Water-quality appraisal, Mammoth Creek and Hot Creek, Mono County, California
J. G. Setmire
1984, Water-Resources Investigations Report 84-4060
A late summer reconnaissance in 1981 and a spring high-flow sampling in 1982 of Mammoth Creek and Hot Creek, located in the Mammoth crest area of the Sierra Nevada, indicated that mineralization, eutrophication, sedimentation, and limited areas of fecal contamination were occurring. Mineralization, indicated by a downstream increase in dissolved-solids...
United States earthquakes, 1973
J.L. Coffman, C. A. von Hake, William Spence, D. L. Carver, P. A. Covington, G.J. Gunthy, W.L. Irby, W. J. Person, C. W. Stover
1984, Open-File Report 84-973
National water summary 1983: Hydrologic events and issues
Water Resources Division, U.S. Geological Survey
1984, Water Supply Paper 2250
The United States as a Nation possesses abundant water resources and has developed and used those resources extensively. The national renewable supply of water is about 1,400 billion gallons per day (for the conterminous 48 States). Approximately 380 billion gallons per day of freshwater is withdrawn for use by the...
Simulated ground-water flow in the Potomac aquifers, New Castle County, Delaware
Mary Martin
1984, Water-Resources Investigations Report 84-4007
Flow in three aquifers of the Potomac Formation in New Castle County, Delaware, was simulated. Results of the calibrated flow model show the maximum transmissivity of the lower aquifer is between 1,000 and 1,500 square feet per day; the middle aquifer, between 3,000 and 3,500 square feet per day; and...
Numerical simulation of the High Plains regional aquifer, northwestern Oklahoma
J.S. Havens, S. C. Christenson
1984, Water-Resources Investigations Report 83-4269
The High Plains aquifer consists of the Tertiary Ogallala Formation and overlying Quaternary alluvium and terrace deposits together with parts of underlying rocks. Before extensive irrigation in the 1960's, recharge from precipitation was balanced by natural discharge. Baseflow was estimated as approximately 118 cubic feet per second in 1980. A...
Reconnaissance geologic map of the Noatak C5, D5, D6, and D7 quadrangles, Alaska
C.F. Mayfield, Inyo Ellersieck, I.L. Tailleur
1984, Open-File Report 84-396
This map covers the northwestern part of the Noatak 1:250,000-scale quadrangle (fig. 1, sheet 1). The area has low topographic relief that largely consists of gently sloping hills separated by broad expanses of tundra growing on unconsolidated surficial materials. Elevations range from sea level up to 475 m (1,456 ft.)...
Computer model of one-dimensional equilibrium controlled sorption processes
D.B. Grove, K.G. Stollenwerk
1984, Water-Resources Investigations Report 84-4059
A numerical solution to the one-dimensional solute-transport equation with equilibrium-controlled sorption and a first-order irreversible-rate reaction is presented. The computer code is written in FORTRAN language, with a variety of options for input and output for user ease. Sorption reactions include Langmuir, Freundlich, and ion-exchange, with or without equal valance....
Ground-water quality in Wyoming
L. R. Larson
1984, Water-Resources Investigations Report 84-4034
This report graphically summarizes ground-water quality from selected chemical-quality data for about 2,300 ground-water sites in Wyoming. Dissolved-solids, nitrate, fluoride, arsenic, barium, cadmium, chromium, lead, mercury, selenium, iron, and manganese concentrations are summarized on a statewide basis. The major chemical-quality problem that limits the use of Wyoming ground-water is excessive...
Trace metals in Suisun Bay, California: A preliminary report
S. N. Luoma, P. V. Cascos, R. M. Dagovitz
1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
Water-data program of the US Geological Survey in Kansas, fiscal year 1983
R.K. Livingston, K.D. Medina
1984, Water-Resources Investigations Report 84-4306
The U.S. Geological Survey is the principal Federal agency responsible for the collection of hydrologic data needed for the planning, development, use, and management of the water resources in Kansas. Hydrologic-data collection by the U.S. Geological Survey in Kansas began in 1895. The fiscal-year 1983 water-data program, operated in cooperation...
