From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

Abstract: The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information requires knowledge of the information in the data base and an assessment of the potential for improving the accuracy of data-transfer mechanisms. The analytical technique known as Network Analysis for Regional Information is used to assess acquired streamflow information and to evaluate its transferability within previously determined regions of homogenous streamflow characteristics. Regression equations that relate low-, mean-, and flood-flow characteristics to basin parameters are the data-transfer mechanisms used in the evaluation. This analysis showed that only minor improvements in the regression equations can be expected after 20 additional years of data collection at gages in the 1980 program. Transfer mechanisms with less model error are needed for improved data transferability. A more efficient program can be achieved by discontinuing selected gages in the planning-and-design network. To this end, 11 continuous-record and 25 partial-record gages were selected to be discontinued by April 1, 1980. Additionally, …

Introduction: The alluvial deposits form the principal aquifer in the Owl Creek Valley and the source of water to many stock and domestic wells and to a few irrigation wells. In 1975, the U.S. Geological Survey, in cooperation with the Wyoming State Engineer, began an investigation of the hydrology and geology, including the geomorphology, of Owl Creek Valley (fig. 1) to determine possible favorable areas for obtaining ground water of adequate chemical quality for irrigation and other uses. The part of Owl Creek basin investigated is downstream from Anchor Reservoir and includes North Fork, South Fork, and the mainstem of Owl Creek (pi. 1). However, the area downstream from Embar Ranch (pi. 1) was emphasized during the study.

From introduction: In 1971, the U.S. Geological Survey (USGS) began a cooperative study to measure stream discharge, suspended-sediment load, and chemical quality of surface waters draining the project area. In 1976, the study was expanded to include measurement of ground-water levels and quality. The general hydrologic system in the vicinity has been described by Patterson, Fuentes, and Toler (1982).

Data collected as part of a hydrogeochemical and stream sediment reconnaissance in Phoenix, Arizona including laboratory data on waters and sediments as well as field data.

From introduction: This bibliography was compiled to provide a source of information on the ecology of the co-occurring tunas and dolphins in the Eastern Tropical Pacific (ETP). While some of the articles give information concerning distribution and ecology of tunas and dolphins in other geographic areas, the primary focus is on the tunas and dolphins that occur together in the ETP.

From abstract: This report presents the results of biologic investigations by the U.S. Geological Survey and the Wisconsin Department of Natural Resources during a study of hydrology and water quality in a small drainage basin in the "Driftless Area" of southwest Wisconsin. The investigation included aquatic macrophytes, periphytic and planktonic algae, benthic invertebrates, and trout population dynamics during 1967-78.

From abstract: A two-dimensional digital model of the ground-water-flow system was constructed to test the conceptual model of the system ad to study the effects of development on ground-water levels and flow in the White River.

Report issued by the National Bureau of Standards over thermal tests conducted on soil samples. The results of the laboratory tests are discussed. This report includes tables, illustrations, photographs.

This report presents an assessment of water resources and data-network of the Manasota Basin located in Manatee and Sarasota counties in Florida.

From purpose and approach of study: The purpose of this study was to develop a predictive model of the ground-water system for use as a management tool. The model will be used by State and local officials in evaluating the effects of alternative methods of controlling or developing the ground-water resources of the Big Sioux aquifer in Minnehaha County.

From purpose and scope: The purpose of this study, done in cooperation with the U.S. Bureau of Indian Affairs, was to provide hydrologic information necessary to aid in evaluating the feasibility of developing a water supply for the Twenty-Nine Palms Indian Reservation.

From objectives: In the Salton Sea Quadrangle, reported uranium occurrences were evaluated, and geologic environments thought to be favorable were examined. This report includes the field data collected during that work and a summary of the quadrangle geology and uranium favorability. This is the final report to be prepared on this quadrangle under the NURE program.

Appendices containing data on uranium availability in the Salton Sea Quadrangle in addition to tabulated chemical and water analyses to accompany a report on U.S. uranium resources in California and Arizona.

Introduction: The Hylas Zone, a northeast-trending belt of mylonite and ultramylonite, lies in the eastern Piedmont Province of Virginia and borders the northern end of the Richmond Basin (Fig. I-1). The north-trending Richmond Basin is 58 km long and a maximum of 16 km wide. Early indications of anomalous uranium concentrations in the region came from discussions with Jan Krason, GeoExplorers International, Denver, who had worked in the area. Examination of aerial radiometric data (Geodata International, 1975) and HSSR data (Cook, 1981) indicated anomalous values of uranium in the area northwest of Richmond. During June 1981, a 5-day trip to the Hylas area was undertaken to collect rock and ground-water samples and to identify possible source and host rocks of uranium.

Abstract: A modern adaptation of an old fishing technique is gaining recognition in the Pacific and elsewhere as an effective means to increase fishing productivity in the open sea. The use of man-made, free-floating, and anchored floating devices to aggregate pelagic fishes for subsistence, recreational and commercial fishing has increased markedly in recent years; estimates of deployed and planned units exceed 1,000. These devices have been anchored in depths ranging from several hundred to several thousand fathoms. This report reviews the development and present use of fish aggregating devices in the Pacific and Indian Oceans.

From purpose and scope: The purpose of the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy (DOE) is to identify and delineate areas and environments within the Aztec 10X20 Quadrangle, New Mexico and Colorado, that exhibit characteristics favorable for the occurrence of uranium deposits that have the potential to contain at least 100 metric tons U3 08 total endowment with a minimum grade of 100 ppm (0.01 percent) U3 08 . Evaluation is based on geochemical, mineralogic, hydrologic, aerial radiometric, sedimentologic, and general geologic characteristics of the formations in the quadrangle.
