Toponymy

This toponym was recorded around 1930 in a topographic survey of the region by the surveyor J.-M. Roy. Presumably of Cree origin, this toponym could mean "it is a pass, a narrow passage, on the water, between two elevations of ground".[2]

The toponym "Lake Opataca" was formalized on December 5, 1968 by the Commission de toponymie du Québec, when it was created.[3]
