Rouge River (Laurentides)
watercourse in Grenville-sur-la-Rouge, Quebec, Canada

This 161 kilometres (100 mi) river takes its source at Lac de la Fougère and flows south to empty into the Ottawa River near Pointe-au-Chêne and flows north of Mont Tremblant, of which it is a tributary of the left bank. It is in the Laurentides, about halfway between Ottawa and Montreal. Its name is derived from the reddish tint of its sandbanks.
The river is a popular destination for whitewater rafting. Its last 10 kilometres are renowned for rafting. It is the main body of water in an area comprising hills, valleys, lakes, and waterfalls.

Why this record matters
The phrase “watercourse in Grenville-sur-la-Rouge, 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.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q2155741. Authority coordinates are 45.643, -74.691. 1 of 2 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
