Maicuru River

The Maicuru River is a river of Pará state in north-central Brazil, a tributary of the Amazon that discharges into that river via the Lago Grande de [Monte Alegre].
The river basin lies partly within the Grão-Pará Ecological Station, the largest fully protected tropical forest conservation unit on the planet.
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.
