The boat called "Banzeiro" was the first to return to the municipality of Benjamin Constant, in the Upper Solimões, on the border with Peru.
Navigation in the region was restricted to large boats due to the level of the Solimões River, which suffered from this year's historic drought.
To reach the city's port, it was necessary to navigate carefully using a small boat in front to measure the river's level.
The crew of the smaller boat used measuring equipment in the Solimões channel to check its height and the route to follow.
The information was passed via radio to the captain of the "Banzeiro", who decided to continue on his journey.
The vessel that left the municipality of Tabatinga took two hours to reach the port of Benjamin Constant.
The return to the municipality was celebrated by the boat's crew.
Traders in the region are more excited about the return of supplies and the arrival of more boats with the rise of the Solimões River.
