Hydrologic data for Little Elm Creek, Trinity River Basin, Texas, 1974
R.M. Slade Jr., J.M. Taylor
1976, Report
The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...
Map showing ground-water conditions in the Aravaipa Valley area, Graham and Pinal Counties, Arizona-1975
J. A. Gould, R. P. Wilson
1976, Water-Resources Investigations Report 76-107
This hydrologic map of the Aravaipa Valley area includes about 500 sq mi in southeastern Arizona. Development of the ground-water resources is small, and pumpage is estimated to be less than 3,000 acre-ft annually for irrigation, livestock, and domestic uses. Hydrographs of the water level in selected wells show no...
Atomic absorption spectrometric determination of copper, zinc, and lead in geological materials
R. F. Sanzolone, T. T. Chao
1976, Analytica Chimica Acta (86) 163-168
An atomic absorption spectrometric method is described for the determination of copper, zinc, and lead in geological materials. The sample is digested with HF—HCl—H2O2; the final solution for analysis is in 10 % (v/v) HCl. Copper and zinc are determined directly by aspirating the solution into an air—acetylene flame. A...
Simulation of streamflow of Flambeau River at Park Falls, Wisconsin to define low-flow characteristics
William R. Krug
1976, Water-Resources Investigations Report 76-116
Daily streamflows of the Flambeau River at Park Falls, Wisconsin , were simulated for a 31-year period. Streamflow was simulated using a streamflow-routing model. These simulated daily flows were analyzed for summer (June 1-October 31) low-flow frequency. The resultant 7-day, 10-year summer low flow is 260 cubic feet per second....
Conditions in the deeper parts of the hot spring systems of Yellowstone National Park, Wyoming
Alfred Hemingway Truesdell, Robert O. Fournier
1976, Open-File Report 76-428
Yellowstone thermal areas are scattered over an area of nearly 50 x 60 kilometers (Fig. 1) and contain waters of diverse compositions. This has lead to the implicit assumption that Yellowstone consisted of discrete hydrothermal systems (e.g., Fournier and Truesdell, 1970). It is the purpose of this paper to suggest...
Annual report to the Pecos River Commission on investigations being made in New Mexico and Texas by the United States Geological Survey in cooperation with the Pecos River Commission: calendar year 1976
Water Resources Division, U.S. Geological Survey
1976, Report
This report describes investigations in New Mexico and Texas made by the Water Resources Division of the U.S. Geological Survey in cooperation with the Pecos River Commission during the 1976 calendar year and provides a summary of costs for the fiscal year ending June 30, 1976....
Radiocarbon dates indicate rates of graben downfaulting, San Jacinto Valley, California
B. E. Lofgren, Meyer Rubin
1975, Journal of Research of the U.S. Geological Survey (3) 45-46
Recent radiocarbon dates for wood samples collected from three depths in San Jacinto Valley graben indicate active tectonic downfaulting during the past 42,000 yr. The flood plain of graded San Jacinto River, entering the valley from the southeast and leaving toward the west, serves as a reference datum across the...
