of subsurface discharge from Rush to Tooele Valley is in agreement with the "small but significant" amount postulated by Hood and others (1969) but less than that used in the later modeling study by Razum and Steiger, 1981.…”

“…Both of these valleys have limited water resources and are closed to new groundwater appropriations. Previous studies have shown the three valleys to be hydraulically connected, with groundwater movement in the basin-fill aquifer out of Rush Valley and into Tooele and Cedar Valleys, both at lower altitudes (Hood and others, 1969;Razem and Steiger, 1981;Stolp, 1994;Lambert and Stolp, 1999;Stolp and Brooks, 2009). Development of groundwater resources in Rush Valley recently has been proposed to supply water to the growing populations in Tooele and Cedar Valleys.…”

“…A long-term monitoring and sampling program began in 1998 to evaluate groundwater movement and water quality at the Deseret Chemical Depot (DCD), which occupies approximately 30 mi 2 in east-central Rush Valley (North Wind Inc., 2008). Water-level and groundwater-geochemistry data have been collected from northern Rush Valley as part of several USGS studies of Tooele Valley (Stolp, 1994;Lambert and Stolp, 1999;Stolp and Brooks, 2009). Jordan and Sabah of the Utah Geological Survey are currently investigating the hydrology of Cedar Valley to the east of Rush Valley and developing a numerical groundwater-flow model for that valley that incorporates an estimate of subsurface flow from Rush Valley to Cedar Valley (L. Jordan, oral commun., 2010).…”

Analyses of infrequent (quasi-decadal) large groundwater recharge events in the northern Great Basin: Their importance for groundwater availability, use, and management

“…For example, a water level measured in March 1983 is affected by precipitation during water year 1982, which spans the period 1 October 1981 to 30 September 1982. Precipitation in October through April is often in the form of snow which either replenishes the soil moisture if it melts quickly, or accumulates as snow and becomes recharge and runoff from snowmelt in May through July [ Stolp and Brooks , ]. This recharge and runoff plus any precipitation from May to September affect spring season water levels the following year [ Stolp and Brooks , ].…”

America's water: Agricultural water demands and the response of groundwater

“…Over a third of global freshwater withdrawals are sourced from aquifers [Stolp and Brooks, 2009;Siebert et al, 2010]. In the conterminous United States (CONUS) over 40% of water consumed for irrigation, livestock, and domestic water is sourced from groundwater [Maupin et al, 2014], and it is almost exclusively drawn from wells that are deeper than 30 m [e.g., Nolan and Hitt, 2006].…”
