Lake Tuz occurs. For most of the year, it is very shallow (approx.). During winter part of the salt is dissolved in the fresh water that is introduced to the lake by precipitation and surface runoff (to 324% salinity). During the summer the lake dries up exposing an average of 30 cm thick salt layer in August. This mechanism is used as a basis for the process of the salt mines in the lake. The three mines operating in the lake produce 63% of the salt consumed in Turkey. The salt mining generates industrial activity in the region, mainly related to salt
Lake Tuz Natural Gas Storage salt formation covers an area of . It is long and around thick. It has a salt dome structure. To create the caverns in the salt formation, fresh water was brought by pipeline from Hirfanlı Dam at distance. Using the process of solution mining, water was injected through a borehole into the salt formation, and the saline water, which is formed after dissolution of salt in water, was pumped back to the surface leaving a void in the formation. The salt water was transported to far away Lake Tuz by pipeline. Gas pressure inside the storage is nearly . The
