Cuminapanema River
The Cuminapanema River is a river of Pará state in north-central Brazil, a tributary of the Curuá River. The river basin lies partly within the Grão-Pará Ecological Station, the largest fully protected tropical forest conservation unit on the planet. It flows through the Trombetas State Forest from north to south. Part of the river's basin is in the Maicuru Biological Reserve. The river is also fed by streams in the Mulata National Forest, a sustainable use conservation unit created in 2001.
