Variations of deuterium and oxygen-18 concentrations in thermal ground waters and local nonthermal springs have been used to aid in describing the source of recharge in the Bruneau-Grand View and Weiser areas, southwest Idaho. Isotope and geochemical data for the Bruneau-Grand View area suggest that recharge to the area may not be entirely from sources within the local surface-drainage area, but possibly from the areas of higher altitude of the Bruneau River drainage to the southeast; or that the hot water that wells and springs are discharging is water that was recharged at a time when the regional climate was much colder than the present climate. Recharge to the Weiser area is probably from areas of higher altitude to the north and northeast of the local drainage area. However, "local" precipitation does influence both the chemical and isotopic compositions of the waters in each area. INTRODUCTION The Bruneau-Grand View and Weiser areas (fig. 1) were recommended for geothermal investigation by Young and Mitchell (1973). Subsequently, studies of the geothermal potential of those areas were made by the U.S. Geological Survey in cooperation with the Idaho Department of Water Resources (Young and Whitehead, 1975 and 1975b). In conjunction with the above studies, water samples were collected for analyses of D (deuterium) and 18 0 (oxygen-18), which, it was believed, could aid in understanding the.hydrology of the two areas. Isotope analyses were incomplete at the time of publication of the above reports. This report contains the isotope and related chemical data for the Bruneau-Grand View and Weiser areas and summarizes the analyses of those data. The isotope data presented in this report are sparse and do not represent the entire ground-water flow system of each area, and, therefore, must be considered to be of a reconnaissance level. Additional isotope samples might provide further clues to help in describing the ground-water flow system of each area.
