For the Indonesian island, see Sumatra.The Pastaza River (Spanish: R\u00edo Pastaza, formerly known as the Sumatara[6]) is a large tributary to the Mara\u00f1\u00f3n River in the northwestern Amazon Basin of South America.[7]It has its headwaters in the Ecuadorian province of Cotapaxi, flowing off the northwestern slopes of the volcano Cotopaxi and known as the Patate River. The Patate flows south and in Tungurahua Province it is joined by the Chambo River just upstream from the town of Ba\u00f1os de Agua Santa just north of the volcano Mount Tungurahua and becomes the Pastaza.[8][9] Seven kilometers east of Ba\u00f1os, it is dammed for the Agoy\u00e1n hydroelectric project, which has created a silty lagoon by the village of La Cieniga.[9] The Agoy\u00e1n dam was placed in that location specifically to leave the famous Falls of Agoy\u00e1n, about 5\u00a0km further downstream, intact.  After the waterfall the river enters a gorge where there is very fast whitewater with class-4 rapids; it is often used for whitewater rafting although it is not considered to be of the same quality as the Tena River and is therefore less popular for the sport.[10]From the junction with the Chambo, the Pastaza flows almost due east for about 275 kilometres (171\u00a0mi) where it then turns south-east, as it is joined by the Topo River.[11] The Troncal Amazonas highway parallels the river from Ba\u00f1os to Puyo, passing through seven tunnels, and four major waterfalls that are touristic destinations for many Ecuadorians (Agoy\u00e1n and Pail\u00f3n del Diablo being the most popular.)  Just past the town of Santa Inez, the Pastaza River crosses into the province of Pastaza, where it forms the boundary between that province and Morona-Santiago. At the town of Mera, shortly before reaching Puyo, the river exits the mountains and flows into a wide valley, becoming wider and shallower.[12] After Shell the river becomes braided and meanders, leaving oxbows and sloughs along its route across the Amazonian floodplain.After cutting through Ecuador, the Pastaza passes into Peru at the village of Hito Zoilaluz on Isla Zoilaluz[13] and flows south into the Mara\u00f1\u00f3n River near Puerto Industrial.[2]Table of ContentsTributaries[edit]Economy[edit]Bridges[edit]See also[edit]References and notes[edit]Tributaries[edit]The Pastaza has numerous tributaries, both above and below the hydroelectric dam.  These contribute to its rapid flow and to its tendency to flood.  On the highway side of the Pastaza, a tributary river occurs about every 3\u20134\u00a0km for a stretch of about 50\u00a0km; on the opposite bank, the number of tributaries is slightly lower. The major tributaries are the Chambo, Bobonaza, and Huasaga,[7] also important are the Ambato, the Pindo, and the Puyo.Economy[edit]  Bridge over the Pastaza River between Puyo and MacasThere are no major fisheries on the Pastaza River – it is primarily used as a means of transport by canoe.[6]   Its rise and fall are rapid and uncertain, and it is shallow and full of sandbanks and snags.[14]  Flooding occurs seasonally.[6]Bridges[edit]In Ecuador, there are very few bridges across the Pastaza.  The most significant ones are in Tungurahua province – namely a large span over the exact point of headwaters, just north of Ba\u00f1os, and the secondary span created by the Agoy\u00e1n dam.  After this, bridges tend to be of the suspension type, suitable for foot or small vehicle passage only.  However, it is notable that the Pastaza can be forded during the dry season in a 4×4 truck, going across the floodplains below the town of Mera.See also[edit]References and notes[edit]^ a b Ziesler, R.; Ardizzone, G.D.
