Drainage divides, Massachusetts; Blackstone and Thames River basins
Bruce E. Krejmas, S. William Wandle
1982, Open-File Report 82-631
Drainage boundaries for selected subbasins of the Blackstone and Thames River basins in eastern Hampden, eastern Hampshire, western Norfolk, southern Middlesex, and southern Worcester Counties, Massachusetts, are delineated on 12 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and...
Geohydrology of the preglacial Genesee Valley, Monroe County, New York
Roger Milton Waller, T. J. Holecek, W.B. Stelz, J. L. Belli
1982, Open-File Report 82-552
This report is last in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on five maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a buried glacio-fluvial aquifer in Monroe County. The maps include surficial...
Hydrogeologic and water-quality characteristics of the Ironton-Galesville aquifer, southeast Minnesota
J. F. Ruhl, R. J. Wolf, D. G. Adolphson
1982, Water-Resources Investigations Report 82-4080
Quality of water in the Ironton-Galesville aquifer is generally acceptable for all kinds of uses. Calcium magnesium bicarbonate type water is most common. The dissolved-solids concentration ranges from about 200 to 1,000 milligrams per liter. The lowest values are in the northern part of the aquifer, where the bedrock is...
Geohydrology of the valley-fill aquifer in the Sprout and Fishkill creeks area, Dutchess County, New York
Richard B. Moore, R.G. LaFleur, W. G. Stelz, J. L. Belli
1982, Open-File Report 82-81
This report is the fifth in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on six maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a major valley-fill aquifer in southwestern Dutchess County and a...
Geohydrology of the valley-fill aquifer in the South Fallsburgh-Woodbourne area, Sullivan County, New York
H. R. Anderson, R. J. Dineen, W. G. Stelz, J. L. Belli
1982, Open-File Report 82-112
This report is the ninth in a series of map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on six maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a major valley-fill aquifer in southeastern Sullivan County. The maps include...
Map showing how the potentiometric surface of the Magothy Aquifer of August 1980 differed from the potentiometric surface of September 1977, in southern Maryland
Frederick K. Mack Jr., J. C. Wheeler, Stephen E. Curtin
1982, Open-File Report 81-631
The map is based on the differences between two sets of water-level measurements made in 65 observation wells. One set was made in 1977, a relatively dry year, and the other set was made in 1980, another relatively dry year. The map shows that the potentiometric surface was higher in...
Hydrologic maps of Ogallala Aquifer, west-central Kansas, 1979-81
Joseph M. Spinazola
1982, Open-File Report 82-258
A mathematical technique, called kriging, was programmed for a computer to interpolate hydrologic data based on a network of measured values in west-central Kansas. The computer program generated estimated values at the center of each 1-mile section in the Western Kansas Groundwater Management District No. 1 and facilitated contouring of...
Water-level maps of the alluvial aquifer, northwestern Mississippi April 1982
Daphne Darden
1982, Water-Resources Investigations Report 82-4061
Water levels were measured in about 500 wells in the Mississippi River valley alluvial aquifer in northwestern Mississippi during the period April 12-23, 1982. The water-level change from April 1981 to April 1982, showed a general decline, but the water-level change from September 1981 to April 1982 showed some recovery....
Map showing the difference between the potentiometric surfaces of the Magothy Aquifer of September 1975 and September 1982 in southern Maryland
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1982, Water-Resources Investigations Report 83-4283
A map was prepared that shows the net change in the potentiometric surface of the Magothy aquifer in southern Maryland from September 1975 to September 1982. The map is based on measurements from a network of 55 observation wells. During the 8-year period, the potentiometric surface was (1) lowered by...
Drainage divides, Massachusetts; Deerfield and Millers River basins
Bruce E. Krejmas, S. William Wandle Jr.
1982, Open-File Report 82-632
Drainage boundaries for selected subbasins in Franklin and northwestern Worcester Counties, Massachusetts, are delineated on 16 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and for mouths of major rivers. Drainage basins are shown for the outlets of lakes...
