Ground water conditions in Tooele Valley, Utah, 1976-78

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.…”

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

“…The purpose of this report is to present a conceptual model and water budget of the Tooele Valley ground-water basin and to describe a new three-dimensional numerical ground-water flow model of the basin developed as part of the study. The results presented in this report represent an incremental improvement in understanding the hydrologic concepts first presented by Carpenter (1913) and refined by Thomas (1946), Gates (1965), Razem and Steiger (1981), and Lambert and Stolp (1999). Improvements include a more comprehensive description of ground-water recharge using a distributed net infiltration approach and a more detailed description of ground-water movement and residence times.…”

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

“…Aquifer tests were done to quantify the hydrologic properties of the basin-fill material, and water-quality data were collected to define areas of poor-quality water in the valley. Razem and Steiger (1981) updated the water budget for the principal aquifer system developed by Gates (1965) on the basis of longer term surface-and ground-water data, additional aquifer tests, and a more detailed analysis of evapotranspiration. Concurrent with the Razem and Steiger (1981) study, test holes were drilled in Tooele Valley to obtain hydrologic and geologic information on basin-fill material (Ryan and others, 1981).…”
