Interpretation of core and well log physical property data from drill hole UPH-3, Stephenson County, Illinois
J.J. Daniels, G.R. Olhoeft, J. H. Scott
1984, Open-File Report 82-941
Laboratory and well log physical property measurements show variations in the mineralogy with depth in UPH-3. Gamma ray values generally decrease with depth in the drill hole, corresponding to a decrease in the felsic mineral components of the granite. Correspondingly, an increase with depth in mafic minerals in the granite...
Maps showing altitude of the potentiometric surface and changes in water levels of the alluvial aquifer in eastern Arkansas, Spring 1983
Joe Edds, Daniel J. Fitzpatrick
1984, Water-Resources Investigations Report 84-4264
The Mississippi River Alluvial Aquifer is a major source of water supply for irrigation in much of eastern Arkansas. Hydrologic maps of the potentiometric surface, water-level changes and depths to water in the aquifer, based on Spring 1983 measurements, are presented. The Mississippi River Alluvial Aquifer is comprised of Quaternary...
Water-table contours, directions of ground-water movement, and measurements of inflow to American Falls Reservoir, southeastern Idaho, April 1984
H.W. Young
1984, Water-Resources Investigations Report 84-4269
In 1978 the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluating the effects of long-term development of the aquifer and to develop a capability for predicting aquifer response to alternative changes in ground-water management. By use of a...
Geohydrology of the valley-fill aquifer in the Bath area, Lower Cohocton River, Steuben County, New York
Timothy S. Pagano, D.B. Terry, M.L. Shaw, A.W. Ingram
1984, Water-Resources Investigations Report 85-4095
The Bath valley-fill aquifer, southern New York, composed of outwash, ice-contact, and ice-disintegration sand and gravel, is highly productive and is in many areas in hydraulic contact with the Cohocton River. Potential well yields range 50 to more than 1,000 gallons per minute. Most of the aquifer is under shallow...
