With the emission spectrograph, the analyst is able to determine many minor elements simultaneously in water samples. Spectrographic methods differ chiefly in techniques of preconcentrating the elements. For waters with dissolved solids of less than 1,000 milligrams per liter, the method of evaporating to dryness and determining the elements in the dried residue is sensitive, precise, and reasonab

This report lists the streamflow and reservoir stations in the Snake River basin for which records have been or are to be published in reports of the Geological Survey for periods through September 30, 1970. It supersedes Geological Survey Circular 583. It was updated by personnel of the Data Response Unit, Water Resources Division, Geological Survey.

This report lists the streamflow and reservoir stations in The Great Basin for which records have been or are to be published in reports of the Geological Survey for periods through September 30, 1970. It supersedes Geological Survey Circular 580. It was updated by personnel of the Data Reports Unit, Water Resources Division, Geological Survey.

A nationwide reconnaissance of selected minor elements in water resources of the 50 States and Puerto Rico was made by the U.S. Geological Survey in cooperation with the U.S. Bureau of Sport Fisheries and Wildlife during autumn, 1970. Initiated in response to the growing need for data on minor elements in water, including toxic metals, the synoptic survey provides an up-to-date baseline of such da

Data collected during the prelogging period 1959-65 indicate an average annual runoff for Needle Branch and Deer and Flynn Creeks of 74.2, 75.1, and 77.7 inches, respectively. The measured precipitation at Flynn Creek of 92.9 inches was 5 inches less than at either Needle Branch or Deer Creek. Unit flood runoff during the prelogging period was found to be lowest on Flynn Creek and highest on Needl

In a recent article in "Science" discussing the Environmental Policy Act of 1969, Gillette (1971) states "The law's instructions for preparing an impact report apparently are not specific enough to insure that an agency will fully, or even usefully, examine the environmental effects of the projects it plans." This report contains a procedure that may assist in developing uniform environmental impa

Since the dawn of civilization waterfront land has been an irresistible attraction to man. Throughout history he has sought out locations fronting on oceans, rivers, and lakes. Originally sought for proximity .to water supply and transportation, such locations are now sought more for their esthetic qualities and for recreation. Usable natural waterfront property is limited, however, and the more d

The floods of December 1964 and January 1965 in the Far Western States were extreme; in many areas, the greatest in the history of recorded streamflow and substantially greater than those of December 1955. An unusually large area--Oregon, most of Idaho, northern California, southern Washington, and small areas in western and northern Nevada--was involved. It exceeded the area flooded in 1955. Outs

This report summarizes stream-temperature data collected by the U.S. Geological Survey in cooperation with the State of North Carolina during the period 1943-67. Listed in two tables are summary values determined from records from 176 locations throughout the State. Of the 850 station years of record, 31 percent is monthly records, 50 percent is daily, and 19 percent is continuous. Table

This report summarizes water-quality data collected by the U.S. Geological Survey in cooperation with the State of North Carolina during the period 1943-67. Maximum, minimum, and average values are shown for complete analyses of mineral constituents dissolved in water from 177 locations at which samples were collected daily or monthly for at least 1 consecutive year. Maximum and minimum values

Water for irrigation is needed to improve crop yields from sandy soils in the Brooten-Belgrade area. Ground-water supplies of sufficient quantity and suitable quality for irrigation are available in much of the area. Quaternary glacial drift, as much as 300 feet thick, is underlain by Precambrian crystalline rocks and possibly by Cretaceous sedimentary rocks. Sand and gravel aquifers are buried at

In the Lake Emily area, thickness of the glacial drift ranges from about 200 feet to more than 400 feet. Within the drift are sand and gravel aquifers, some of which can yield adequate water supplies for irrigation. Outwash, as much as 60 feet thick, lies at the surface. The outwash has saturated thicknesses of more than 40 feet and transmissivities of more than 50,000 gallons per day per foot loc
