The computer program estimate trend (ESTREND), a system for the detection of trends in water-quality data
Terry L. Schertz, Richard B. Alexander, Dane J. Ohe
1991, Water-Resources Investigations Report 91-4040
Computerized statistical and graphical procedures were developed for use in U.S. Geological Survey (USGS) investigations of trend in stream water-quality data. These procedures, identified as EStimate TREND (ESTREND), are described in this paper to assist USGS investigators involved in multiple-station studies of water-quality trends. Additional discussion focuses on certain statistical...
Sedimentation in Versailles Lake, Ripley County, southeastern Indiana, 1956-88
D.E. Renn, L. D. Arihood
1991, Water-Resources Investigations Report 92-4011
Sedimentation has affected the storage capacity and surface area of Versailles Lake. The lake was constructed by damming Laughery Creek in 1956. At the dam, the drainage area of Laughery Creek is 168 square miles. Locations where the largest amount of sediment has accumulated for the 32-year period 1956-88, are...
Earth-fissure movements associated with fluctuations in ground-water levels near the Picacho Mountains, south-central Arizona, 1980-84
Michael C. Carpenter
1991, Open-File Report 90-561
The Picacho earth fissure transects subsiding alluvial sediments near the east periphery of the Picacho basin in south-central Arizona. The basin has undergone land subsidence of as much as 3.8 meters since the 1930's owing to compaction of the aquifer system in response to ground-water-level declines that have exceeded 100...
Surface water quality assessment of the Upper Illinois River basin in Illinois, Indiana, and Wisconsin: Geochemical data for fine-fraction streambed sediment from high- and low-order streams, 1987
John A. Colman, R. F. Sanzolone
1991, Open-File Report 90-571
Geochemical data are presented from a synoptic survey of 46 elements in fine-fraction streambed sediments of the Upper Illinois River Basin during the fall of 1987. The survey was a component study of the Illinois pilot project of the U.S. Geological Survey's National Water-Quality Assessment program. Most of the sampling...
Quaternary geologic map of the Lake Erie 4 degrees x 6 degrees quadrangle, United States and Canada
David S. Fullerton, Gerald M. Richmond, W.R. Cowan, W. D. Sevon, R. P. Goldthwait, W.R. Farrand, E.H. Muller, R.E. Behling, J.A. Stravers, Gerald Martin Richmond
David S. Fullerton, editor(s)
1991, IMAP 1420(NK-17)
The Quaternary Geologic Map of the Lake Erie 4? x 6? Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that...
Water and tritium movement through the unsaturated zone at a low-level radioactive-waste disposal site near Sheffield, Illinois, 1981-85
P.C. Mills, R. W. Healy
1991, Open-File Report 89-271
The movement of water and tritium through the unsaturated zone was studied at a low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois, from 1981 to 1985. Water and tritium movement occurred in an annual, seasonally timed cycle; recharge to the saturated zone generally occurred in the spring and early...
Changes in chloride concentration in water from municipal wells that tap aquifers in rocks of Cambrian and Ordovician age in northeastern Illinois, 1915–84
G. O. Balding
1991, Water-Resources Investigations Report 90-4116
During the past few decades, several municipalities in northeastern Illinois have noted increases in the salinity of water from wells that tap aquifers in rocks of Cambrian and Ordovician age. The municipalities have discontinued the use of, or sealed-off sections of, those wells. The aquifers involved include the Ancell, the...
Water Resources Data, California, Water Year 1990. Volume 2. Pacific Slope Basins from Arroyo Grande to Oregon State Line except Central Valley
W.F. Shelton, L.F. Trujillo, K.L. Markham, J. R. Palmer
1991, Water Data Report CA-90-2
Water resources data for the 1990 water year for. California consist of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 2 contains discharge records for 125 streamflow-gaging stations and 1 low-flow partial-record station;...
Water Resources Data, California, Water Year 1990. Volume 1. Southern Great Basin from Mexican Border to Mono Lake Basin; and Pacific Slope Basins from Tijuana River to Santa Maria River
J. C. Bowers, R.M. Jensen, E.B. Hoffman
1991, Water Data Report CA-90-1
Water resources data for the 1990 water year for California consist of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 1 contains discharge records for 157 streamflow-gaging stations, 16 crest-stage partial-record streamflow stations,...
Quality-assurance plan for water-resources activities of the U. S. Geological Survey in Montana--1991
Joe A. Moreland
1991, Open-File Report 91-194
As the Nation's principal earth-science information agency, the U.S. Geological Survey has developed a worldwide reputation for collecting accurate data and producing factual, impartial interpretive reports. To ensure continued confidence in the pro- ducts, the Water Resources Division of the U.S. Geological Survey has implemented a policy that all scientific...
