Ground water in the Navajo Sandstone near Caineville, Wayne County, Utah, was studied during 1975-77 as part of an investigation of water in bedrock in the lower Dirty Devil River basin area. The purpose of the study near Caineville was to determine the water-bearing properties of the Navajo by utilizing data obtained mainly during test drilling and aquifer testing by the Intermountain...

The circulation of water in Flaming Gorge Reservoir is caused chiefly by insolation, inflow-outflow relationships, and wind, which is significant due to the geographical location of the reservoir. During 1970-75, there was little annual variation in the thickness, dissolved oxygen, and specific conductance of the hypolimnion near Flaming Gorge Dam. Depletion of dissolved oxygen occurred

The water-quality reconnaissance in the Dirty Devil River basin, covered an area of about 4,300 square miles (11,100 square kilometers). were obtained by the U.S. Geological Survey one or more times at 104 during the period July 1975 to September 1976; and during visits to 34 sites during the same period, the streams were dry.

The Wasatch Plateau-Book Cliffs%area as used in this report consists of about 8,000 square miles in east-central Utah. The major geographic features included in the area are the Wasatch Plateau, Book Cliffs, San Rafael Swell, Price River basin, and a small part of the Green River basin (pl. 1). The area is defined by approximate drainage-divide boundaries in the Wasatch Plateau and Book...

This study covers about 1,000 mi2 (2,600 km2 ) of the southern Raft River drainage basin in south-central Idaho and northwest Utah. The main area of interest, approximately 200 mi2 (520 km2 ) of semiarid agricultural and rangeland in the southern Raft River Valley that includes the known Geothermal Resource Area near Bridge, Idaho, was modelled numerically to evaluate the hydrodynamics...

This report summarizes ground-water availability in the lower Colorado region and discusses the potential for greater ground-water development and increased efficiency of water use. The climate in the most highly developed southwestern part of the region is warm and dry and that in the northeastern part is cool and moist to dry. Although the regional average annual precipitation is only...

This report is the fifteenth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, prepared 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 (see References, p. 13), contains...

The Parowan-Cedar City drainage basin, Iron County, Utah, includes about 1,100 mi2 (square miles)(2,800 km2 [square kilometers])--520 mi2 (1,300 km2) in the Parowan basin and 580 mi2 (1,500 km2) in the Cedar City basin. Parowan and Cedar City Valleys are structural depressions formed by northeast-trending faults. Parowan Valley is essentially a closed basin, whereas Cedar City Valley is...

During September 5-7, 1970, unusually large floods occurred in the mountains of central Arizona and in the Four Corners area of Arizona, Utah, Colorado, and New Mexico. Flooding also occurred in southern and northeastern Arizona. The record-high rainfall of September 5 occurred when a mass of moist tropical air from Pacific storm Norma collided with a cold front from the northwest. A new...

The northern Uinta Basin area covers about 5,200 square miles (13,470 square kilometers) in northeastern Utah and northwestern Colorado. Much of the lowlands are arid to semiarid, but the highest parts of the Uinta Mountains have a humid climate. During 1941-70, the average annual precipitation ranged from less than 8 inches (203 millimeters) in the lowest part of the area at the Green...

The central Virgin River basin, Utah, includes about 1,000 square miles (2,600 square kilometers) in the drainage basin of the Virgin River downstream from the Hurricane Cliffs. The Navajo Sandstone of Late Triassic(?) and Jurassic age crops out in 234 square miles (606 square kilometers) of the basin and underlies younger rocks in about 450 square miles (1,200 square kilometers) of the...

The Dugway Valley-Government Creek area covers about 890 square miles (2,300 square kilometers) in west-central Utah. Total annual precipitation on the area averages about 380,000 acre-feet (470 cubic hectometers). Most streams are ephemeral except for a few in their upper reaches--all are ephemeral below the altitude of about 6,000 feet (1,830 meters). Surface-water development and use...
