River transport is also notable in the state, as well as in other states in the [[Amazon rainforest]]. However, river navigation is limited to the [[Branco River]].<ref>{{Cite web|title=Roraima (RR) - BrasilChannel.com.br|url=https://www.brasilchannel.com.br/estados/index.asp?nome=Roraima&area=quadro-natural|access-date=2021-05-02|website=www.brasilchannel.com.br}}</ref> Transportation on the Branco River is heavily used for the economy, but with little passenger movement to inland cities. Regular navigation on this river occurs only in the mouth section (Negro River/Caracaraí), about {{convert|440|km|-2|abbr=out}} long. In this segment, the Branco River has a maximum draft of 5 metres in the period of floods and a minimum of 0.7 metres in the period of drought. Roraima is at a disadvantage in relation to the other Amazonian states in terms of waterway system. As it is the only one in which all its notorious rivers have their source in their own territory – the state's hydrographic system is 100% Roraiman –, it is bound to have few river outlets. In fact, Roraima has only one major fluvial outlet: through the Branco river, reaching the Negro river, heading from there to [[Manaus]] and [[São Gabriel da Cachoeira]]. Even so, the most important river in Roraima still poses additional difficulties.<ref name=":27" />
