The Chumysh (Russian: Чумыш) is a river in Russia, a right branch of the Ob River.[1] It enters the Ob 88 kilometres (55 mi) downriver from Barnaul. The Chumysh begins at the confluence of the Kara-Chumysh and the Tom-Chumysh rivers in Kemerovo Oblast. The Chumysh is 644 kilometres (400 mi) long, and it drains a basin of 23,900 square kilometres (9,200 sq mi).[2]
About 68 percent of its right-side basin is known as the Salair Ridge (Russian: Салаирский кряж) and the Pre-Salair plains.
