Juruá River
River in Brazil, Peru
From Wikipedia, the free encyclopedia
The Juruá River (Portuguese: Rio Juruá [ʒuɾuˈa]; Spanish: Río Yuruá) is a southern affluent river of the Amazon River west of the Purus River. The Juruá emerges from highlands in east-central Peru, then winds its way through lowlands in Brazil, sharing with this the bottom of the immense inland Amazon depression; and having all the characteristics of the Purus as regards curvature, sluggishness and general features of the low, half-flooded forest country it traverses.

For most of its length, the river flows through the Purus várzea ecoregion.[6] This is surrounded by the Juruá-Purus moist forests ecoregion.[7] The Juruá rises among the Ucayali highlands, and is navigable and unobstructed for a distance of 1,133 km (704 mi) above its junction with the Amazon. It has a total length of approximately 3,283 km (2,040 mi), and is one of the longest tributaries of the Amazon.
The 251,577-hectare (621,660-acre) Médio Juruá Extractive Reserve, created in 1997, is on the left bank of the river as it meanders in a generally northeast direction through the municipality of Carauari.[8] The lower Juruá River forms the western boundary of the 187,982 hectares (464,510 acres) Baixo Juruá Extractive Reserve, created in 2001.[9] Since 2018, the lower portion of the river in Brazil has been designated a protected Ramsar site.[10]
