The Tundik (Kazakh: Түндік; Russian: Тундик) is a river in the Karkaraly District, Karaganda Region, and Bayanaul and May districts, Pavlodar Region, Kazakhstan. It is long and has a catchment area of .
The river is fed mainly by snow and underground water. It is frozen between November and April. The Tundik waters are used to irrigate the agricultural fields and pastures of the settlements near its banks.
The Tundik has its sources near Akkora, on the slopes of the Keshubai and Konyrtemirshi mountains of the Kazakh Uplands. It heads roughly northwards, bending northeastwards by Mount Ku. After leaving the mountain to the west it flows northwards again. Shortly before reaching the 51st parallel north the Tundik bends northeastwards. Finally it reaches salt lake Karasor and enters it from the western shore.[1] [2]
The width of the river valley in the upper course is between 0.2km (00.1miles) and 0.3km (00.2miles), in the middle stretch between 1km (01miles) and 2km (01miles), and in the lower reaches of the river the valley widens, reaching 7km (04miles) to 10km (10miles). The riverbanks are mostly steep, between 1m (03feet) and 2m (07feet).[3]
The main tributaries of the Tundik are the 67km (42miles) long Bala Tundik, with its sources in Mount Ku, on the left, and 78km (48miles) long Ashchyshiozek on the right. Other major tributaries are 48km (30miles) long Kyzylashchy, 37km (23miles) long Akzharyk, 30km (20miles) long Upper Karasu, 35km (22miles) long Lower Karasu, 21km (13miles) long Sarybulak, 21km (13miles) long Egindibulak, 17km (11miles) long Zharkayin and 10km (10miles) long Kundik .[3] [1]
