Cuareim

The Cuareim flows west across the grasslands of the upper Uruguay basin and joins the Uruguay River. Its course drains a rolling country of streams and open plains. In the colonial period this region lay between Spanish and Portuguese claims, and cattle ranged over the grasslands of the wider Banda Oriental. The Uruguay River and its tributaries connected this interior country to the missions and settlements farther north and south.

The later city of Salto lies here.
