Yi

The Yí flows west through the rolling grasslands of central Uruguay to join the Río Negro. Rising near Cerro Chato, it is a major tributary of the Negro’s left bank and belongs to the wider Uruguay River basin. Woodland follows stretches of its banks amid the open country. The river and its tributaries run through territory associated with Indigenous peoples of the Río Negro basin, including the Charrúa.

The later city of Durazno lies here.
