Small Forest Stream, Huallaga River Floodplain, Peru
Peru, Loreto, Yurimaguas
The Huallaga River is a tributary of the Marañón River, part of the Amazon Basin. Old names for this river include Guallaga and Rio de los Motilones.
The Huallaga is born on the slopes of the Andes in central Peru and joins the Marañón before the latter reaches the Ucayali River to form the Amazon.
Its main affluents are the Monzón, Mayo, Biabo, Abiseo and Tocache rivers. Coca is grown in most of those valleys, which are also exposed to periodic floods.

Although it runs for 700 miles (1,100 km), it remains unnavigable for most part.[2] For nearly its entire length the Huallaga is an impetuous torrent running through a succession of gorges.
It has forty-two rapids (pongos) and it crosses the Andes, forming the Pongo de Aguirre gorge. From this point, 140 miles (230 km) from the Amazon, the Huallaga can be ascended by larger river boats (lanchas) to the port city of Yurimaguas, Loreto.
Although there are no defined boundaries, the river is commonly divided into two or three sections. From the town of Tocache in San Martin to the source of the river is generally referred to as the Upper Huallaga.
Regions of the river are also referred to as central Huallaga (usually from Tocache or Juanjui to Chazuta), and the lower Huallaga (usually from Chazuta to Yurimaguas where the Huallaga meets the Marañon).
These divisions are for general reference, and are independent of the “highland” and “lowland” jungle regions of the Amazon Rainforest.
- Underwater landscape
The Huallaga River flows relatively above 1000 meters above sea level. Forest streams are covered with a layer of white sand that is poor in minerals.
Small streams feature blackwater. It is a weak area in terms of aquatic flora. There are abundant stranded driftwood, wood and leaf deposits on the

- Threats to ecology
The river and the riversides suffer point source pollution, utilized as an interminable garbage dump. At least one chute for garbage trucks is installed.
The Huallaga River supports a myriad of wildlife and vegetation. The river is especially rich in amphibian life. A total of 18 species of frogs have been recorded from it, including the Prostherapis femoralis, Phyllodromus pulchellus and Dendrobates reticulatus.
