Bibliographies and location maps of aeromagnetic and aeroradiometric publications for the states east of the Mississippi River and north of the Ohio and Potomac rivers
Patricia L. Hill
1986, Open-File Report 86-525-C
Bibliographies and location maps of selected publications containing aeromagnetic and/or aeroradiometric data have been compiled for each state. These state indexes have been grouped together to form seven open-file reports: four for the conterminous United States (see index map below), one for Alaska and Hawaii, one for Puerto Rico and...
Floods of June-July 1982, in Iowa
A.J. Heinitz
1986, Open-File Report 85-151
Record flood-peak discharges occurred in June and July, 1982, in southwestern, south-central, and east-central Iowa. The record flood peaks resulted from rainfalls of 6 to 8 inches on soil saturated from persistent moderate to heavy rainfalls that began in May and continued through mid July. May was the wettest across Iowa...
Hydraulic characteristics of Upper Cretaceous and Lower Tertiary clastic aquifers: Eastern Alabama, Georgia, and western South Carolina
Robert E. Faye, Keith W. McFadden
1986, Water-Resources Investigations Report 86-4210
Transmissivity and storativity data for the clastic sediments of the northern Coastal Plain of eastern Alabama, Georgia, and western South Carolina were compiled and evaluated. Transmissivity values ranged from less than 100 to about 35,000 ft sq/day; storativity ranged from about 0.00002 to 0.0002. Data for lower Tertiary sediments represented...
Hydrogeology and simulation of water flow in strata above the Bearpaw Shale and equivalents of eastern Montana and northeastern Wyoming

1986, Water-Resources Investigations Report 85-4281
The Powder River, Bull Mountains, and Williston basins of Montana and Wyoming were investigated to understand the geohydrology and subsurface water flow. Rocks were separated into: Fox Hills-lower Hell Creek aquifer (layer 1), upper Hell Creek confining layer (layer 2), Tullock aquifer (layer 3), Lebo confining layer (layer 4), and...
Assessment of low-flow water quality in the Du Page River, Illinois
W.O. Freeman, A.R. Schmidt, J. K. Stamer
1986, Water-Resources Investigations Report 85-4344
The relations of several stream processes to concentrations of dissolved oxygen and other constituents during low-flow periods were evaluated for a 70.3-mile reach of the Du Page River in northeastern Illinois, using measured data and computer simulations. Reaeration rates and traveltimes were measured at various flow rates using a steady-state...
Geohydrology of and potential for fluid disposal in the Arbuckle Aquifer in Kansas
J. E. Carr, H.E. McGovern, Tony Gogel, J.H. Doveton
1986, Open-File Report 86-491
The Arbuckle aquifer is an extensive aquifer that contains mostly saline water and that immediately overlies Precambrian ' basement ' rocks throughout Kansas, except for major uplift areas where it has been removed by erosion. In the southeast part of the state, it is a major freshwater aquifer. The upper...
Plan of study for the Regional Aquifer-System Analysis, Columbia Plateau, Washington, northern Oregon, and northwestern Idaho
J. J. Vaccaro
1986, Water-Resources Investigations Report 85-4151
The U.S. Geological Survey began a 4-year study of the regional aquifer system underlying the Columbia Plateau, in central and eastern Washington, northern Oregon, and northwestern Idaho in October 1983, as part of the Regional Aquifer System Analysis program. The study will describe the geohydrology, geochemistry, and quality of water...
Hydrogeologic sections of the Edwards Aquifer and its confining units in the San Antonio area, Texas
Ted A. Small
1986, Water-Resources Investigations Report 85-4259
Twenty-seven geohydrology sections illustrate structural and stratigraphic relationships within the 180-mi-long Edwards aquifer. These sections were used to interpret the location of barriers within the Edwards aquifer. The sections are oriented generally south-southeast, which is approximately normal to both the east-northeast trending Edwards aquifer and the strike of the major...
Selected hydrologic data for Salt Lake Valley, Utah, October 1968 to October 1985
R. L. Seiler
1986, Open-File Report 86-249
This report contains hydrologic data collected in Salt Lake Valley from October 1968 to October 1985. The report area is bounded by the Wasatch Range on the east, the Oquirrh Mountains on the west, the Traverse Mountains on the south, and the boundary between Davis and Salt Lake Counties on...
Chemical quality of ground water in Salt Lake Valley, Utah, 1969-85
K.M. Waddell, R. L. Seiler, D. K. Solomon
1986, Open-File Report 86-138
During 1979-84, 35 wells completed in the principal aquifer in the Salt Lake Valley, Utah, that had been sampled during 1962-67 were resampled to determine if water quality changes had occurred. The dissolved solids concentration of the water from 13 of the wells has increased by more than 10% since...
Ground-water levels in the alluvial aquifer in eastern Arkansas, 1985
Maria Plafcan
1986, Open-File Report 86-242
This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service and local Conservation Districts, contains groundwater level measurements in 485 wells tapping the Mississippi River Valley alluvial aquifer of eastern Arkansas. The measurements were made by district...

Application of a parameter-estimation technique to modeling the regional aquifer underlying the eastern Snake River plain, Idaho
Stephen P. Garabedian
1986, Water Supply Paper 2278
A nonlinear, least-squares regression technique for the estimation of ground-water flow model parameters was applied to the regional aquifer underlying the eastern Snake River Plain, Idaho. The technique uses a computer program to simulate two-dimensional, steady-state ground-water flow. Hydrologic data for the 1980 water year were used to calculate recharge...
