During a recent field investigation, the flow of ground water was examined in the vicinity of three closed basins in glacial till in an area receiving approximately 34 inches average annual precipitation. Piezometric data indicate that during the period of study one of these basins was continually a ground‐water discharge area, whereas the others alternated between recharge and discharge. The water table rose adjacent to all three of the basins at some time during the study. Comparison of hydrographs of piezometers, precipitation data, and the level of the marshes within the closed basins indicates a variable effect of precipitation on fluid potential and marsh level. Basin area and shape influence the alternation of a given basin between recharge and discharge conditions. Water quality data suggest that all three of the basins examined have had either surface water or ground‐water outlets at some time, although not during the period of study.
