Map of water table in Graham County, northwestern Kansas, March 1979
Joseph M. Spinazola
1981, Open-File Report 81-333
A map of the water table in Graham County, prepared in collaboration with the U.S. Bureau of Reclamation, provides current (1980) information on water levels in the unconsolidated deposits. Graham County, an area of 900 square miles in northwestern Kansas, is within the rolling, moderately to well-dissected terrain on the...
Stream-temperature patterns of the Muddy Creek basin, Anne Arundel County, Maryland
E.J. Pluhowski
1981, Water-Resources Investigations Report 81-18
Using a water-balance equation based on a 4.25-year gaging-station record on North Fork Muddy Creek, the following mean annual values were obtained for the Muddy Creek basin: precipitation, 49.0 inches; evapotranspiration, 28.0 inches; runoff, 18.5 inches; and underflow, 2.5 inches. Average freshwater outflow from the Muddy Creek basin to the...
Map showing how the potentiometric surface of the Magothy Aquifer of September 1979 differed from the potentiometric surface of September 1977 in southern Maryland
Frederick K. Mack, J. C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-632
This map is based on the differences between two sets of water-level measurements made in 63 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1979, a relatively wet year. The map shows that the potentiometric surface in 1979, in...
Hydrogeology of the Buffalo aquifer, Clay and Wilkin Counties, West-Central Minnesota
R. J. Wolf
1981, Water-Resources Investigations Report 81-4
The Buffalo aquifer is the principal source of ground-water supplies in the Moorhead, Minnesota area. The aquifer is an elongate deposit of sand and gravel, which locally contains water under confined conditions. Although the Buffalo aquifer contains about 270 billion gallons of water in storage, only 120 billion gallons could...
Modeled impacts of surface coal mining on dissolved solids in the Tongue River, southeastern Montana
Paul F. Woods
1981, Water-Resources Investigations Report 81-64
A computer model has been developed for spatial and temporal simulation of streamflow and dissolved solids in the Tongue River from the Tongue River Dam to Miles City, Montana. User-defined plans of surface coal mining and agricultural development permit evaluation of potential changes in dissolved solids resulting from leaching of...
