The Kemchug ( Russian Кемчуг ; in the upper to middle reaches also Bolshoi Kemtschug, Großer Kemtschug, Большой Кемчуг ) is a 441 km long right tributary of the Chulym in the Krasnoyarsk region in Russia .
The Kemchug rises a good 40 km southwest of Divnogorsk in the extreme northwestern foothills of the Eastern Sayan , there called Kurbatowo-Syrskoje Belogorje . After a few dozen kilometers in a north-westerly direction, the river leaves the mountains and then flows through the eastern part of the Chulym Plain in a wide, flat, mostly swampy valley and increasingly meandering in a northerly direction. After the confluence of the largest right tributary, Maly Kemtschug (Kleiner Kemtschug), it turns to the northwest and after a further 100 km as the crow flies (174 km of river) it flows into the Chulym about 100 km north of Achinsk .
The catchment area of the river covers 10,300 km². The most important tributaries are the Maly Kemtschug (length 138 km) from the right and the Nikischkina (86 km), Surasowka (100 km) and Kytat (100 km) from the left.
The discharge 111 km above the mouth is an annual mean of 49.26 m³ / s, with a maximum monthly mean of 304 m³ / s in May and a minimum monthly mean of 5.24 m³ / s in March. The river freezes over from October / November to April / early May.
Because of the mostly swampy banks, there are only a few small towns directly on the river. Not far from the source, the M54 highway runs from Krasnoyarsk via Abakan to the Mongolian border. The upper course of the river crosses the Trans-Siberian Railway and follows its right (eastern) bank at the stations of Kosachi to Kemchug (about 3995-4004 km from Moscow ). A few kilometers to the north the river crosses the M53 Novosibirsk - Irkutsk road . The middle reaches of the Kemtschug crosses near the urban-type settlement Rassvet the railway line Achinsk - Lessosibirsk .
