In this study, surface waters and groundwater interactions were investigated at the Attepe-Elmadağ-Menteş-Karaçat iron fields. The study area takes place in the Menteş upper watershed and the nearby surroundings, which is located in the Seyhan River main basin. The study area is composed of the metamorphic metacarbonates and metaclastics, which were subjected to low grade metamorphism in the Precambrian-Ordovician age range. Miocene conglomerates and current alluviums overlie them with angular unconformity. In the region where the basin is located, the metacarbonates (recrystallized limestone and dolomites) which are highly fractured, cracked and in some places have dominantly karstic structure, have been identified as the main aquifer. The Menteş Stream forms the natural groundwater discharge route and the erosion level of karstification of the aquifer. The faults prevent the continuity of the karstic aquifer by determining the lateral and vertical positions of other impermeable units. It has been shown that groundwater, recharged with diffuse infiltration by precipitation and a large amount of point infiltration from the Menteş creek, is shallow circulated young water with a short residence time of 5-10 years. It is determined that a large part of the Menteş Creek (150-1000 L/s at dry and wet seasons, respectively) disappeared and added to the Karaçat aquifer. The average flow rate of the Menteş stream was calculated as 474 L/s at the eastern lower basin exit. The Karaçat aquifer, which also includes Karaçat underground mine quarry, is recharged from the Menteş Creek rather than neighboring basins. Hydrogeological investigations and isotope data confirmed the previous work result that there is no flow relation between Attepe lake and Karaçat aquifer.
