The potentiometric surface of water in the Upper Cretaceous Fox Hills-lower Hell Creek aquifer is shown on a base map at a scale of 1:1,000,000. The map is one of a series produced as part of regional study of aquifers of Cenozoic and Mesozoic age in the northern Great Plains...

The potentiometric surface of water in the Upper Cretaceous Eagle Sandstone and equivalent units (Virgelle Sandstone and Telegraph Creek Formation) is shown on a base map at a scale of 1:1,000,000. The map is one of a series of maps produced as part of a regional study of aquifers of...

More than 2,000 water-level measurements made in Georgia in 1981 provide the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year (1980) and fluctuations of the monthly mean water levels are shown for selected years in some observation wells in...

The southeastern Uinta Basin in Utah and Colorado contains large reserves of oil shale, the mining of which could affect the area 's water resources. Climatic characteristics of the area, which were evaluated as one phase of a comprehensive hydrologic study, are presented to help provide the means of evaluating...

An aquifer test conducted in the Green Swamp area December 15-16 , 1975 was designed to stress the uppermost part of the Floridan aquifer so that the leakage characteristics of the overlying confining bed could be determined. A well tapping the upper part of the Floridan aquifer was pumped at...

A September 1982 potentiometric surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Water levels in most wells measured in September 1982 were higher than in May 1982. Levels averaged about 12 feet higher in the southern part of the area and about 5...

The U.S. Geological Survey has tested a borehole-configured heat-pulse flowmeter which has good low-velocity flow-measuring sensitivity. The flowmeter was tested in the laboratory in 51-, 102-, and 152-millimeter-diameter columns using water velocities ranging from 0.35 to 250 millimeters per second. The heat-pulse flowmeter also was tested in a 15-meter-deep granite...

Statistical analyses of precipitation data from a nine-station monitoring network indicate little change in pH from 1965-78 within New York State as a whole but suggest that pH of bulk precipitation has decreased in the western part of the State by approximately 0.2 pH units since 1965 and increased in...

The Green River-Moab area encompasses about 7,800 square kilometers or about 25 percent of the Paradox basin. The entire Paradox basin is a part of the Colorado Plateaus that is underlain by a thick sequence of evaporite (salt) beds of Pennsylvanian age. The rock units that underlie the area have...

Water resources data for the 1981 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of wells. This report contains discharge records for 66 gaging stations; stage only for 2 gaging...

Water resources data for the 1980 water year for Arizona consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; water levels of observation wells; and quality of ground water. This report contains discharge records for 240 gaging stations, annual...

During the 13-year period, February 1962 to February 1975, about 540,000 acre-feet of ground water was pumped from Pahrump Valley. This resulted in significant water-level declines along the base of the Pahrump and Manse fans where pumping was concentrated. Maximum observed net decline was slightly more than 60 feet. Much...

In a preliminary survey, Crassostrea virginica from areas of the Corpus Christi Bay system of Texas show significant concentrations of Cd, Cu, Pb, and Zn in their tissues and shells; concentrations of these same metals in associated sediments are also high in certain areas of the bay system. Zn and...

The Salmon River basin drains approximately 13,000 square miles in central Idaho underlain by the Idaho batholith. Geologic units in the basin include igneous, sedimentary, and metamorphic rocks and granitic rocks predominate. Water from thermal springs ranges in temperature from 20.5 degrees to 94.0 degrees Celsius. The waters are slightly...

This report presents hydrologic investigations and data collections conducted by the U.S. Geological Survey in the strippable coal areas of northwestern New Mexico. Streamflow, ground-water, and quality-of-water data were collected to provide information about baseline or prevailing hydrologic conditions. A network of hydrologic data-collection sites in the strippable coal areas...

Water resources data for the 1981 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 178 gaging stations; stage only...

Assessment of surface-mining and reclamation activities generally requires extensive hydrologic data. Adequate streamflow data from instrumented gaging stations rarely are available, and estimates of surface- water discharge based on rainfall-runoff models, drainage area, and basin characteristics sometimes have proven unreliable. Channel-geometry measurements offer an alternative method of quickly and inexpensively...
