Lac du Grand Duc Fishing in Mauricie, Quebec

• Overview

  Mauricie in Quebec is where Lac du Grand Duc sits. The setting is boreal forest. About 5 hectares of surface, which puts the far bank inside easy sight. 70 km away sits Manawan, the nearest town.

Near neighbours: Lac Pot lies 0.8 km on, 0.8 km out stands Lac Carriere, Lac Fer a Cheval lies 1.5 km on, 1.7 km out stands Lac Nicole and Lac Dumain lies 2.5 km on. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Lac du Grand Duc

  No depth figure appears in our records, so the bank has to tell you. Read the surface for the wind lane, then fish the edge of it. This is a lake, so the margins and the first drop matter most. Records held for Mauricie cover northern pike, brook trout and walleye. The list covers the county rather than this water alone, so treat it as a guide. Lac du Grand Duc gives up more to patience than to distance.

• Seasonal Patterns

  Expect July to average close to 17°C, with January the cold end at about -17°C. This is a two-season water: locked, then wide open. Ice-out usually falls in early May, and the weeks after it fish hardest. Ice usually gives way near early May, and forms again about mid November. The middle of summer slows a little, with dawn and dusk carrying it. At Lac du Grand Duc the season follows that pattern closely.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Bank access can be seasonal on ground like this. Some stretches are reserved and marked as such on the ground. Failing this one, try Lac Pot, 0.8 km away. For Lac du Grand Duc, the notice at the access point is the final word.
