Uzboi channel

Even recently a high water level for the Aral Sea of 72-73 m a.s.l. was still accepted by some scientists, sometimes in connection with a possible overflow towards the Sarykamysh Basin and the Uzboi channel [22, 36, 37]. This high water level had already been criticized by Letolle and Mainguet [23] and can now definitely be ruled out due to the undisturbed settlements from the Upper Pleistocene discovered at heights of 55-60 m a.s.l. near Tastubek (Figs. 1, 2) on the northern shores of the Aral Sea. What the actual water level was can not be determined from archaeological data at present, but it must have been below 55 m a.s.l.
