AT A GLANCE
Why go?
Lac du Corbeau is a 153-hectare lake tucked within the vast public wilderness of ZEC Bras-Coupé-Désert in Quebec's Outaouais region. Known for its strikingly clear water and pristine oligotrophic character, it sits at the heart of a 1,205 km² territory crisscrossed by rivers, waterfalls, and more than 125 lakes — a landscape shaped by the Gatineau River watershed and the legacy of the logging era.↗
Whether you come for the fishing, the paddle-in solitude, or simply the stillness of a boreal lake surrounded by low hills and forest, Lac du Corbeau rewards visitors with an authentic Quebec backcountry experience just a short drive from Maniwaki.
A Clear-Water Lake in the Boreal Shield
The science tells the story plainly: Lac du Corbeau's water quality has been formally classified as oligotrophic, meaning it is low in nutrients and remarkably clear. A Secchi disk dropped into its depths vanishes only at 4.2 metres, and phosphorus levels hover around 5 micrograms per litre — barely above pristine. Chlorophyll readings confirm minimal algal growth, giving the lake that glassy, slightly blue-green clarity that boaters and swimmers notice immediately.
The lake's surface area of 153 hectares makes it a comfortable size for a day of paddling or a morning of casting lines. The small dam at its outlet — the Barrage du Corbeau, built in 1968 — was originally used for log floating, a reminder of the forestry operations that shaped much of this territory. Today it gently regulates water levels, and its 22-metre length of wood-and-earth caissons blends almost unnoticeably into the shoreline landscape.
