This report is the twelfth 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

This bibliography contains a complete listing to December 31, 1974, of reports relating to the water resources of Utah prepared by personnel of the U.S. Geological Survey. Discussions of the related subjects of geology, hydrology, and chemical quality of the water are included in many of the reports. The reports were, for the most part, prepared by personnel assigned to the Water Resources Divisio

This report summarizes the findings of an investigation of the water resources of the southern Uinta Basin conducted by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The purpose of the investigation was to evaluate the water resources of the southern Uinta Basin on a reconnaissance level and to provide information to assist in fu

Monthly, annual, and long-term mean streamflow were estimated for streams in the Duchesne River basin by use of the monthly measurement method. Monthly measurements were attempted at 44 sites in the basin during the 1971 and 1972 water years. Some measurements could not be made because some sites were not accessible at all times, some of the streams did not have flow at all times, or some of the s

County constitute the most extensive aquifers in the county. Four areally distinct sand and gravel aquifers were mapped in the drift during the course of this study. The aquifer of greatest economic importance consists of sand and gravel deposits of glacial-outwash origin which coincide with the courses of the White River and Fall Creek. Ground water in this aquifer is generally unconfined. Three

The configuration of the water table as plotted at a contour interval of 20 feet (6 metres) on quadrangle maps (scale 1:2,500) of the Minneapolis-Saint Paul metropolitan area. Control points used for mapping were water levels in wells, lakes and sloughs, and places where topographic contours cross perennial streams. A computer program, using a variation of Darcy's law, was developed to determine d

Historical inflows into Lake Chippewa for 39 years of record were analyzed to determine the possibility of operating the flowage within a 2-foot (0.6-metre) range of stage while maintaining a minimum discharge of 57 cubic feet per second (1.6 cubic metres per second) and limiting the maximum discharge to 7,000 cubic feet per second (200 cubic metres per second). This proposed operating plan could

This report presents low-flow characteristics and mean annual discharge for a site on Klawitter Creek, where an application for diversion of streamflow has been made. This information will be used by the Wisconsin Department of Natural Resources to determine the availability of irrigation water from the stream while maintaining sufficient streamflow to support fish. The study was done in cooperati

Selected physical, chemical, and biological parameters were determined to assess the quality of 20 lakes in the cities of Eagan and Apple Valley, Minn. All the lakes are eutrophic except Holland and Fish Lakes, which are mesotrophic. Some lakes (including Fish Lake) have storm sewer inlets but are not discernibly different in quality than lakes with no such inlets.

A water-quality assessment of the Burnham Creek watershed, Polk County, Minn., was made in May 1975. Surface waters were calcium magnesium bicarbonate types with 0.11 mg/liter or less of nitrite plus nitrate nitrogen and 0.10 mg/liter or less of total phosphorous. Fecal coliform bacteria concentrations were between 3 and 720 colonies per 100 milliliters and fecal Streptococci concentrations ranged

The Upper Mississippi Region in general is rich in water-surface water is plentiful, and ground water is a large, important, and manageable resource. Total potable water in storage in the outwash and alluvial aquifers of the Mississippi River valley and the subbasins is about 45,000 billion gallons. This is about 10 percent of the water in storage in Lake Ontario. Water in storage in other aquifer
