Water-resources investigations of the U.S. Geological Survey in Missouri consist of collecting hydrologic data and conducting interpretive investigations. The data and the results of the investigations are published or released by either the U.S. Geological Survey or by cooperating agencies. This report describes the data-collection activities and investigations in Missouri...

The Gainesville Lock and Dam is the first of ten lock and dam projects on the Tennessee-Tombigbee Waterway to be completed. The structure was completed in 1978 and filling of the reservoir commenced March 20, 1978 resulting in changes in stream stage and discharge, ground-water levels, and chemical quality of...

Four flood-control reservoirs, Green River Lake, Nolin River Lake, Barren River Lake, and Rough River Lake, were completed in the Green River basin of Kentucky between 1959 and 1969. A digital computer model of these reservoirs and the stream reaches from the reservoirs downstream to the Green River at Calhoun,...

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,...

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...

During the period April 1975 to June 1978, the U.S. Geological Survey conducted a river-quality assessment of the Upper Chattahoochee River basin in Georgia. One objective of the study was to assess the magnitudes, nature, and effects of point and non-point discharges in the Chattahoochee River basin from Atlanta to...

A scheme is presented which used adsorption chromatography with pH gradient elution and size-exclusion chromatography to concentrate and separate hydrophobic organic acids from water. A review of chromatographic processes involved in the flow scheme is also presented. Organic analytes which appear in each aqueous fraction are quantified by dissolved organic...

Population growth and the potential development of subsurface mineral resources have increased the need for information on the availability and quality of ground water on the Southern Ute Indian Reservation. The U.S. Geological Survey, in cooperation with the Southern Ute Tribal Council, the Four Corners Regional Planning Commission, and the...

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...

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...

The Bonneville Salt Flats and Pilot Valley are in the western part of the Great Salt Lake Desert in northwest Utah. The areas are separate, though similar, hydrologic basins, and both contain a salt crust. The Bonneville salt crust covered about 40 square miles in the fall of 1976, and...

On October 31, November 1 and 3, 1978, forty-eight gravity stations were established near Helena, in the Broadwater geothermal area, west-central Montana (fig. 1)....

A revised version of Graphic Normative Analysis Program (GNAP) has been developed to allow maximum flexibility in the evaluation of chemical data by the occasional computer user. GNAP calculates ClPW norms, Thornton and Tuttle's differentiation index, Barth's cations, Niggli values and values for variables defined by the user. Calculated values...

A study of ground-water availability in the Gatlinburg area, Tenn., was undertaken to improve concepts of ground-water occurrence in the Blue Ridge and demonstrate that ground water is present in sufficient quantities to provide an alternative to surface water as a source of supply. Of 25 test wells, 8 produced...

The Big John caldera is a small subsidence structure in the Marysvale volcanic field, high along the western flank of the Tushar Mountains in west-central Utah (fig. 1). This caldera formed 22 m.y. ago in response to ash-flow eruptions of the Delano Peak Tuff Member of the Bullion Canyon Volcanics....

The structure and stratigraphy of the Florida-Hatteras Slope and inner Blake Plateau was studied by means of 4,780 km of single-channel air gun seismic reflection profiles. Control for the seismic stratigraphy is provided by correlating reflecting units and paleontologically dated stratigraphic units identified in offshore wells and dredge hauls. Many...

This report documents hydrologic and meteorologic aspects of flooding in northeastern and central New Jersey during November 8-10, 1977. Peak stages and discharges at 51 streamflow gaging sites are tabulated and compared to previous maximums. High-water flood crest elevations are presented for eight stream reaches in or near Bergen County...

A ground water quality monitoring network is proposed for Idaho. The network comprises 565 sites, 8 of which will require construction of new wells. Frequencies of sampling at the different sites are assigned at quarterly, semiannual, annual, and 5 years. Selected characteristics of the water will be monitored by both...

The Santa Ynez Indian Reservation is situated above a bedrock ridge that forms the southern boundary of the Santa Ynez upland ground-water basin. A pumping depression exists upgradient from the reservation, and water levels have declined an average of 1.0 to 1.5 feet per year since the 1940's. This decline...
