Ground-water resources of the Parowan-Cedar City drainage basin, Iron County, Utah

The Parowan-Cedar City drainage basin, Iron County, Utah, includes about 1,100 mi 2 (square miles)(2,800 km 2 [square kilometers])--520 mi 2 (1,300 km 2 ) in the Parowan basin and 580 mi 2 (1,500 km 2 ) 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 drained by two gaps in the mountains bordering the west side of the valley, and a small part of Cedar City Valley is drained at a gap at the south end. Water flowing into the basin from the highlands to the east is used to irrigate lands near Cedar City, Parowan, Paragonah, and Summit. The surface-water outflow from the basin is negligible.

Ground-water reconnaissance of the central Weber River area, Morgan and Summit Counties, Utah

During July 1978 to June 1980, the U.S. Geological Survey conducted a reconnaissance of ground-water conditions and ground- and surface-water relationships in the central Weber River area. This reconnaissance was done in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The study area is a series of mountain valleys along the Weber River in the Wasatch Ranqe and between the Wasatch Range and the Uinta Mountains in north-central Utah (fig. 1). As defined for this study, the area includes the Weber River drainage from Hoytsville, just south of Coalville, to the western boundary of Morgan County at the western front of the Wasatch Range (pl. 1). The East Canyon Creek tributary drainage is included from the Weber River to the Morgan County-Summit County line. The study focused on the major valleys along and tributary to the Weber River with less emphasis on the upland tributary areas.

Hydrologic evaluation of the upper Duchesne River Valley, northern Uinta Basin area, Utah

The upper Duchesne River valley was studied during 1971-74 as part of an investigation of the northern Uinta Basin area, Utah and Colorado. The purpose of the study was to determine the relation of ground water to surface water, to estimate the quantity of ground water that moves to the Duchesne River, and to assess the probable effect of increased ground-water withdrawal on streamflow.

Water resources of the northern Uinta Basin area, Utah and Colorado, with special emphasis on ground water supply

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 River to more than 38 inches (965 millimeters) in the high west-central Uinta Mountains.

Ground-water hydrology and projected effects of ground-water withdrawals in the Sevier Desert, Utah

The principal ground-water reservoir in the Sevier Desert is the unconsolidated basin fill. The fill has been divided generally into aquifers and confining beds, although there are no clearcut boundaries between these units--the primary aquifers are the shallow and deep artesian aquifers. Recharge to the ground-water reservoir is by infiltration of precipitation; seepage from streams, canals, reservoirs, and unconsumed irrigation water; and subsurface inflow from consolidated rocks in mountain areas and from adjoining areas. Discharge is by wells, springs, seepage to the Sevier River, evapotranspiration, and subsurface outflow to adjoining areas.

Ground-water resources of northern Utah Valley, Utah

An evaluation was made of the ground-water resources of northern Utah Valley, Utah, to describe the ground-water system and to document changes in ground-water conditions since 1963. The principal ground-water reservoir is in basin-fill deposits. It consists of three major confined aquifers and an unconfined aquifer in pre-Lake Bonneville deposits along the mountains that adjoin the valley. The principal ground-water reservoir contains about 10 million acre-feet of recoverable water.

Seepage study of canals in Beaver Valley, Beaver County, Utah

A study of the gains or losses of nine canals near Beaver, Utah, was made to aid in the water allocation of the canal systems. The canals included in this study are Manderfield Ditch, Last Chance Canal, Christiansen Ditch, Mammoth Canal, City Ditch, Owens Ditch, South Field Ditch, Patterson Ditch and Aberdare Canal. Four sets of seepage measurements were made during 1974, but flow was observed in all nine canals only during the set of measurements made in June. Adjustments for fluctuations in flow in the canals were made from information obtained from water-stage recorders operated at selected locations along the canals during the time of each seepage run.

Seepage study of the Sevier Valley-Piute Canal, Sevier County, Utah

A study of the gains or losses of the Sevier Valley-Piute Canal from near Joseph to near Aurora, Sevier County, Utah, was made to aid in water allocation for the canal system. Four sets of seepage measurements were made in 1976, with the three most representative being used in the analysis. Adjustments for fluctuations in flow in the canals were made from information obtained from water-stage recorders operated at selected locations along the canal during the time of each seepage run.

Seepage study of the West Side and West Canals, Box Elder County, Utah

A study of the gains or losses of the West Side and West Canals from Cutler Reservoir to near Penrose, Box Elder County, Utah, was made to aid in water allocation for the canal system. Four sets of seepage measurements made in 1978 were used in the analysis. Adjustments for fluctuations in flow in the canals were made from information obtained from water-stage recorders operated at selected locations along the canals during the time of each seepage run.

Hydrologic reconnaissance of the Fish Springs Flat area, Tooele, Juab, and Millard Counties, Utah

The Fish Springs Flat area includes about 590 square miles (1,530 square kilometers) in western Utah. Total annual precipitation on the area averages about 7 inches (180 millimeters) and totals about 232,000 acre-feet (286 cubic hectometers). Fish Springs Wash is the major drainage in the area; and, along with numerous smaller washes, it flows only in direct response to precipitation. Runoff from the area is estimated to be about 2,000 acre-feet (2.5 cubic hectometers) per year.

Water resources of the Park City area, Utah, with emphasis on ground water

The Park City area is a rapidly growing residential and recreational area about 30 miles east of Sal t Lake City (fig. 1). The area of study is about 140 square miles in which the principle industries are agriculture, skiing, and other recreational activities. The area once was a major lead- and silver-mining district, but no mines were active in 1984. A resumption in mining activity, however, could take place with an increase in the price of metals. The population of the Park City area is expected to increase rapidly in the near future; and the provision of an adequate water supply for the growing population, while avoiding harmful affects of development, is a major concern for local municipalities, developers, and the Utah Division of Water Rights. In addition, agricultural interests in and below the area are concerned about the effects of increased ground-water withdrawals on streamflow, which is fully appropriated by downstream users. The area also contains the proposed site for the Jordanelle dam, a part of the Bonneville unit of the central Utah Project. The damsite is near an historic mining area; and mining companies are concerned that if mining is resumed, the reservoir may create some additional dewatering problems in the mines.

Nature's Notebook 2011: Data & participant summary

Introduction The USA National Phenology Network The USA National Phenology Network (USA‐NPN; www.usanpn.org) seeks to engage a diverse range of citizen scientist volunteers, federal, state, and non‐governmental organizations, educators and professional research scientists to collect phenological observations of plants and animals using consistent standards and to contribute their observations to a national data repository. To guide this effort, the USA‐NPN National Coordinating Office (NCO), based in Tucson, Arizona, implemented an online monitoring program for plants and animals, Nature's Notebook , and has developed phenology monitoring protocols and an information management system, which includes the National Phenology Database (NPDb). We are developing a diversity of materials, tools, techniques, and protocols to assist decision making and education related to ecology, wildlife, human health, ecosystem services, natural resource management, biological conservation, and climate change adaptation.
