Juruá

The Juruá River is a southern affluent of the Amazon River, west of the Purus River, that shares the bottom of the vast inland Amazon depression with the Purus and shares all of the Purus' characteristics in terms of curvature, sluggishness, and general characteristics of the low, half-flooded forest country it traverses.

The river flows in the Purus várzea ecoregion for the majority of its length. The Juruá-Purus damp woods ecoregion surrounds it. It rises in the Ucayali highlands and is navigable and uninterrupted for 1,133 kilometers above the Amazon River's confluence. It is one of the Amazon's longest tributaries, with a total length of around 1,500 miles.

The Médio Juruá Extractive Reserve, which was established in 1997, is located on the left bank of the river as it meanders northeast through the municipality of Carauari. The western boundary of the 187,982 hectares Baixo Juruá Extractive Reserve, established in 2001, is formed by the lower Juruá River. The lower section of the river in Brazil has been recognized as a Ramsar site since 2018.

Total Length: 1,926 miles (shared with Brazil)
