Field conditions at the Maricopa Agricultural Center, Pinal County, Arizona, September 28, 1989
Sandra J. Owen-Joyce
1989, Open-File Report 89-590
Field conditions were documented during the Landsat and SPOT satellite overpasses of the Maricopa Agricultural Center, Pinal County, Arizona, on September 28, 1989. Crop types were mapped and photographed for each demonstration farm field, and irrigation, cultivation, and orientation of rows are described. Field and photographic descriptions are presented in...
Characteristics and trends of streamflow and dissolved solids in the upper Colorado River Basin, Arizona, Colorado, New Mexico, Utah, and Wyoming
Timothy D. Liebermann, David K. Mueller, James E. Kircher, Anne F. Choquette
1989, Water Supply Paper 2358
Annual and monthly concentrations and loads of dissolved solids and major constituents were estimated for 70 streamflow-gaging stations in the Upper Colorado River Basin. Trends in streamflow, dissolved-solids concentrations, and dissolved-solids loads were identified. Nonparametric trend-analysis techniques were used to determine step trends resulting from human activities upstream and long-term...
Preparation of average annual runoff map of the United States, 1951-80
W.R. Krug, W.A. Gebert, D.J. Graczyk
1989, Open-File Report 87-535
Average annual runoff was computed or estimated for 2,148 hydrologic cataloging units in the United States and Puerto Rico , for the period 1951-80. Runoff was computed from the recorded streamflow at 5,951 U.S. Geological Survey gaging stations. The runoff at more than 3,000 of these stations was estimated by...
Quality of bottom material and elutriates in the lower Willamette River, Portland Harbor, Oregon
Gregory J. Fuhrer
1989, Water-Resources Investigations Report 89-4005
In October 1983 the U.S. Geological Survey, in cooperation with the U.S. Army Corp of Engineers, collected bottom-material and water samples from Portland Harbor, Oregon to determine concentrations of trace metals and organic compounds in elutriate-test filtrate and bottom material. Of the trace metals examined in bottom material, concentrations of...
Hydrogeology of the Leadville limestone and other paleozoic rocks in northwestern Colorado, with results of aquifer tests at Glenwood Springs
Arthur L. Geldon
1989, Water-Resources Investigations Report 87-4195
Paleozoic rocks in northwestern Colorado were investigated during the U.S. Geological Survey 's Regional Aquifer Systems Analysis of the Upper Colorado River Basin. Paleozoic rocks in the study area are grouped into 11 hydrostratigraphic units on the basis of lithologic and hydrologic properties. Devonian and Mississippian carbonate rocks and Pennsylvanian...
Measurement of time of travel in streams by dye tracing
F. A. Kilpatrick, James F. Wilson
1989, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...
Preliminary assessment of sources, distribution, and mobility of selenium in the San Joaquin Valley, California
R. J. Gilliom
1989, Water-Resources Investigations Report 88-4186
Selenium in tile drain water from parts of the western San Joaquin Valley, California, has adversely affected fish and waterfowl where drain water was impounded. Soils in these drained areas were derived from Coast Range marine sedimentary formations, were naturally saline and probably contained abundant soluble selenium. Decades of irrigation...
Chemical characteristics, including stable-isotope ratios, of surface water and ground water from selected sources in and near East Fork Armells Creek basin, southeastern Montana, 1985
R. F. Ferreira, J. H. Lambing, R. E. Davis
1989, Water-Resources Investigations Report 89-4024
Water samples were collected from 29 sites to provide synoptic chemical data, including stable-isotope ratios, for an area of active surface coal mining and to explore the effectiveness of using the data to chemically distinguish water from different aquifers. Surface-water samples were collected from one spring, four sites on East...
The vertical distribution of selected trace metals and organic compounds in bottom materials of the proposed lower Columbia River export channel, Oregon, 1984
Gregory J. Fuhrer, Arthur J. Horowitz
1989, Water-Resources Investigations Report 88-4099
A proposal to deepen the lower Columbia River navigation channel in Oregon prompted a study of the vertical distribution of selected trace metals and organic compounds in bottom sediments. These data are needed to evaluate the effects of dredging and disposal operations. Elutriation testing of bottom material indicated chemical concentrations...
Geohydrology of the alluvial and terrace deposits of the North Canadian River from Oklahoma City to Eufaula Lake, central Oklahoma
J.S. Havens
1989, Water-Resources Investigations Report 88-4234
This investigation was undertaken to describe the geohydrology of the alluvial and terrace deposits along the North Canadian River between Lake Overholser and Eufaula Lake, an area of about 1,835 square miles, and to determine the maximum annual yield of ground water. A 1982 water-level map of the alluvial and terrace...
Hydrogeology and results of aquifer tests in the vicinity of a hazardous-waste disposal site near Byron, Illinois
Robert T. Kay, David N. Olson, Barbara J. Ryan
1989, Water-Resources Investigations Report 89-4081
The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, conducted an investigation of a Superfund Site near Byron, Illinois. The purpose of the investigation was to determine the hydrogeologic properties of the Galena-Platteville and St. Peter aquifers, the primary water-supply aquifers for domestic supply in the area....
Geochemistry of artificial-recharge tests in the Oakes aquifer near Oakes, southeastern North Dakota
G. F. Huff, J. D. Wald
1989, Water-Resources Investigations Report 89-4122
As part of an artificial-recharge feasibility study, water from the James River was introduced into the Oakes aquifer of southeastern North Dakota by infiltration through a recharge basin. Chemical composition of water in the recharge basin and ground water from two separate flow paths beneath the basin was determined from...
Trends in selected water-quality characteristics, Flathead River at Flathead, British Columbia, and at Columbia Falls, Montana, water years 1975-86
L. E. Cary
1989, Water-Resources Investigations Report 89-4054
Data for selected water quality variables were evaluated for trends at two sampling stations--Flathead River at Flathead, British Columbia (Flathead station) and Flathead River at Columbia Falls, Montana (Columbia Falls station). The results were compared between stations. The analyses included data from water years 1975-86 at the Flathead station and...
