Generalized thickness and configuration of the top of the intermediate aquifer, west-central Florida
Miguel A. Corral Jr., Richard M. Wolansky
1984, Water-Resources Investigations Report 84-4018
Generalized map show the thickness and top of the intermediate aquifer in west-central Florida within the boundaries of the Southwest Florida Water Management District. The intermediate aquifer consists of a series of water-bearing units and confining beds between the surficial aquifer (water table) and the Floridan aquifer. This aquifer contains...
Water-level maps of the alluvial aquifer, Northwestern Mississippi, April 1983
David M. Sumner
1984, Water-Resources Investigations Report 83-4285
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during April 1983. Ground-water levels have declined in some areas in recent years as a result of heavy irrigation pumpage from this aquifer. Near the areas of principal recharge, along the major...
Depth and thickness of selected units in Upper Permian, Upper Jurassic, and Lower Cretaceous rocks in southwestern Kansas
Jack Kume, Joseph M. Spinazola
1984, Water-Resources Investigations Report 83-4095
As ground-water reserves decline in the Ogallala aquifer in an area of about 17,400 square miles in 26 counties of southwestern Kansas, sandstone aquifers in underlying Upper Jurassic and Lower and Upper Cretaceous rocks may be developed to supplement or replace the Ogallala as a source of water for some...
Hydrogeology of the Sulphur Springs area, Tampa, Florida
J. W. Stewart, L. R. Mills
1984, Water-Resources Investigations Report 83-4085
The Sulfur Springs area includes about 56 square miles in west-central Hillsborough County, Florida. The north-central part of the city of Tampa is highly urbanized; the north-west part of the area is rural or undeveloped. The area has numerous sinkholes, two of which are used as retention basins for urban...
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...
Drainage basins in St. Johns County, Florida
Donald W. Foose
1984, Water-Resources Investigations Report 84-4232
The highest point in St. Johns County, Florida is only slightly above 65 feet above sea level and drainage divides are indistinct and readily influenced by cultural features. This report delineates some 80 drainage basins (or artificial equivalents to natural basins such as the Intracoastal Waterway) within the county and...
Hydrologic maps of the Price 30 x 60-minute quadrangle, Utah
H.F. McCormack, K.L. Lindskov, Bernard J. Stolp
1984, Water-Resources Investigations Report 84-4227
Four hydrologic maps of the Price 30 x 60-minute quadrangle, Utah show that the hydrology of the area is extremely variable. Normal annual precipitation ranges from less than 8 to more than 25 inches. Corresponding ranges are less than 0.1 to more than 5 inches for average annual runoff, 0.1...
