The Bogen (Kazakh: Бөген Bögen, Russian: Бугунь Bugun) is a river in Baydibek and Otyrar districts, Turkistan Region, southern Kazakhstan. It has a length of 164km (102miles) with a basin area of 4680km2.
In 1967 the Bogen Dam, with an area of 65km2, was built on the river, connecting to the Syr Darya basin by means of the Arys-Turkestan Canal. The waters are used for irrigation.[1] [2]
The river begins at the confluence of the rivers Ulken Bogen and Bala Bogen, flowing from the southwestern slopes of the Karatau ridge. It flows roughly westwards through a floodplain that is between 300m (1,000feet) and 600m (2,000feet) wide. In its last stretch it bends northwards and discharges into lake Kum-Kol, not reaching the Syr Darya channel. The river is fed mainly by snow and groundwater. Its longest tributary is the 164km (102miles) long Shayan (Шаян), now flowing into the Arys-Turkestan Canal.[3] [4] [2]
