Toponymy This hydronym uses the same name as the township of Blaiklock. This term evokes the memory of Frederic William Blaiklock (1822-1901), surveyor, native of Quebec (city). He was the first to conduct topographic measurements in the valley of the Ashuapmushuan River which is located north of Lac Saint-Jean. He also mapped out the two provincial roads leading to Lac Saint-Jean, via Stoneham and via La Tuque. From 1850 to 1853, he surveyed the territorial boundaries between Canada and New Brunswick. For 23 years (1878-1901), he was in charge of the Cadastre Office at Montreal. The Geography Commission, the current Commission de toponymie du Québec, approved this place name in 1953. The toponym "Blaiklock River" was made official on December 5, 1968, at the Commission de toponymie du Québec, that is to say, the foundation of this commission.
