Discharge ratings for control gates at Mississippi River Lock and Dam 11, Dubuque, Iowa
A.J. Heinitz
1985, Water-Resources Investigations Report 85-4105
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at locks and dams. Discharge ratings for the gates on Lock and Dam 11, Dubuque, Iowa, were developed from current-meter discharge measurements made in the forebays. Methodology is given...
Cost-effectiveness of the U.S. Geological Survey's stream-gaging programs in Massachusetts and Rhode Island
R. A. Gadoury, J.A. Smath, R. A. Fontaine
1985, Water-Resources Investigations Report 84-4097
The report documents the results of a study of the cost-effectiveness of the U.S. Geological Survey 's continuous-record stream-gaging programs in Massachusetts and Rhode Island. Data uses and funding sources were identified for 91 gaging stations being operated in Massachusetts are being operated to provide data for two special purpose...
Water resources data, West Virginia, water year 1984
W.N. Embree, E.A. Friel, F.M. Taylor
1985, Water Data Report WV-84-1
Water resources data for the 1984 water year for West Virginia consist of records of stage, discharge, and water quality of streams and springs, and water levels of ground water. This report contains discharge records for 76 gaging stations; stage only records for 13 gaging stations; contents fon 2 reservoirs;...
Simulated effects of projected pumping on the availability of freshwater in the Evangeline Aquifer in an area southwest of Corpus Christi, Texas
George E. Groschen
1985, Water-Resources Investigations Report 85-4182
This study is an investigation of the continued availability of freshwater in the Evangeline aquifer along the Texas Gulf Coast and the potential for degradation of the water quality by salinewater intrusion. Recharge to the aquifer occurs by the infiltration of precipitation in the outcrop area and by cross-formational flow...
Regional geochemical study of the felsic plutonic rocks in the Nuqrah Quadrangle, sheet 25E, Kingdom of Saudi Arabia
W. E. Hall, David Dellinger, G.I. Selner
1985, Open-File Report 85-25
A regional geochemical investigation of the felsic plutonic rocks of the Nuqrah quadrangle, sheet 25 E, Kingdom of Saudi Arabia, in which pan concentrates of 384 wadi samples, and 145 rock samples, were collected, defined two separate and distinct anomalous areas. One area contains Jabal Tuwalah and Jabal Awja, and...
Potentiometric surfaces of the coastal plain aquifers of South Carolina prior to development
Walter R. Aucott, Gary K. Speiran
1985, Water-Resources Investigations Report 84-4208
Characteristics of the Coastal Plains aquifers of South Carolina are being studied as a part of the Regional Aquifer Systems Analysis program of the U.S. Geological Survey. A framework has been developed to best represent the hydrology of the Coastal Plain aquifers by dividing them into a system of five...
Chemical quality of ground water in Yolo and Solano counties, California
K. D. Evenson
1985, Water-Resources Investigations Report 84-4244
Ground-water-quality conditions were investigated in Yolo and Solano Counties during the summers of 1980 and 1981 by sampling 188 representative wells. Chemical analyses of the water samples show that the ground water is suitable for domestic and most agricultural purposes. Water samples from wells near the Sacramento River generally contained...
Occurrence of ground water and potential for seawater intrusion, Island County, Washington
M. A. Jones
1985, Water-Resources Investigations Report 85-4046
The data from a study of groundwater availability and quality in Island County, Washington, are presented. Increased groundwater withdrawals associated with the population increase in Island County have caused concern about groundwater availability and potential seawater intrusion. The most widely used aquifer lies near sea level. Locally, available data indicate...
Potentiometric surface of the upper Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1985
George R. Schiner, Eugene C. Hayes
1985, Open-File Report 85-644
This map shows the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity for September 1985. The Upper Floridan aquifer is the principal source of potable water in the area. Water level measurements were made on approximately 1,000 wells and on several...
