Hot springs of the central Sierra Nevada, California
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-559
Thermal springs of the central Sierra Nevada issue dilute to slightly saline sodium chloride, sodium bicarbonate, or sodium mixed-anion waters ranging in pH from 6.4 to 9.3. The solubility of chalcedony appears to control the silica concentration in most of the spring waters. Fales Hot Springs may be associated with...

1977, Miscellaneous Field Studies Map 820
In the period 1964 to 1974, the U.S. Geological Survey conducted various seismic reflection and rock-sampling cruises in the continental borderland of southern California. This map report, on two near-shore basins, the Santa Monica and the San Pedro (sheet 1, figs. 1 and 2), is based on data obtained during...

Assessment of increased thermal activity at Mount Baker, Washington, March 1975-March 1976
David Frank, Mark Frederick Meier, Donald A. Swanson, James W. with contributions by Babcock, Marvin O. Fretwell, Stephen D. Malone, Charles L. Rosenfeld, Ronald L. Shreve, Ray E. Wilcox
1977, Professional Paper 1022-A
In March 1975 Mount Baker showed a large increase in thermal emission, which has persisted for more than 1 year. Fumarole ejecta accompanied the thermal activity from March to September, but the ejecta had no constituents that suggest a magmatic source. Estimates of that part of the total heat flux...

Application of a rainfall-runoff model in estimating flood peaks for selected small natural drainage basins in Texas
B.C. Massey, Elmer E. Schroeder
1977, Open-File Report 77-792
A parametric rainfall-runoff simulation model was used to synthesize long-term records of annual peak discharges for small natural drainage basins in Texas. Optimum model-parameter values were determined for each of the 40 basins studied by using short-term rainfall, evaporation, and discharge data. The calibrated model was used in conjunction with...
Chemical, isotopic, and gas compositions of selected thermal springs in Arizona, New Mexico, and Utah
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-654
Twenty-seven thermal springs in Arizona, New Mexico, and Utah were sampled for detailed chemical and isotopic analysis. The springs issue sodium chloride, sodium bicarbonate, or sodium mixed-anion waters of near neutral (6.2) to alkaline (9.2) pH. High concentrations of fluoride, more than 8 milligrams per liter, occur in Arizona in...
Development of ground water in the Houston District, Texas, 1970-74
R.K. Gabrysch
1977, Open-File Report 77-413
Total withdrawals of ground water in the Houston district, Texas , increased 9 percent from about 488 million gallons per day in 1970 to about 532 million gallons per day in 1974. The average annual rate of increase from 1960 to 1969 was about 6.3 percent. During 1970-74, increases in...
Descriptions and chemical analyses for selected wells in eastern Sacramento Valley, California
Ronald P. Fogelman, Gerald L. Rockwell
1977, Open-File Report 77-486
The Sacramento Valley occupies the northern one-third of the Great Central Valley of California. The study area of this report includes about 1,300 square miles in the eastern part of the Sacramento Valley, extending from the latitude of Roseville on the south to the latitude of Chico on the north...
Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...
Geohydrology of part of the Round Valley Indian Reservation, Mendocino County, California
K. S. Muir, Dwight Albert Webster
1977, Water-Resources Investigations Report 77-22
The Round Valley Indian Reservation in northern California obtains most of its water from the ground-water reservoir. The ground-water reservoir is made up of continental deposits, alluvium, and stream-channel deposits ranging in age from Pliocene to Holocene. Most of the water is pumped from the alluvium. Most ground water (about...

1977, Open-File Report 77-128
This report describes the quality of the surface and ground waters of the Yakima Indian Reservation in south-central Washington, during the period November 1973-October 1974. The average dissolved-solids concentrations ranged from 48 to 116 mg/L (milligrams per liter) in the mountain streams, and from 88 to 372 mg/L in the...

1977, Open-File Report 77-642
The coastal parts of Pasco, Pinellas and Hillsborough are undergoing extensive urban development. The Floridan aquifer is the area 's principal water supply. Potentiometric and water-table maps were prepared in order to determine the effect of groundwater withdrawals in selected well fields in west-central Florida. These maps were prepared in...
A synoptic survey of trace metals in bottom sediments of the Willamette River, Oregon
David A. Rickert, V. C. Kennedy, S. W. McKenzie, W. G. Hines
1977, Circular 715-F
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
