A bridge spans the river at the village of Waswanipi.
From its source, the course of the river flows over 139.4 kilometres (86.6 mi) distributed as follows:

Main tributaries
[edit]Toponymy
[edit]As early as the 18th century, the designation "Waswanipi" means a lake Waswanipi, two rivers, and a Native American group. The river has already been referred to as the "Olga River". A map of 1898 indicates "R. Waswanipi" for this watercourse. At the beginning of the 20th century, during a voyage of exploration in northern Quebec, geologist and land surveyor Henry O'Sullivan borrowed this waterway.[2]
The toponym Waswanipi River was formalized on December 5, 1968, at the Commission de toponymie du Quebec.[3]
