This last road comes from Chibougamau, going north-east along the shoreline. Southeast of Waconichi Lake and the river of the same name.
The surface of the "Blaiklock River" is usually frozen from early November to mid-May, however safe ice traffic is generally from mid-November to mid-April.

The Blaiklock River originates from a forest stream in Cherisy Township. This source is located at:

north-east of the mouth of the Blaiklock River ;
east of the mouth of the Nottaway River.

From its source, the Blaiklock River flows over generally to the southwest, according to the following segments:

easterly entering the Albanel, Mistassini and Waconichi Lakes Wildlife Sanctuary, then in the township of Beaulieu, to a bend of the river;
eastward southward into Blaiklock Township, then southeasterly to the bridge of a forest road, corresponding to the boundary of the townships of Beaulieu and Blaiklock;
south-east to its mouth. Note: A forest road follows this segment.

The Blaiklock River flows on the north shore of the Barlow River (Chibougamau River). The latter flows southwest and flows into a river bend on the north shore of the Chibougamau River in a marsh area upstream of Chevrillon Lake. From there, the current flows towards the South-West by borrowing the Chibougamau River, until its confluence with the Opawica River. From this confluence, the current flows generally southwesterly through the Waswanipi River to the east shore of Goéland Lake (Waswanipi River). The latter is crossed to the northwest by the Waswanipi River which is a tributary of Matagami Lake.

Toponymy

This hydronym uses the same name as the township of Blaiklock. This term evokes the memory of Frederic William Blaiklock, 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, 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.
