A narrow spit separates it from the eastern shore of the Sea of Azov. It used to be an inlet of the sea and was connected to the Baisug Lagoon. The lake is about 12 times saltier than the neighbouring sea. In a hot summer the lake dries up exposing large deposits of mud which may be used for balneological purposes. Legend has it that one khan of Crimea liked to bathe in the lake's healing waters, hence the name.
