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