Aramá River

The Aramá River is a river of Marajó, which itself is an island in the mouth of the Amazon. It is a right tributary of the Jacaré Grande River. The name Aramá stems from the Tupi–Guarani languages, meaning "Mother of Honey", referring to bees.

Course

The main source of the Aramá's waters is in the swamp areas called mondongos that are normally flooded during the wet season. The river branches off the Anajás River at its right, running along the border of São Sebastião da Boa Vista and Curralinho municipalities. Its main tributaries are the Mapuá River, the Furo Japicháua, the Braço do Soco and Braço do Jacaré. Braço do Soco is fed by a lake called Lago dos Leões on the boundary of Anajás municipality.
Water levels in the Aramá depend on the variation between rainy and dry seasons, and on the tides in the Amazon. Levels are high in the months January–June, and low from July to November.
In the past, important economic activities along the river were the extraction of rubber and logging. In the present day, the main activities are the extraction of açaí, fishery and small-scale agriculture.
The river forms the northern boundary in the western part of the Mapuá Extractive Reserve.
The Mapuá River, a left tributary of the Aramá, runs along the southern boundary of the reserve.
The reserve contains sheets of tidal water and mangroves.
The reserve is mostly lowland floodplain, with some terra firma in the centre of the territory.
