# Métascouac Lake

The lac Métascouac is a fresh body of water crossed by the Métascouac River, in the unorganized territory of Lac-Jacques-Cartier, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada. Lac Métascouac is part of the Laurentides Wildlife Reserve.
The area around the lake is served indirectly by the route 169 (connecting Quebec (city) to Alma) and by the route 155 (connecting La Tuque and Chambord). A few secondary forest roads serve this area for the purposes of forestry and recreational tourism activities.
Forestry is the main economic activity in the sector; recreational tourism, second.
The surface of Lac Métascouac is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.

## Toponymy

The term “Métascouac” would a priori have been attributed to the river into which Lac Métascouac discharges. Surveyor Frederic William Blaiklock explored in 1847 the territory between Stoneham, near Quebec (city), and Métabetchouan–Lac-à-la-Croix, at Lac-Saint-Jean, with a view to the possible construction of a road connecting these two points. He identifies and describes this watercourse under the name of “Rivière Metasquiac”. The toponym appeared in 1870 in the form "Grand L. Metasquéag" on the "Map of the province of Quebec" by Eugène Taché. Surveyor Henry O'Sullivan explored the site in 1892 and described the lake as one of the most beautiful in the entire Métabetchouane river basin, dotted with green islands and bordered on each side by gently sloping hills.
Two distinct sources attributed to the Oblate missionary and philologist Georges Lemoine attribute different meanings to the toponym. The first makes “Métascouac” come from the Innu words “matau” and “iskwewak” which we translate by “lac aux belles femmes”, however, casting some doubt as to this interpretation. The second relates to it the meaning of "where there is only green wood". However, when he published his "Dictionnaire montagnais-français" in 1901, Father Lemoine himself gave the toponym the meaning of "place where three streams meet". This etymology seems the most plausible given the appearance of the surrounding places. The Métascouac River, into which the lake flows, joins in fact, some twenty kilometers below, with the Métabetchouane River. This junction is made at a right angle, in the shape of a T, so that at this precise place, one has the impression of observing three watercourses which join.
The toponym "Lac Métascouac" was formalized on December 5, 1968, by the Commission de toponymie du Québec.
