Hydrologic reconnaissance of the Dugway Valley-Government Creek area, West-Central Utah
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 in the area are insignificant.

Hydrologic reconnaissance of the Pine Valley drainage basin, Millard, Beaver, and Iron counties, Utah
The Pine Valley drainage basin is an area of about 730 square miles (1,890 square kilometres) in Millard, Beaver, and Iron Counties in southwestern Utah. Total annual precipitation in the basin averages about 410,000 acre-ft (acre-feet) or 506 hm 3 (cubic hectometres). Less than 500 acre-ft (0.6 hm 3 ) of runoff reaches the playa on the lowest part of the valley floor. There is no surface outflow from the basin. All streams are ephemeral except in short headwater reaches of a few streams where perennial or intermittent ground-water discharge sustains flow. Surface-water development and use in the basin are insignificant.

Hydrologic reconnaissance of the Wah Wah Valley drainage basin, Millard and Beaver Counties, Utah
The Wah Wah Valley drainage basin is an area of about 600 square miles (1,550 km 2 ) in Millard and Beaver Counties in southwestern Utah. Surface-water supplies of the area are negligible--total runoff averages about 7,800 acre-feet (9.62 hm 3 ) annually, all streams are ephemeral or intermittent, and surface storage is negligible. Evaporation and transpiration within the basin consume more than 97 percent of total annual precipitation. There is no surface outflow.
Hydrologic reconnaissance of the northern Great Salt Lake Desert and summary hydrologic reconnaissance of northwestern Utah
This report is the thirteenth in a series prepared by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, that describes the water resources of selected basins in western Utah. The purpose of this series of reconnaissances is to analyze available hydrologic data, to evaluate present and potential water-resource development, and to identify additional studies that might be needed in the future to provide a fuller understanding of the hydrologic system.
Developing a state water plan: Ground-water conditions in Utah, spring of 1974
This report is the eleventh 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 such as legislators, administrators, and planners to keep abreast of changing ground-water conditions. This report, like the others (see references, p. 18), contains information on well construction, ground-water withdrawals, water-level changes, and related changes in precipitation and streamflow. Supplementary data such as graphs showing chemical quality of water and maps showing water-table configuration are included in reports of this series only for those years or areas for which applicable data are available and are important to a discussion of changing ground-water conditions. The report includes individual discussions of the most important areas of ground-water withdrawal in the State for the calendar year 1973. Water-level fluctuations, however, are described for the period spring 1973 to spring 1974. Many of the data used in the report were collected by the Geological Survey in cooperation with the Division of Water Rights, Utah Department of Natural Resources.
Hydrologic reconnaissance of Pilot Valley, Utah and Nevada
This report, prepared by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, is the twelfth in a series of reports that describe the water resources of the western basins of Utah. (See fig. 1.) Its purpose is to present available hydrologic data on the Pilot Valley area, to provide an evaluation of the potential for water-resource development in the area, and to identify studies that would improve understanding of the area's water supply.
