Tuba (river)

The Tuba (Туба́) is a river in Krasnoyarsk Krai in Siberia in Russia. It is formed by the confluence of the rivers Kazyr (Казыр) and Amyl (Амы́л) and is a right tributary of the Yenisey.

The length of the river proper is 119 km or 507 km from the headwaters of the Kazyr in the Eastern Sayan Mountains in the Minusinsk Hollow. The area of its basin, which includes more than a thousand lakes, is 36900 km2.

The Tuba flows into the Krasnoyarsk Reservoir so that the mouth of the Tuba is actually part of the reservoir.

The river is navigable at high water to 99 km from its mouth, but it freezes sometime around late October to early December, and thaws from April to early May.

There are two (sometimes considered three) road bridges and a railway bridge constructed over the Tuba.
