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...
Determination of pentachlorophenol in water and aquifer sediments by high-performance liquid chromatography
D.F. Goerlitz
1981, Open-File Report 82-124
Methods for the determination of pentachlorophenol (PCP) in water and aquifer sediments are presented. Reverse-phase high-performance liquid chromotography employing ion suppression and gradient elution is used. PCP can be determined directly in water at a lower limit of detection Of 0.2 micrograms per liter. For extracts of sediment, PCP can...
Floods of September 16, 1975 in the Tallaboa Valley, Puerto Rico
Karl G. Johnson
1981, Open-File Report 80-1283
This report provides a record of the flood of September 16, 1975, and associated hydrologic data. These data can be used in making rational decisions in formulating effective flood-plain regulations that would minimize flood problems in the Tallaboa Valley.The Tallaboa Valley (fig. 1) lies on the southwestern coast of Puerto...
Selected drill-stem-test data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...
Selected hydrogeologic data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-534
Selected hydrologic data have been used in a 4-year study of aquifers of Cenozoic and Mesozoic age in the northern Great Plains to define the hydrologic system and to generate hydrologic maps. Records of 6,754 wells and 188 springs are tabulated in the report. The well data include site location,...
Hydraulic analysis, Paint Creek at State Route 772, Chillicothe, Ohio
R.I. Mayo, W.P. Bartlett Jr.
1981, Open-File Report 81-350
The Ohio Department of Transportation, Division of Highways, proposes to replace a three-span arch, bridge across Paint Creek on South Paint Street in Chillicothe, Ohio with a new deck-type structure resting on four sets of piles and four piers. Profiles of the 10-, 25-, 50- and 100-year floods under present...
Hydrology and the effects of industrial pumping in the Nikiski area, Alaska
Gordon L. Nelson
1981, Open-File Report 81-685
Ground-water consumption for industrial use at Nikiski increased from about 1 million gallons per day in 1968 to 4.2 million gallons per day in 1979. Water managers and local citizens are concerned that industrial pumping may reduce the esthetic and recreational value of local lakes. Some lake levels have declined...
Road log and documentary photographs for 15 significant biostratigraphic sites in Miocene-Pliocene limestone, Kingshill Seaway, St. Croix, U.S. Virgin Islands
Barbara H. Lidz
1981, Open-File Report 81-1291
Detailed examination of planktonic Foraminifera from the type section of the Miocene Kingshill Limestone and from 14 other Miocene and lower Pliocene limestone exposures in the Kingshill Seaway of St. Croix ((at 17°44' N., long 64° 46' W.; fig. 1) has led to the first publication of an in-depth biostratigraphic...
Magnitude and chemical quality of base flow of Otter Creek, Tongue River, and Rosebud Creek, southeastern Montana, October 26-November 5, 1977
Roger W. Lee, Steven E. Slagle, James R. Stimson
1981, Open-File Report 80-1298
Hydrologic and chemical data were collected during base-flow conditions on three streams in southeastern Montana from October 26 to November 5, 1977, to characterize groundwater discharge. Maximum measured flow of Otter Creek, an interrupted stream, was 1.2 cubic feet per second. The water chemistry was dominated by sodium, magnesium, and...
Hydrologic monitoring in the coal fields of central Utah, August 1978-September 1979
Gregory C. Lines, Gerald G. Plantz
1981, Open-File Report 81-138
Surface-water quantity and quality were observed at 12 gaging stations downstream from mined and lease areas in the Wasatch Plateau, Book Cliff's, and Emery coal fields in central Utah. Measurements of base flow were made at 52 additional sites in the region. The report describes the hydrologic setting of this...
A 10-year plan to study the aquifer system of Indian Wells Valley, California
Paul Lipinski, Darwin D. Knochenmus
1981, Open-File Report 81-404
Water needs of the population of Indian Wells Valley, Calif., must be met through further development of ground-water resources. Studies show that annual ground-water pumpage there has increased since 1945 and has exceeded mean annual recharge since 1966. Continued and increased stress on the aquifer system of the valley is...
Low flow of streams in Fairfax County, Virginia
E. H. Mohler, G. F. Hagan
1981, Open-File Report 81-63
The effect of geologic differences and urban development on low-flow characteristics of streams in Fairfax County, Va., are discussed. Tables of annual minimum 7-day average flow values for various recurrence intervals are presented for 5 long-term gaging stations and for 37 selected low-flow measurement sites. Drainage-basin boundaries and 7-day 10-year...
Hydrologic conditions at the Idaho National Engineering Laboratory, Idaho, emphasis: 1974-1978
Jack T. Barraclough, Barney D. Lewis, Rodger G. Jensen
1981, Open-File Report 81-526
The Idaho National Engineering Laboratory (INEL) site covers about 890 square miles of the eastern Snake River Plain and overlies the Snake River Plain aquifer. Low concentrations of aqueous chemical and radio-active wastes have been discharged to shallow ponds and to shallow or deep wells on the site since 1952....
