Geology and ground water of the Tualatin Valley, Oregon
D. H. Hart, R. C. Newcomb
1965, Water Supply Paper 1697
The Tualatin Valley proper consists of broad valley plains, ranging in altitude from 100 to 300 feet, and the lower mountain slopes of the drainage basin of the Tualatin River, a tributary of the Willamette River in northwestern Oregon. The valley is almost entirely farmed. Its population is increasing rapidly,...
Identification and measurement of chlorinated organic pesticides in water by electron-capture gas chromatography
William L. Lamar, Donald F. Goerlitz, LeRoy M. Law
1965, Water Supply Paper 1817-B
Pesticides, in minute quantities, may affect the regimen of streams, and because they may concentrate in sediments, aquatic organisms, and edible aquatic foods, their detection and their measurement in the parts-per-trillion range are considered essential. In 1964 the U.S. Geological Survey at Menlo Park, Calif., began research on methods for...
Summary of floods in the United States during 1961
J.O. Rostvedt
1965, Water Supply Paper 1810
This report describes the most outstanding floods in the United States during 1961. The most damaging floods during the year were those caused by snowmelt in March and April in the upper Mississippi River basin and those accompanying Hurricane Carla in September.Hurricane Carla traveled northward along the east edge of...
Ground and surface water in the Mesabi and Vermilion Iron Range area, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-A
Within the Mesabi-Vermilion Iron Range area, water of good quality is available from the Biwabik Iron-Formation, from stratified drift, and from lakes and streams. About 700 bgy (billion gallons a year) leaves the area as surface water, of which about one-third comes from ground water. Leached, oxidized, and fractured parts of...
Ground-water in the upper Star Valley, Wyoming
Eugene H. Walker
1965, Water Supply Paper 1809-C
The upper Star Valley covers about 55 square miles of lowland in the westernmost part of Wyoming. The altitude of the floor of the valley is 6,000-6,700 feet. The climate is cool; the growing season, short. Annual precipitation averages about 18 inches, and total precipitation in July and August averages...
Summary of floods in the United States during 1960
J.O. Rostvedt
1965, Water Supply Paper 1790-B
This report describes the most outstanding floods in the United States during 1960. No major floods occurred during the year, although two floods caused severe damage the first in March and April in eastern Nebraska and adjacent areas, and the second in September in Puerto Rico.Unseasonal rains in mid-March caused...
Geology and hydrology of the Claiborne Group in western Tennessee
Gerald K. Moore
1965, Water Supply Paper 1809-F
The area of western Tennessee underlain by the Claiborne Group is about 7,200 square miles and lies on the east flank of the syncline that forms the Mississippi embayment. It includes the Mississippi Alluvial Plain and part of a dissected upland plateau. The Claiborne Group dips to the northwest at...
Determination of uranium in natural waters
Franklin Butt Barker, J. O. Johnson, K.W. Edwards, B.P. Robinson
1965, Water Supply Paper 1696-C
A method is described for the determination of very low concentrations of uranium in water. The method is based on the fluorescence of uranium in a pad prepared by fusion of the dried solids from the water sample with a flux of 10 percent NaF 45.5 percent Na2CO3 , and...
Specific yield - laboratory experiments showing the effect of time on column drainage
Robert C. Prill, A.I. Johnson, Donald Arthur Morris
1965, Water Supply Paper 1662-B
The increasing use of ground water from many major aquifers in the United States has required a more thorough understanding of gravity drainage, or specific yield. This report describes one phase of specific yield research by the U.S. Geological Survey's Hydrologic Laboratory in cooperation with the California Department of Water...
Ground-water resources of Pavant Valley, Utah
R. W. Mower
1965, Water Supply Paper 1794
Pavant Valley, in eastern Millard County in west-central Utah, is in the Great Basin section of the Basin and Range province. The area of investigation is 34 miles long from north to south and 9 miles wide from east to west and comprises about 300 square miles. Agriculture, tourist trade,...
Suitability of irrigation water and changes in ground-water quality in the Lompoc subarea of the Santa Ynez River Basin, Santa Barbara County, California
R. E. Evenson
1965, Water Supply Paper 1809-S
Analyses of water samples collected since 1934 from some of the irrigation wells in the Lompoc subarea of the Santa Ynes River valley have shown a gradual deterioration in the chemical quality of the water. Most of the ground water pumped in the subarea has a dissolved-solids contents ranging from about...
Water resources in the vicinity of municipalities on the eastern Mesabi Iron Range and the Vermilion Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-F
Additional supplies of water are available near the municipalities on the eastern Mesabi Iron Range and the Vermilion Iron Range. On the eastern Mesabi Range the potential for additional development of both ground-water and surface-water supplies are good, and on the Vermilion Range the best potential for development is from...
