Lac du Grand Duc, Quebec: Fishing Spots and Seasons

It lies deep inside the county rather than near an edge.

• Where to Fish on Lac du Grand Duc

  No depth figure has reached our records, which makes a plummet useful. On a natural lake the weed line and the shelf beyond it do the work. A soft bed grows weed late into autumn, which keeps fish shallow. Reported across Saguenay/Lac-Saint-Jean: northern pike, Atlantic salmon, lake whitefish and fallfish. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. The shape of Lac du Grand Duc rewards a slow walk along one bank.

• Seasonal Patterns

  Long-run averages give July about 16°C and January about -18°C. Water stays cold even at the height of the year. Winter locks it down, and early May brings it back. On the long-run averages the water opens up around early May and starts locking again about mid November. The middle of summer slows a little, with dawn and dusk carrying it. Keep it in mind when planning a trip to Lac du Grand Duc.

• Tackle & Baits

  Whether the bank is open is not something our records settle. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. For the pike, wire up and throw larger lures along the weed edges. Ask in the nearest town if you are unsure. Signs go up and come down, so check on the day. Failing this one, try Lac Gabriel-Fleury, 1.1 km away. Ask locally about Lac du Grand Duc if anything is unclear.
