The river originates in the Coxilha de Santana, an area of low-lying hills, and runs westward to join the Uruguay River. It forms the boundary between Uruguay on the south and Rio Grande do Sul state of Brazil on the north.There is a long-standing and unresolved border dispute between Uruguay and Brazil along part of Quaraí River.
