Techa

The Techa is an eastward river on the eastern flank of the southern Ural Mountains noted for its nuclear contamination. It is 243 kilometres (151 mi) long, and its basin covers 7,600 square kilometres (2,900 mi2). It begins by the once-secret nuclear processing town of Ozyorsk about 80 kilometres (50 mi) northwest of Chelyabinsk and flows east then northeast to the small town of Dalmatovo to flow into the mid-part of the Iset, a tributary of the Tobol. Its basin is close to and north of the Miass, longer than these rivers apart from the Tobol.
