McSweeney Lake
part of the Gouin Reservoir, in La Tuque, Mauricie, Quebec, Canada
The Lake McSweeney is a freshwater body located in the Center-East part of Gouin Reservoir, in the territory of the town of La Tuque, in the administrative region of the Mauricie, in the province of Quebec, in Canada.
This lake in the middle of the Center-East part of the Gouin reservoir straddles the townships of McSweeney, Magnan, Marmette and Brochu.
Recreational tourism activities constitute the main economic activity of the sector because of its strategic position for navigation, being located between Marmette Lake, Magnan Lake and Nevers.
The hydrographic slope of Lake McSweeney is served indirectly on the north side by route 212 connecting the village of Obedjiwan to the east shore of the Gouin Reservoir; this road provides access to Toussaint Lake and to the various bays on the northeast shore of the Gouin Reservoir. A few secondary forest roads have been built on the North-North shore of the Gouin Reservoir for logging and recreational activities.
The surface of McSweeney Lake is usually frozen from mid-November to the end of April, however safe traffic on the ice is generally from the beginning of December to the end of March. Water management at the Gouin dam can cause significant variations in the water level, particularly at the end of winter when the water is lowered in anticipation of the spring melt.
Geography
Before the construction of La Loutre Dam was completed in 1916, thus creating Gouin Reservoir, lake McSweeney had a smaller dimension. After the second raising of the waters of the Gouin reservoir in 1948 due to the development of the Gouin Dam, Lake McSweeney took on its current form.

Why this record matters
The phrase “part of the Gouin Reservoir, in La Tuque, Mauricie, Quebec, Canada” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q22632488. Authority coordinates are 48.643, -74.770. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1916 and 1948.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
