In Mato Grosso to the south of the border with Amazonas the river defines the western boundary of the
Igarapés do Juruena State Park, created in 2002. To the north of the Amazonas border it flows through the
Aripuanã Sustainable Development Reserve, created in 2005. Further north in Amazonas the
Trans-Amazonian Highway (BR-230) crosses the Aripuanã. North of the highway the river flows through the
Aripuanã National Forest, a sustainable development unit created in 2016 in the last week before the provisional removal of president
Dilma Rousseff. It then flows through the
Juma Sustainable Development Reserve before meeting the Madeira. There are four
dams on the river (
Dardanelos Dam,
Faxinal I and
Faxinal II at Aripuanã town, and
Juína Dam west of
Juína) and a fifth is planned (
Prainha Dam on the middle Aripuanã River). These have impacted the environment and caused conflicts with
indigenous people. ==See also==
