Lac Mathieu, Quebec: Fishing Spots and Seasons

• Overview

  Lac Mathieu lies in Saguenay/Lac-Saint-Jean, Quebec. The bank is 304 metres above sea level. At 5 hectares it is the sort of place you fish for an evening rather than a day. For a base, Pont Rouge sits 40 km out. Sainte-Jeanne-d'Arc is 42 km and Dolbeau-Mistassini 47 km. Nearby, in order: Lac Bernard (1 km), Lac de l'Herbe a Commis within 1.2 km, Lac Paula (1.9 km), Lac Tom within 2.1 km and Lac Robert (2.1 km). No border sits close enough to matter.

• Where to Fish on Lac Mathieu

  The records we hold are silent on depth, so plan to find it yourself. On a natural lake the weed line and the shelf beyond it do the work. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Saguenay/Lac-Saint-Jean list northern pike, Atlantic salmon and lake whitefish. Protected fish appear in the records for this area, so treat the list as information, not an invitation. On Lac Mathieu the obvious spot is not always the productive one.

• Seasonal Patterns

  Expect July near 17°C and January near -19°C on the long-run figures. The freeze holds for the better part of the year. The lid usually sets by midwinter and gives way around early May. Going by climate averages, expect open water from about early May until roughly mid November. From the thaw to midsummer the fishing improves week by week. It sets the rhythm of the year at Lac Mathieu.

• Tackle & Baits

  Whether you may fish here is not something records settle. There is no recorded infrastructure here; expect to find your own way in. For the pike, wire up and throw larger lures along the weed edges. A landowner's word beats anything printed elsewhere. Barbless rules turn up on managed water more often than not. Lac Bernard, 1 km away, makes the obvious fallback. Check the position on Lac Mathieu before loading the car.
