Groundwater hydrology was monitored from October through August in and around a bottomland forest pond containing Lindera melissifolia, pondberry. The study site exhibited a series of low ancient dunes and depressions, with seasonal ponds in the depressions. Ponds showed no surface inlets or outlets. Shallow wells were made and soil cores removed along a transect from the top of one dune across the pond to a lower dune. Piezometers were installed in the wells and groundwater levels monitored. Soil core samples were analyzed to determine particle size distribution at soil profile positions selected during field analysis. It was shown that a subsurface hydrologic gradient exists between surrounding dune slopes and the pond bottom, delivering groundwater to the pond during the season when precipitation exceeds evapotranspiration. The hydrologic gradient was shown to be substrate-dependent.
