The Aguarico River is a river in northern Ecuador. It is the main river of the Sucumbios province. In the last part of its course it is the Ecuadorian-Peruvian border. It empties into the Napo River. It has a length of 390 kilometers, of which the last 50 kilometers of its course extend along the natural border between Ecuador and Peru (in the department of Loreto). The lower course of the Aguarico river was finalized and legally fixed as part of the long-disputed Ecuador-Peru frontier according to The Rio de Janeiro Protocol of 1942. Ecuador unilaterally denounced the protocol in 1960, however a new agreement was signed in 1999 validating the pre-existing protocol .
The Aguarico river is a river that flows almost completely by the province of Sucumbios, in the north of Ecuador, being the main river of the province. In its average course it flows closely near the Reserve of Production Faunistica Cuyabeno. In the last part of its course it flows near the Ecuadorian-Peruvian border. Finally it ends at the Napo river, in the same border, a little over the locality the town of Pantoja in Loreto.
In 1541, Gonzalo Pizarro and Francisco de Orellana constructed a sailboat, the San Pedro, and followed the courses of the Colca River and the Napo river until the confluence of this one with the Aguarico river and the Curaray River, where they lacked the proper amount of provisions and supplies, including food. Several men did not survive, and it is estimated that 140 of 220 Spaniards and 3,000 of the 4,000 Indians who composed the expedition were amongst this number. They decided then (22 of February of 1542) that Orellana continued down the Aguarico river in search of food. They accompanied about fifty men to go with him. Incapable to overcome the river, Orellana waited for Pizarro. Finally Pizarro sent three men with a message to Orellana for him to begin the construction of a new boat, the Victoria. Meanwhile, Pizarro had returned towards Quito by another route towards the north, with only 80 men, those of which that remained alive.
In the highest part of the Aguarico river live the indigenous Sioni. The Siona peoples belong to the Western linguistic family tukano and their official languages are the Piohe (or Pioche) dialects and Spanish as well as a mergence between them (this mergence is sometimes called Pioche-Sione). At present they are a group of approximately 172 people reunited in 51 families. Their economic activities are based mainly on hunting, fishing and sometimes tourism. Some of the problems that the community must face in the present era are environmental contamination and the over-exploitation of lumber.
