Canumã River
Canumã River is a river in the Amazonas state in north-western Brazil. It is located east of the Madeira River and runs roughly parallel to it. It flows into the Paraná Urariá shortly before merging into the Madeira River. Through the Paraná Urariá it is also connected to several other smaller rivers and ultimately Paraná do Ramos, which is a side channel of the Amazon River itself. The Canumã has its source at the confluence of the Acari and Sucunduri Rivers. The latter and Canumã can be considered as the upper and lower sections of a single river, in which case it is known as the Canumã-Sucunduri.
