"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).

Report of elemental date from a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Hamilton National Topographic Map Series (NTMS) quadrangle in Montana/Idaho: "The HSSR is part of the United States Department of Energy's National Uranium Resource Evaluation (NURE), which is designed to provide improved estimates of the availability and economics of nuclear fuel resources and make available to industry information for use in the development and production of uranium resources" (p. 1).

This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Dubois NTMS quadrangle in Idaho and Montana. Totals of 1024 water samples and 1600 sediment samples were collected from 1669 locations in the Dubois quadrangle. Water samples were taken at streams, springs, and wells; sediment samples were collected from streams and springs.

This report describes an investigation of the effects of stream channelization on fish and macro-invertebrates in low gradient reaches of Blacksmith Fork River and the Logan River in the floodplain of Cache Valley in northern Utah. Channelization adversely affected both fish and macro-invertebrate populations and biomass, with the severity of impact directly related to the amount and duration of disturbance of the physical habitat.

From abstract: Jurassic ammonites of late Bathonian to middle Callovian Age have been found in 12,000-13,000 feet (3,660-3,960 m) of strata exposed in the area near and south of Izee and Seneca in east-central Oregon. Ammonites of early Callovian Age and possibly also late Bathonian Age occur in several hundred feet of black shale exposed along Dennett Creek near Mineral, Idaho. Early Callovian ammonites also occur in similar black shale exposed on the Oregon side of Snake River Canyon about 32 miles (52 km) south of the northeast corner of Oregon.

From purpose and scope: Purposes of this report are: (1) To define the areal distribution and occurrence of all thermal springs in the Boise River basin, (2) to evaluate their chemical and isotopic compositions, and (3) to quantify the amount of heat and water presently discharging from the springs.

From purposes of approach of study: The purposes of this study were to: (1) Define, on a reconnaissance level, current (1979) water-quality conditions in major aquifers (water-yielding rock formations) in the eastern Snake River basin; (2) present available geologic and hydrologic data to assist in understanding the natural and man-caused factors that affect water-quality conditions; and (3) establish a hydrologic base upon which future comparisons can be made to evaluate changes.

Purpose and scope: The purpose of the study was to determine whether a thin layer of volcanic ash measurably affects aquatic environments. Study objectives were to: (1) Determine the amount of ash initially deposited in Big Creek basin and the amount remaining 1 year after the eruption, and (2) describe the impact of ash on water quality and benthic invertebrate communities.

From purpose of study: In January 1980, the u.s. Environmental Protection Agency (EPA) recommended that a ground-water monitoring program for organic constituents be started at the INEL. In response to this recommendation, DOE requested the U.S. Geological Survey to undertake such a program. The purpose of the study was to determine the distribution and extent of organic constituents in the ground water beneath the INEL.

From purposes and approach of study: The primary purposes of this study were to: (1) Define, on a reconnaissance level, current (1980) water-quality conditions in major aquifers (water-yielding rock formations) in the western Snake River basin, Swan Falls to Glenns Ferry; (2) summarize and interpret available geologic and hydrologic data to assist in understanding the natural and man-cause factors that affect present and future understanding the natural and man-caused factors that affect present and future water-quality conditions; and (3) establish a hydrologic data base on which future data can be compared to evaluate changes. A secondary purpose was to evaluate the possible effects percolation of thermal water applied for irrigation may have on the quality of local, less mineralized, nonthermal ground water.

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 abstract: All geologic conditions in the Dillon Quadrangle (Montana and Idaho) have been thoroughly examined, and, using National Uranium Resource Evaluation criteria, environments are favorable for uranium deposits along fractured zones of Precambrian Y metasediments, in the McGowan Creek Formation, and in some Tertiary sedimentary basins.

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. This report is one of a series presenting data obtained by SRL reconnaissance.

Abstract: Field and laboratory data are presented for 410 water samples and 702 sediment samples from the Preston Quadrangle, Wyoming; Idaho. Uranium values have been reported by Los Alamos National Laboratory in Report GJBX-70(78). The samples were collected by Los Alamos National Laboratory; laboratory analysis and data reporting were performed by the Uranium Resource Evaluation Project at Oak Ridge, Tennessee.

From Introduction: "The Sandpoint Quadrangle (Fig. 1) was evaluated to define areas with geologic environments favorable for uranium deposits. Environments were evaluated on the basis of surface investigations because few subsurface data were available."

From Introduction: "The Spokane Quadrangle, located in parts of Washington, Idaho, and Montana between lat 47º and 48º N. and long 116º and 118º W.

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 Purpose and Scope: "The Dubois Quadrangle, Idaho and Montana (Fig. 1), was studied to identify geologic environments and delineate areas favorable for uranium deposits. These reports summarized field observations and contained preliminary evaluations of geologic environments for uranium deposition. The identification of environments favorable for uranium deposition involved collection and interpretation of radiometric, geochemical, and geologic data."
