Course

The Maracanã is a meandering river with a main channel that varies in depth in its lower reaches from 15 to 20 metres (49 to 66 ft).[1] It rises in the south of the municipality of Castanhal, Pará, then flows in a northeast direction to the Atlantic Ocean at Maracanã, Pará.[2] The river is lowest between September and October and highest between February and April. Its main tributary is the Caripi River, which enters the Maracanã from the left.[1]

Santarém Novo is on the right bank of the river about 35 kilometres (22 mi) from its mouth on the Atlantic.[3] The Chocoaré - Mato Grosso Extractive Reserve protects part of the right (east) shore of the Maracanã River.[4] The lower reaches of the Maracanã River, before it empties into the Atlantic Ocean beside Maiandeua Island, are protected by the 30,179 hectares (74,570 acres) Maracanã Marine Extractive Reserve, created in 2002. The municipality and town of Maracanã are at the mouth of the river.[2]
