Records of water levels in limesink ponds in southwestern Georgia and of water‐table levels in the vicinity of these ponds are used to demonstrate: (1) some ponds with highly impermeable beds are virtually unaffected by water‐table levels, except when water‐table levels are above the rim of the impervious materials; (2) interchange of water between pond and water table occurs when beds are relatively permeable. Three phases in the relation between pond level and water‐table level are recognized: (1) water‐table level higher than pond level causing ground‐water flow into the pond; (2) ground‐water level below pond level but in direct contact with it and measurably controlling rate of seepage from the pond; (3) ground‐water level below pond level but not in direct contact with it and not appreciably controlling rate of seepage from the pond. In phase (3) the water table has a perceptible mound at a point underneath the pond.
