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