Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1990-91
Ronald G. Garrett
1992, Open-File Report 92-110
Water quality measurements were made at six sites in or near North Carolina's Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations. In the...
Evaluation of the use of remote-sensing data to identify crop types and estimate irrigated acreage, Uvalde and Medina counties, Texas, 1989
L.H. Raymond, G.M. Nalley, P.L. Rettman
1992, Water-Resources Investigations Report 92-4117
Remote-sensing data were used to estimate that 190,000 acre-feet of water was pumped from the Edwards aquifer in 1989 to irrigate crops in Uvalde and Medina Counties. Landsat digital satellite images for March and July 1989 were combined and classified to identify the areas of crops irrigated with water from...
Water, Energy, and Biogeochemical Budgets (WEBB) program: Data availability and research at the Northern Temperate Lakes site in north-central Wisconsin
John F. Elder, David P. Krabbenhoft, John F. Walker
1992, Open-File Report 92-48
More than three thousand kettle lakes, widely dispersed within a mixed temperate forest ecosystem, are predominant features of the Northern Highland area of north-central Wisconsin. A hydrological and biogeochemical investigation of seven of these lakes and their watershed area is currently in progress as part of the Water, Energy, and...
Text and References To Accompany "Map Showing the Thickness and Character of Quaternary Sediments in the Glaciated United States East of the Rocky Mountains"
David R. Soller
1992, Bulletin 1921
A 1:1,000,000-scale map of Quaternary deposits has been compiled for the glaciated area of the United States east of the Rocky Mountains (that is, the area covered by the Laurentide ice sheets). Parts of southern Ontario, areas beneath the Great Lakes, and parts of the submerged eastern seaboard are also...
Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
William E. Reeves, Larry F. Land
1992, Open-File Report 92-160
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area.  Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin.  Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a...
Sedimentology, behavior, and hazards of debris flows at Mount Rainier, Washington
Kevin M. Scott, Patrick T. Pringle, J.W. Vallance
1992, Open-File Report 90-385
Mount Rainier is potentially the most dangerous volcano in the Cascade Range because of its great height, frequent earthquakes, active hydrothermal system, and extensive glacier mantle. Many debris flows and their distal phases have inundated areas far from the volcano during postglacial time. Two types of debris flows, cohesive and...
Simulation of water-table response to management alternatives, central part of the western San Joaquin Valley, California
K.R. Belitz, S.P. Phillips
1992, Water-Resources Investigations Report 91-4193
The occurrence of selenium in agricultural drainwater in the central pan of the western San Joaquin Valley, California, has focused concern on alternatives other than agricultural drains for managing shallow, poor-quality ground water. A transient, three-dimensional, finite-difference ground-water flow model was developed to assess the response of the water table...
Geohydrology of, and simulation of ground-water flow in, the Milford-Souhegan glacial-drift aquifer, Milford, New Hampshire
P. T. Harte, Thomas J. Mack
1992, Water-Resources Investigations Report 91-4177
Hydrogeologic data collected since 1990 were assessed and a ground-water-flow model was refined in this study of the Milford-Souhegan glacial-drift aquifer in Milford, New Hampshire. The hydrogeologic data collected were used to refine estimates of hydraulic conductivity and saturated thickness of the aquifer, which were previously calculated during 1988-90. In...
Flood-frequency characteristics of Wisconsin streams
William R. Krug, Duane H. Conger, Warren A. Gebert
1992, Water-Resources Investigations Report 91-4128
Flood-frequency characteristics for 269 gaged sites on Wisconsin streams are presented for recurrence intervals of 2 to 100 years. Annual flood peaks for the period of record for each gaged site are included. Equations of the relations between flood-frequency and drainage-basin characteristics were developed by multiple-regression analyses. Flood-frequency characteristics for ungaged...
Geohydrologic and chemical data from wells in the Mud Lake area, eastern Idaho, 1988-91
Joseph M. Spinazola, Annette M. Tungate, T. L. Rogers
1992, Open-File Report 92-133
Well information, results of test drilling, water-level measurements in observation wells, and chemical and isotopic constituents in ground-water samples were among the data collected as part of a study of the availability of ground water from the eastern Snake River Plain aquifer system in the Mud Lake area of eastern...
Water resources data, Iowa, water year 1991
D. J. O’Connell, R.B. Lambert, W.J. Matthes, D. Sneck-Fahrer
1992, Water Data Report IA-91-1
Water resources data for the 1991 water year for Iowa consist of records of stage discharge,and water quality of streams; stage, contents, and water quality of lakes and reservoirs; ground water levels and water quality of ground-water wells. This report contains records of water discharge for 118 stream-gaging stations; stage...
