From Introduction: "The data presented here are reconnaissance data intended for use in identifying broad areas for further study. While care has been taken to provide reliable sampling and analyses, verification of individual analyses is beyond the scope of this report. The data should be viewed statistically because "one-point anomalies" may be misleading. Regional trends, however, should be reliable."

From Introduction: "The Pocatello 1º x 2º Quadrangle, Idaho (Fig. 1), was evaluated to identify geologic environments and to delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were evaluated primarily on the basis of surface investigations, because only limited subsurface data were available."

From Introduction: "The Bozeman Quadrangle is south-central Montana was evaluated for geologic environments capable of containing uranium deposits to a depth of 1500 m (5,000 ft.). Most rock types and geographic areas were investigated by surface traverse, and hydrgeochemical data were collected from available well sites."

From Purpose and Scope: "The Wells 2º Quadrangle, Nevada, Utah, and Idaho (Fig. 1), was evaluated to identify and delineate areas and geologic environments that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments in the quadrangle were evaluated to a depth of 1500 m (5,000 ft) using all available surface and subsurface data."

From Introduction: "The Crystal City Quadrangle, Texas, was evaluated to a depth of 1500 m (5,000 ft) to identity geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From summary: This report contains data collected during a geochemical survey for uranium in the Ashton National Topographic Map Series (NTMS) quadrangle of eastern Idaho, southwestern Montana, and northwestern Wyoming (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide lydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From summary: This report contains data collected during a geochemical survey for uranium in the St. Johns National Topographic Map Series (NTMS) quadrangle of Arizona/New Mexico (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From introduction: This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Thermopolis National Topographic Map Series (NTMS) quadrangle, Wyoming, by the Los Alamos Scientific Laboratory (LASL).

From Introduction: "The Laredo Quadrangle, Texas (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From abstract: Results of a reconnaissance geochemical survey of the Alliance Quadrangle are reported. Field and laboratory data are presented for 543 groundwater and 523 stream sediment samples.

From purpose and scope: The purpose of this study was to update hydrologic data and refine understanding of the hydrologic system within the San Dieguito, San Elijo, and San Pasqual hydrologic subareas in San Diego County, Calif., and to evaluate the suitability of these areas for reclaimed water use.

From abstract: This report provides "hydrologic information for the north-central and western coal-mining regions of Missouri . . . to define the hydrologic system in these areas of major historic and planned coal development." It "describes the physical setting, climate, coal-mining practices, general hydrologic systems, and the current (1980) hydrologic data base in these two coal-mining regions."

Abstract: The primary effect of a floodwater-retarding structure (FRS) on the flow of Trout Creek, Wisconsin, is attenuation of flood peaks. Reduction of flood peaks ranged from 58 to 91 percent during the study period, 1975 to 1979. An inverse relationship exists between sediment concentration and outflow from the FRS during floods. Most sediment stored in the flood pool during floods is released from the reservoir during subsequent reduced discharge. Sediment-trapping efficiency of the FRS was 7 percent during the 4-year study. The bankfull capacity of the channel was reduced from 154 cubic feet per second upstream from the FRS to 65 cubic feet per second downstream. Mean bankfull depth downstream from the FRS has adjusted to a value 45 percent less than upstream from the structure due to the sedimentation of materials transported from the FRS during reduced flows. The FRS was not found to have any significant adverse effect on the arthropod fauna or trout reproduction in Trout Creek from 1975 to 1979. During 1960-1979, winter floods seem to have had the greatest adverse effect on the survival of brown trout eggs and sac fry.

From introduction: The purpose of this report is to describe the general quality and quantity of water in the principal water-supply aquifers in Minnesota.

This report analyses resistivity and porosity logs to determine water-quality trends in carbonate aquifers. It contains tables and other figures.

This report uses data collected from seventeen lakes and ponds in Eagan, Minnesota from 1972 through 1978 to determine the effects of urbanization on water quality. It contains a map, graphs, and tables.

A report regarding the Alabama coastal ecological characterization atlas study, the purpose of which is to provide information concerning the biological, physical, and social conditions in coastal Alabama.
