The Barnaulka (Russian: Барнаулка) is a river in Altai Krai, Russia. The river is 207 kilometres (129 mi) long and has a catchment area of 5,720 square kilometres (2,210 sq mi).^[1]

The basin of the river is located in the Rebrikhinsky, Shipunovsky and Pavlovsky districts. The city of Barnaul is named after the river.^[2] The Barnaulka suffers from the impact of pollutants released by industrial activity along its course.^[3]

Course

The Barnaulka is a left tributary of the Ob river. It has its sources in Zerkalnoye, a lake with a 18 square kilometres (6.9 sq mi) surface lying 60 km (37 mi) to the west of Aleysk. The upper course of the river is a chain of lakes connected by marshy canals located in the Ob Plateau (Приобское плато). There are numerous swamps and smaller lakes in its basin. The Barnaulka flows in a roughly northeastern direction. Finally it meets the left bank of the Ob at Barnaul, 3,409 km (2,118 mi) from the Ob's mouth.^[4]

Tributaries

The longest tributary of the Barnaulka is the 18 km (11 mi) long Vlasikha (Власиха) on the left. The river is largely fed by groundwater. It is frozen between November and April.^[1][5]
