From purpose and scope: The purpose of this investigation is to evaluate, through electrical analog model simulation, the effects of two specific water-management proposals in Dade County. Proposal one is the installation of a secondary control on Snake Creek Canal and proposal two is the forward pumping scheme.

The following report presents a regional study of the extent, thickness, lithology, stratigraphic relations, age, depositional environment, and tectonic history of thick sulfate deposits and associated salts of sodium and potassium.

Report and Geographic Survey. Report reveals "relations for estimating peak flows and mean annual flow for natural streams in Wyoming using the channel-geometry method and basin-characteristics method. Also includes maps, graphs, and photographs.

From introduction: The purpose of this report is to describe low-flow characteristics of streams in the lower Wisconsin River basin where streamflow data have been collected and to present equations for estimating low-flow characteristics and ungaged sites.

From abstract: The seismic history of the southeastern United States is dominated by the 1886 earthquake near Charleston, S.C. An understanding of the specific source and the uniqueness of the neotectonic setting of this large earthquake is essential in order to properly assess seismic hazards in the southeastern United States. Such knowledge will also contribute to the fundamental understanding of intraplate earthquakes and will aid indirectly in deciphering the evolution of Atlantic-type continental margins. The 15 chapters in this volume report on the first stage of an ongoing multidisciplinary study of the Charleston earthquake of 1886.

The following report follows a mineral survey of the Glacier Primitive Area and adjoining area in Wyoming, that was made in 1968 and 1969.

From abstract: New stratigraphic nomenclature for units within the Columbia River Basalt Group is introduced to revise and expand that currently in use; it is based largely on subdivisions made informally by T. L. Wright, M. J. Grolier, and D. A. Swanson in 1973. The Yakima Basalt is raised to subgroup status, and three formations-the Grande Ronde Basalt, Wanapum Basalt, and Saddle Mountains Basalt, in order of decreasing age-are defined within it.

A report regarding the general geology and mines of the East Titanic Mining District, in Tuah and Juab Counties, Utah.

A bibliography that lists about 1,300 U.S. Geological Survey publications related to coal and published prior to January 1, 1971.

Report providing information about the water resources of the Munabo Valley in southeastern Puerto Rico, including the principal source of water, chemical composition, hydraulic conductivities, average transmissivity, and suggestions for water supplementation.

An index of fossil names between 1820 and 1965. Diatoms, spores, and pollen are excluded from this index.

From introduction: The purpose of this report is to describe the hydrologic system in the Lake Wingra basin, with particular emphasis on the hydrolic budget of the lake itself.

Abstract: The High Plains of the eastern New Mexico region are recognized as an abundant and varied source of natural resources. This bibliography of over 1,900 references concerned with geology, hydrology, chemistry, and geography has been compiled to assist physical science researchers in their study of this region.

From introduction: This report describes a numerical model that is rigorous in its solution to the equations yet simple enough that it may be used and understood by a knowledgeable ground-water hydrologist or engineer.

A report about the stratigraphic nomenclature changes in geology.

From introduction: This report summarizes data currently available to obtain low-flow characteristics for Minnesota streams. The data include expected annual low-flows for specific recurrence intervals at 161 continuous-record gaging stations.

Abstract: This report contains lists of stations at which the U.S. Geological Survey collects water data either on a continuous basis or at least on a daily basis. The files contain daily values for streamflow, reservoir levels or contents, water temperatures, specific conductance, sediment discharge plus data for several other quality parameters that are measured by means of monitoring equipment or result from analyses of samples collected on a daily basis. The stations are listed according to station number within each State. The report lists the availanle retrieval options, the machine -readable output options, user charges and how to obtain data.
