Available hydrologic and geologic information was studied using flow system theory in an attempt to delineate groundwater flow systems in Nevada with definition of sink areas, source areas and configuration of flow within the flow system as the primary objective. Source areas and configuration of flow were approximated in most areas. Sink areas have been confidently located for nearly all of the flow systems. Several types of fluid potential measurements are demonstrated to be the optimal methods of delineating groundwater flow systems. Changes in fluid potential in the vertical direction establish source areas, zones of lateral flow, sink areas and boundaries of circulation cells. Groundwater temperature was used to establish apparent depth of circulation. Characteristics of large springs in the carbonate rock province of Nevada, including water chemistry, water temperature, variation in discharge, tritium concentrations and C-14 determinations, have aided flow system delineation.
