Igapó-Açu River

The Igapó-Açu River is a river located in the Amazonas state in northwestern Brazil. It flows as a left tributary of the larger Madeira River, which is an important part of the Amazon's water system.

This river moves through the Purus-Madeira moist forests ecoregion, a rich and green area full of different plants and animals that depend on the river for their home. The Igapó-Açu River helps support this special environment and connects many parts of the Amazon.
