Water resources data, Maine, water year 1986
W.P. Bartlett Jr., W.B. Higgins, W.J. Nichols Jr.
1988, Water Data Report ME-86-1
Water resources data for the 1986 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains discharge records for 48 gaging stations; stage only for 2...
Hydrology of Alkali Creek and Castle Valley Ridge coal-lease tracts, central Utah, and potential effects of coal mining
R. L. Seiler, R. L. Baskin
1988, Water-Resources Investigations Report 87-4186
The Alkali Creek coal-lease tract includes about 2,150 acres in the Book Cliffs coal field in central Utah, and the Castle Valley Ridge coal-lease tract includes about 3,360 acres in the Wasatch Plateau coal field, also in central Utah. Both the Alkali Creek and Castle Valley Ridge coal-lease tracts are...
Hydrogeology and preliminary assessment of regional flow in the upper Cretaceous and adjacent aquifers in the northern Mississippi embayment
J. V. Brahana, T. O. Mesko
1988, Water-Resources Investigations Report 87-4000
On a regional scale, the groundwater system of the northern Mississippi embayment is composed of a series of nonindurated clastic sediments that overlie a thick sequence of Paleozoic carbonate, sandstones, and shales. The units that comprise the geohydrologic framework of this study are the alluvium-lower Wilcox Aquifer the Midway confining...
Basic hydraulic principles of open-channel flow
Harvey E. Jobson, David C. Froehlich
1988, Open-File Report 88-707
The three basic principles of open-channel-flow analysis--the conservation of mass, energy, and momentum--are derived, explained, and applied to solve problems of open-channel flow. These principles are introduced at a level that can be comprehended by a person with an understanding of the principles of physics and mechanics equivalent to that...
Climatic data for Williams Lake, Hubbard County, Minnesota, 1982
D.O. Rosenberry, A.M. Sturrock, J.L. Scarborough, T. C. Winter
1988, Open-File Report 88-89
Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Those climatic data needed for energy budget and mass transfer studies are presented , including: water surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these...
Operating manual for the R200 downhole recorder with husky hunter retriever
Roy A. Johnson, James I. Rorabaugh
1988, Open-File Report 88-455
The R200 Downhole Recorder is a battery-powered device that, when placed in a well casing, monitors water levels for a period of up to 1 year. This instrument measures a 1- to 70-foot range of water levels. These water-level data can be retrieved through use of a commercially available portable...
Streamflows in Wyoming
H. W. Lowham
1988, Water-Resources Investigations Report 88-4045
A description of the occurrence and availability of surface waters in Wyoming is presented along with explanations of both streamflow-data collection and methods for estimating streamflow characteristics at gaged and ungaged sites. Mountain ranges separate the major drainage basins and have a significant effect on the quantity of precipitation and...
Methods for collection and analysis of aquatic biological and microbiological samples
L. J. Britton, P. E. Greeson
1988, Open-File Report 88-190
Chapter A4, methods for collection and analyses of aquatic biological and microbiological samples, contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. Part 1 consists of detailed descriptions of more than 45 individual methods, including those for bacteria,...
Results of qualification tests on water-level sensing instruments, 1986
Randolph R. Holland, Donald H. Rapp
1988, Open-File Report 88-193
This report presents to users of hydrological instrumentation and U.S. Geological Survey procurement personnel a list of instruments that have met or exceeded the Survey 's minimum performance requirements for water level sensing instruments. The Hydrologic Instrumentation Facility at the National Space Technology Laboratories, Mississippi conducted qualification tests on four...
Hydrology of the chain of lakes tributary to Devils Lake and water-level simulations of Devils Lake, northeastern North Dakota
Gerald L. Ryan, Gregg J. Wiche
1988, Water-Resources Investigations Report 88-4020
High water levels of the chain of lakes tributary to Devils Lake, North Dakota have, in recent years, caused flooding of cropland and county roads, thus disrupting agricultural interests. High water levels of Devils Lake pose a flood threat to the city of Devils Lake, Camp Grafton National Guard Camp,...
Application of the two-film model to the volatilization of acetone and t-butyl alcohol from water as a function of temperature
R. E. Rathbun, D. Y. Tai
1988, Water Supply Paper 2318
The two-film model is often used to describe the volatilization of organic substances from water. This model assumes uniformly mixed water and air phases separated by thin films of water and air in which mass transfer is by molecular diffusion. Mass-transfer coefficients for the films, commonly called film coefficients, are...
Water resources of the Apostle Islands National Lakeshore, northern Wisconsin
W. J. Rose
1988, Water-Resources Investigations Report 87-4220
The Apostle Islands National Lakeshore consists of 21 islands, part of the Bayfield Peninsula, and the adjacent waters of Lake Superior. Selected water resources of the Apostle Islands National Lakeshore were assessed to aid the National Park Service in developing and managing the Lakeshore and to provide a data base...
Potential flood and debris hazards at Katherine Landing and Telephone Cove, Lake Mead National Recreation Area, Mohave County, Arizona
Otto Moosburner
1988, Water-Resources Investigations Report 87-4081
Katherine Landing is a recreation site on the east shore of Lake Mohave, an impoundment on the Colorado River southeast of Las Vegas, Nevada. With proper inspection and maintenance, the present (1979) channel and diking system at Katherine Landing is judged adequate to confine and restrain floods up to and...
