The
Jurua is the next great southern affluent of the
Amazon river west of the
Purus, 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. It rises among the
Ucayali highlands, and is navigable and unobstructed for a distance of 1133 miles above its junction with the Amazon.
