Mutuacá River

The Mutuacá River is a river of Marajó, which itself is an island in the mouth of the Amazon. It is located in the state Pará in northern Brazil, and is a tributary to the Pará River.
The Mutuacá has its source in the flooded igapó forests on Marajó Island. It flows in south-eastern direction, entering the Pará River in a bay called Baía das Bocas. Two river channels called furos connect the Mutuacá to the Guajará River. They surround an area that is called Mutuacá Island.
The river runs through part of the Terra Grande-Pracuúba Extractive Reserve, a sustainable use conservation unit created in 2006.
