Tokantins Pool

It originates from the confluence of the Maranhão and Almas rivers, the source of which is on the eastern slopes of the Serra Dorada mountains, in the central part of the Brazilian Highlands . Until the Amazonian lowland flows through mountainous terrain, forming numerous rapids, including the rapids of Guarib. After reaching the plain, it becomes navigable (350 km from the mouth), is distributed and slows down after merging with the large influx (on the left) of Araguay . It falls into a pair , forming a wide estuary .

The river is fed with rain, during high water periods (from October to March-April) water rises by 7–9 m. The average discharge at the mouth is 16,300 m³ / s. ^[1] The Tokantis-Araguaya rivers are often referred to the Amazon basin, although formally they form a separate river system with an area of ​​770 thousand km² ^[1] (or more than 800 thousand km² ^[2] ).

The river is actively used for hydropower production; for 2016, the hydropower cascade includes at least five dams, including Tukurui and Serra da Mesa . The development of the cascade also pursues the goal of developing navigation on the river; in 2010, a two-chamber lock system was put into operation on Tukurui, which made it possible to expand shipping upstream of the river by a 200 km section of the reservoir of this hydroelectric complex. ^[2]
