Lac Dernier in Mauricie: How and When to Fish It

• Overview

  Lac Dernier lies within the bounds of Mauricie, Quebec. It lies 478 metres above sea level. Roughly 18 hectares: a morning covers one end, an afternoon the other. The whole outline is near 2.1 km, and most of it is walkable. The nearest place of any size is Weymontachie, 42 km away. Leblanc is 67 km and Saint-Félicien 89 km. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Lac Dernier

  Nothing we hold settles how deep this runs. Read the surface for the wind lane, then fish the edge of it. Look for the band where the shallows give up and the bottom falls away. Public occurrence data for Mauricie names northern pike, brook trout, walleye, yellow perch and white sucker. These are county-wide records, so not all of them will be in this water. Lac Dernier fishes better once you know its edges.

• Seasonal Patterns

  The warm month here averages 16°C; the cold one sits at -18°C. This far north the hard season runs and runs. Winter locks it down, and early May brings it back. In an average year the thaw lands around early May and the freeze near mid November. Just after the ice goes and just before it returns, the fishing lifts. At Lac Dernier the season follows that pattern closely.

• Tackle & Baits

  Whether you may fish here is not something records settle. It formed naturally, so levels move with rainfall rather than with a gate. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. A small crankbait along the drop and a worm in the thick stuff cover the bass. Sort the permit out before you load the car. Some water is controlled locally without a sign saying so. Failing this one, try Lac Bazou, 1.4 km away. The position on Lac Dernier is worth confirming on the day.
