The hydrographic slope of Cherrier Lake is accessible through a forest road (North-South direction) which passes on the east side of the Saint-Cyr River Valley; in addition, another forest road (East-West direction) serves the north of the Lac Saint-Cyr Biodiversity Reserve.

The surface of Cherrier Lake is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

This hydronym evokes the life work of Como-Séraphin Cherrier (Repentigny, 1798 - Montreal, 1885) who is recognized as a person of exceptional nature, according to the Canadian Prime Minister, Sir Wilfrid Laurier.

Having practiced as a lawyer from 1822 to 1860, he pleaded famous causes, notably that where he represented the lords in their claims for compensation, on the occasion of the abolition of the seigneurial regime in 1854.

The toponym "Lac Cherrier" was made official on December 5, 1968 by the Commission de toponymie du Québec, when it was created.
