Starting 2019, the USGS System developed a multiscale methods technology testbed approach to monitoring groundwater discharge Neversink Reservoir watershed Catskill Mountains of New York. Groundwater dynamics complex space time because geographic variability, topography, preferential flow patterns, processes necessitates an innovative that includes emerging water tracing enhanced local geologic mapping. This fact sheet describes applied specifically how varied data types complimentary understanding groundwater-stream connectivity, with elements transferable other watersheds.
