National water-information clearinghouse activities; ground-water perspective
C.A. Haupt, R.A. Jensen
1988, Open-File Report 88-114
The US Geological Survey (USGS) has functioned for many years as an informal clearinghouse for water resources information, enabling users to access groundwater information effectively. Water resources clearinghouse activities of the USGS are conducted through several separate computerized water information programs that are involved in the collection, storage, retrieval, and...
Hydrologic and suspended-sediment data for Reelfoot Lake, Obion and Lake Counties, northwestern Tennessee, May 1985-September 1986

1988, Open-File Report 88-170
Hydrologic data for Reelfoot Lake in Obion and Lake Counties, Tennessee, were collected at 4 surface water inflow stations, 1 outflow station, 2 rainfall stations, 2 lake elevation stations, and 29 wells for the period May 1, 1985 through September 30, 1986. Additionally, suspended-sediment data were collected at three stations...
Metal biogeochemistry in surface-water systems; a review of principles and concepts
John F. Elder
1988, Circular 1013
Metals are ubiquitous in natural surface-water systems, both as dissolved constituents and as particulate constituents. Although concentrations of many metals are generally very low (hence the common term 'trace metals'), their effects on the water quality and the biota of surfacewater systems are likely to be substantial. Biogeochemical partitioning of...
Chemical and hydrologic data for selected thermal-water wells and nonthermal springs in the Boise Area, southwesten Idaho
H.W. Young, D. J. Parliman, Robert H. Mariner
1988, Open-File Report 88-471
Data were collected during January to July 1988 from 37 thermal-water wells and 3 nonthermal springs in the Boise area, southwestern Idaho. Included are well and spring locations; well-construction, water-level, and water-use information; hydrographs of water levels in 3 wells; chemical and isotopic analyses of water from 18 thermal-water wells...
Sources of water-use data in Minnesota
L. C. Trotta
1988, Open-File Report 87-544
Since the 1976-77 drought in Minnesota, legislators, planners, and citizens have become aware of the need for water management based on knowledge of water availability and use in order to alleviate local water shortages. In addition to maintaining an adequate supply, information on the amount of water used, where it...
Inventory of interbasin water transfers in Minnesota
L. C. Trotta
1988, Open-File Report 88-466
Water transfer data were collected by the U.S. Geological Survey , in cooperation with the Minnesota Department of Natural Resources, from the 13 hydrologic subregions in Minnesota. About 30,000 acre-ft of water is exported annually from eight of these subregions. Interbasin transfer of water is classified according to type of...
Aggregation of Minnesota water-use data and transfer of data to the National Water-Use Data System; Procedures and programs
L. C. Trotta
1988, Open-File Report 87-40
The Minnesota Water-Use Data System stores data on the quantity of withdrawals and discharge in Minnesota. To transfer these data into the U.S. Geological Survey 's National Water-Use Data System properly, certain procedures must be followed. Uniform data categorization and entry allows comparison of water use from State to State....
Climatic data for Williams Lake, Hubbard County, Minnesota, 1986
D.O. Rosenberry, A.M. Sturrock, T. C. Winter
1988, Open-File Report 88-304
Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, 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 studies, such as...
Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland
James M. Gerhart, George J. Lazorchick
1988, Water Supply Paper 2284
Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day,...
Annual yield and selected hydrologic data for the Arkansas River Basin compact, Arkansas-Oklahoma, 1987 water year
M. A. Moore, T.E. Lamb, L.D. Hauth
1988, Open-File Report 88-301
The computed annual yield and deficiency of the subbasins are defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, and mean discharges are shown for...
Bottom sediments and nutrients in the tidal Potomac system, Maryland and Virginia
Jerry L. Glenn
1988, Water Supply Paper 2234-F
The characteristics and distributions of near-surface bottom sediments and of nutrients in the sediments provide information on modern sediment and nutrient sources, sedimentation environments, and geochemical reactions in the tidal Potomac system, Maryland and Virginia. This information is fundamental to an improved understanding of sedimentation and eutrophication problems in the...
