A study was done during 1994 on selected reaches of the Virgin River from Ash Creek to Harrisburg Dome in the central Virgin River area, Washington County, Utah, to determine gain or loss of flow in the river from seepage. There was a net gain of 10.7 cubic feet per second in the selected 14-mile section of the Virgin River near Hurricane, Utah. The two upstream reaches of this section...

The U.S. Geological Survey (USGS) has been collecting hydrologic data relating to the occurrence, quantity, and quality of water resources in Utah since 1889. The USGS maintains a network of about 200 gaging stations on rivers, streams, lakes, and reservoirs in Utah and parts of Wyoming, Idaho, and Arizona and monitors about 1,100 wells throughout the State (fig. 1). Within this network...

This is the thirty-second in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Department of Natural Resources, Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions. This report, like the others in the...

A three-dimensional, finite-difference, numerical model was developed to simulate ground-water flow in the basin-fill material in Salt Lake Valley, Utah. The model was calibrated to steady-state and transient-state conditions. The steady-state simulation was developed and calibrated using hydrologic data defining average conditions for 1968. The transient-state simulation was developed...

Ground-water recharge to basin-fill aquifers from unconsumed irrigation water in the western United States is being reduced as irrigators convert to more efficient irrigation systems. In some areas, these changes in irrigation methods may be contributing to ground-water-level declines and reducing the quantity of water available to downgradient users. The components of the water budget...

The hydrologic system in the central Sevier Valley, and more specifically the Sevier-Sigurd basin, is a complex system in which surface- and ground-water systems are interrelated. Seepage from an extensive irrigation system is the primary source of recharge to the basin-fill aquifer in the Sevier-Sigurd basin. Water-quality data indicate that inflow from streams and subsurface inflow...

The surface-and ground-water hydrology of Sanpete Valley and the San Pitch River drainage basin, Sanpete and Juab Counties, Utah, was studied to define the current conditions of the hydrologic system, to detect causes for downstream changes in water quality in the San Pitch River and in areas of high concentration of dissolved solids in ground water, and to determine the possible effects...

Ground water is an important freshwater source for domestic and livestock uses in southeastern Utah because of the arid climate and unavailability of surface water from the San Juan River. The study area includes about 1,200 square miles in the southeastern corner of Utah (fig. 1). Precipitation on mountainous areas north, south, and east of the study area (fig. 2) seeps into the Navajo...

This is the thirty-first in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions. This report, like the others in the series, contains information on well

A hydrologic investigation of Cache Valley was done to better understand the ground-water system in unconsolidated basin-fill deposits and the interaction between ground water and surface water. Ground-water recharge occurs by infiltration of precipitation and unconsumed irrigation water, seepage from canals and streams, and subsurface inflow from adjacent consolidated rock and adjacent

Communities in southeastern Tooele Valley, Utah, are growing, and future demand for water is expected to increase. To prepare for this demand, local surface- and ground-water resources were evaluated. Average streamflow in Settlement, Middle, and Soldier Canyons is about 6,000, 2,100, and 3,900 acre-feet per year, respectively. The combined average perennial streamflow of Pine, Pole...
