Caroaebe RiverThe Caroaebe River is a river of Roraima state in northern Brazil, near the equator.GeographyThe headwaters are at approximately between the towns of Caroebe and São [João da Baliza], on the northern side of the connecting roadway BR-210. The river flows westward to approximately where it merges with the larger Anauá River, just prior to the Majada waterfall which is to the north of São [Luiz, Roraima|São Luiz].EcologyAlong the river, biologists have studied species of black flies which carry a parasite that causes river-blindness.
