Water resources data for Georgia, water year 1980
Water Resources Division, U.S. Geological Survey
1980, Water Data Report GA-80-1
Water resources data for the 1980 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 105 gaging stations; stage for 9 gaging stations; stage and contents for 17...
Water resources data for Arizona, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report AZ-79-1
Water resources data for the 1978 water year for Arizona consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; measurements of ground-water levels; and quality of water from selected wells. Also included are discharge data for crest-stage partial-record stations...
Water-quality assessment of the Cypress Creek watershed, Warrick County, Indiana
Linda L. Bobo, Charles A. Peters
1980, Water-Resources Investigations Report 80-35
The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets...
Geochemistry of fluoride in the Black Creek aquifer system of Horry and Georgetown Counties, South Carolina — And its physiological implications
Allen L. Zack
1980, Water Supply Paper 2067
High concentrations of fluoride in ground-water supplies in certain areas of Horry and Georgetown Counties, S.C., have been the cause of dental fluorosis (tooth mottling) among persons who have lived in these areas and have ingested the water as children. Geochemical evidence and laboratory experiments demonstrate that fluorapatite in the...
Effects of urban runoff and wastewater effluent on Wilsons Creek and James River near Springfield, Missouri
Wayne R. Berkas
1980, Water-Resources Investigations Report 80-27
Statistical analysis on water-quality parameters from James River upstream and downstream from the confluence of Wilsons Creek shows a significant difference for all parameters except temperature and dissolved silica at the 0.05 probability level. Regression analysis shows correlation for discharge with dissolved sodium, dissolved chloride, and dissolved potassium, and for...
Ground-water hydrology of the Sagebrush Flat area as related to the discharge of Rattlesnake Springs, Grant and Douglas counties, Washington
K.L. Walters
1980, Open-File Report 79-1530
In 1978, the U.S. Geological Survey, in cooperation with the State of Washington Department of Ecology, investigated the hydrology of the Sagebrush Flat area as it relates to Rattlesnake Springs. Rattlesnake Springs and all known wells on Sagebrush Flat obtain water from basalt aquifers. The wells tap aquifers at or...
Water-resources investigations of the U.S. Geological Survey in Colorado; fiscal year 1980
Stephen R. Blakely
1980, Open-File Report 80-442
Water-resources data-collection activities for October 1, 1979, through September 30, 1980, are summarized for Colorado and bordering States. Fifty-four interpretive hydrologic investigations include: 9 statewide investigations, 6 regional investigations, 11 investigations in the Missouri River basin, 7 investigations in the Arkansas River basin, 3 investigations in the Rio Grande basin,...
Calibration and testing of selected portable flowmeters for use on large irrigation systems
Richard R. Luckey, Frederick J. Heimes, Neville G. Gaggiani
1980, Water-Resources Investigations Report 80-72
Existing methods for measuring discharge of irrigation systems in the High Plains region are not suitable to provide the pumpage data required by the High Plains Regional Aquifer System Analysis. Three portable flowmeters that might be suitable for obtaining fast and accurate discharge measure-ments on large irrigation systems were tested...
Water-quality monitoring of three major tributaries to the Chesapeake Bay: Interim data report
David J. Lang, David Grason
1980, Water-Resources Investigations Report 80-78
The U.S. Geological Survey is monitoring the water quality of three major tributaries to Chesapeake Bay at their fall lines to obtain estimates of constituent inputs potentially available to the bay. The monitoring sites are: Susquehanna River at Conowingo, Md.; Potomac River at Washington, D.C.; and James River at Cartersville,...
Three-dimensional digital-computer model of the Ferron sandstone aquifer near Emery, Utah
Daniel J. Morrissey, Gregory C. Lines, Scott D. Bartholoma
1980, Water-Resources Investigations Report 80-62
A three-dimensional finite-difference computer model of the Ferron sand-stone aquifer was used to simulate ground-water flow in the Emery coal field in east-central Utah. The model also was used to predict the effects of pro-posed surface mining and the resulting mine dewatering on potentiometric sur-faces of the aquifer. The model...
Data-base system for northern Midwest regional aquifer-system analysis
A.L. Kontis, Richard J. Mandle
1980, Water-Resources Investigations Report 80-104
The U.S. Geological Survey is conducting a study of the Cambrian and Ordovician aquifer system of the northern Midwest as part of a national series of Regional Aquifer-Systems Analysis (RASA). An integral part of this study will be a simulation of the ground-water flow regime using the Geological Survey's three-dimensional...
Investigation of artificial recharge of aquifers in Nebraska
William F. Lichtler, David I. Stannard, Edwin Kouma
1980, Water-Resources Investigations Report 80-93
Large withdrawals of ground water for irrigation are causing progressive declines of ground-water levels in some areas of Nebraska. An investigation was conducted to determine the technical feasibility of artificially recharging aquifers through wells and through surface spreading by means of impoundments, pits, and canals. Information gained from a literature...
