The Tortum Çayı is a left tributary of the Oltu Çayı in eastern Turkey .
The Tortum Çayı rises in the mountains southeast of the city of Tortum . The river flows mainly in a northerly direction. It passes the city of Tortum and Uzundere, 30 km further north . The national road D950 follows the course of the river. After another 10 kilometers, the Tortum Çayı flows into the southern end of the Tortum Gölü ( Tortum Lake ), an originally natural lake, the water level of which was raised by 1.5 m by a dam at the northern end of the lake. The water is fed to a hydroelectric power station via canals. In the wettest months, part of the water flows in the old river bed and falls down the 48 m high Tortum waterfall . In the lower reaches of the Tortum Çayı flows through a deep gorge and after about 15 km reaches the Oltu Çayı, which flows westwards. The Çayı Tortum has a length of 112 km. It drains an area of 2100 km².
