The circulation of water in Flaming Gorge Reservoir is caused chiefly by insolation, inflow-outflow relationships, and wind, which is significant due to the geographical location of the reservoir. During 1970-75, there was little annual variation in the thickness, dissolved oxygen, and specific conductance of the hypolimnion near Flaming Gorge Dam....

This study covers about 1,000 mi2 (2,600 km2 ) of the southern Raft River drainage basin in south-central Idaho and northwest Utah. The main area of interest, approximately 200 mi2 (520 km2 ) of semiarid agricultural and rangeland in the southern Raft River Valley that includes the known Geothermal Resource...

The discovery that ground waters of Egypt's Western Desert are highly corrosive is lost in antiquity. Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native...

This bibliography selectively summarizes investigations to date (1978) dealing with the physical processes of streams in the Arctic. The specialized annotations include aspects of stream processes described in subordinate parts of general papers on the arctic environment and therefore not evident in author-abstract bibliographies. Foreign contributions--Canadian, Scandinavian, and Russian--are summarized,...

Changes in runoff and sediment yield caused by changing sagebrush cover to grass cover were studied at four small watersheds in western Colorado during a 9-year period, from 1965 to 1978. Measurements of runoff and sediment yield from the four watersheds were made for 8 years, at which time two...

Volume 1 of water resources data for the 1978 water year for Hawaii and other Pacific Areas consist of records of stage, discharge, and water quality of streams; and water levels and water quality in wells and springs. This report contains discharge records for 114 gaging stations; water quality for...

Water resources data for the 1978 water year for Idaho consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report in two volumes contains discharge records for 192 gaging...

This report contains statistical summaries of daily streamflow data as of September 30, 1975, for 189 stations west of the Continental Divide in Colorado for use by agencies and individuals engaged in water studies. To be included in this report, a station had to have a minimum of 3 complete...

The proposed Citico Creek Wilderness comprises about 5,670 hectares (56.7 km2) in the Cherokee National Forest south of the Little Tennessee River in easternmost Monroe County, Tennessee. Principal drainages are Citico Creek and Doublecamp Creek. Rocks of the study area include greenschist-facies arkosic metasandstone, metagraywacke, slate, and metaconglomerate of the...

Water resources data for the 1978 water year for Idaho consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report in two volumes contains discharge records for 192 gaging...

Drilling into the San Andreas fault zone has begun in central California as part of the U.S.G.S. program of fault zone studies. The purpose of drilling into the fault zone is threefold. First, it will allow recovery of material from depth in order to determine the composition of both solid...

Proterozoic sedimentary rocks of the Arabian Shield consist of three depositional phases. Phase I (the oldest) includes the Baish, Bahah, and Jiddah groups, which consist of an immature assemblage dominated by fine-grained metagraywacke, graphitic schist, chert, marble, and subordinate polymictic conglomerate and metasiltstone. Clastic rocks of Phase I are composed...

This report updates U.S. Geological Survey Open-File Report 77-780 by including new field data taken in July 1978. A revised geologic map is included, as are new geophysical data from an approximately 0.3-km by 0.5-km area just northeast of and adjoining the area surveyed earlier. The pattern which had been...

The depth to the subject reef has been estimated at a nominal 10 n by three independent analyses based on Landsat and (in two cases) comparisons.: to measured depths of submerged features in the same area. Fathometer readings made in 1979 confirm the 1O-m reading....

For several years, dissolved oxygen in the L'Anguille River has been reduced to concentrations of less than 5.0 milligrams per liter during the summer and fall. The dissolved-oxygen reduction is due only in part to the municipal-waste discharges which enter the river. In addition, concentrations of pesticides have been reported...

The triangular-notch, thin-plate weir is a convenient, inexpensive, and relatively precise flow-measuring instrument. It is frequently used to measure the flow of water in laboratories and in small, natural streams. The purpose of this report is to present a comprehensive analysis of the discharge characteristics of triangular-notch weirs. Previously-published data...

Volume 2 of water resources data for the 1978 water year for other Pacific areas consist of records of stage, discharge, and water quality of streams; stage of a reservoir; and water levels in wells and springs. This report contains discharge records for 44 gaging stations; stage only record for...
