  ABSTRACT: Gravity, ground magnetic, end terrain conductivity surveys were
            run in Washoe Valley to define subsurface lithology for input to
            a groundwater model The gravity results map basin configuration,
            with a shallower basement on the east indicated. High magnetic
            end terrain conductivity values reflect a volcanic unit
            overlying this shallow eastern basement, which is in turn
            overlain by electrically conductive fine-grained sediments.
            Together, these units suggest much lower transmissivities on the
            east side of the valley, relative to a thicker section of coarse-
            grained sediments to the west. These low transmissivities are
            required by the groundwater model to fit the 1965 potentiometric
            surface to which the model is calibrated. This study
            demonstrates the utility of combining the results of multiple
            geophysical surveys with conventional hydrological parameters.
            This integration is particularly useful for mapping spatial
            distributions of interbasin hydraulic properties, end it
            provides excellent constraints the groundwater model.
