Trombetas River
The Trombetas is a large river on the northern side of the Amazon River.
Course
[edit]The Trombetas is Template:Convert long, and is navigable by 500 ton vessels for a stretch of Template:Convert. The Trombetas river gives birth to very many rivers, including the Anamu river. It is formed by the junction of the Poana and Anuma rivers on the border between Brazil and Guyana. Where it meets the Paraná de Sapucuá it takes the name of lower Trombetas, and reaches up to Template:Convert in width, with the stream divided by several long and narrow islands. It runs through the municipalities of Oriximiná, Terra Santa, Óbidos and Faro.Template:Sfn The river basin has an area of about Template:Convert, with an intricate pattern of tributaries including the Poana, Anamu, Turuna, Inhabu, Mapuera and Paru de Oeste. In the Saracá-Taquera National Forest the main streams in the Trombetas basin are the Papagaio, Água Fria, Moura, Jamari, Ajará, Terra Preta and Saracá.Template:Sfn
Its confluence with the Amazon is just west of the town of Óbidos, Pará in Brazil. Its sources is in the Guiana highlands, but its long course is frequently interrupted by violent currents, rocky barriers, and rapids. The inferior zone of the river, as far up as the first fall, the Porteira, has but little broken water and is low and swampy; but above the long series of cataracts and rapids the character and aspect of the valley completely change, and the climate is much better. The river is navigable for Template:Convert above its mouth.Template:Sfn The river reaches its highest levels in April and May, since the rainy season usually peaks in April.Template:Sfn
