This study aims to investigate the interaction between Lake Girdev and ground water in the allochthonous limestones which crop out in the area between Lake Girdev and Kazanpinari spring. In particular, the flow direction and velocity of ground water, its relationship with Lake Girdev and the effect of lithological and structural features on the ground water circulation were analyzed. The apparent ground water flow velocity was found to be 31 mh-1 using the fluorescein tracer. The ground water flows in ENE direction. Tritium and Oxygen-18 isotope data suggest that the water of Lake Girdev and ground water are likely to be of the same age and the water sinking in Lake Girdev recharges the aquifer without any change in its composition. The rainfall belt in the Elmalt Polje falls on a zone between the Eastern Mediterranean and Central Anatolia regions. It is interpreted that the allochthonuos limestone aquifer has been developed as a result of the jointed, faulted and thrusted nature of limestones.
