The Chulym is 1,799 km long and drains an area of 134,000 sq km. It is formed by the confluence of the Belyi Iius and Chernyi Iius rivers, which rise in the Kuznetskii Alatau. From its source to the city of Achinsk the river flows through mountains, but from Achinsk to Tegul’det it flows first between high banks and then through the Chulym-Enisei Basin, where it branches and frequently shifts course. The Chulym then flows over a floodplain up to 10 km wide, where it forms numerous lakes and oxbows; the channel, which is up to 1,200 m wide, has many branches.
The Chulym is fed primarily by snow, with high water occurring between May and July. The mean flow rate is 785 cu m per sec, with a maximum rate of 8,220 cu m per sec (131 km from the mouth) and a minimum rate of 108 cu m per sec. The river freezes over in early November, and the ice breaks up in late April or early May; ice jams often occur in the spring. The average sediment discharge is 68 kg per sec, and the river carries a sediment load of 2.1 million tons per year. The largest tributaries are the Serezh, Uriup, Kiia, and Iaia on the left and the Kemchug, Chichkaiul, and Bol’shoi Ului on the right.
The Chulym is used for floating timber. The river is navigable for a distance of 1,173 km from the mouth; however, the river bars and the twisting course make navigation difficult. The cities of Nazarovo, Achinsk, and Asino are situated on the Chulym.
