Centerline of river channels.

Centerline of rivers upstream of the Cachoeira Caldeirão Dam. A total of 260 km of rivers, obtained from GPS tracklogs recorded during boat surveys along the rivers. Rivers were divided into 52 sections at approximately 5 km intervals. Used to develop before-after control-impact analysis of dam impacts on species including Giant Otters (https://doi.org/10.7717/peerj.14287) and Yellow-spotted River Turtles ( https://doi.org/10.1002/aqc.3775).
