Lac Grosleau near Laurentides: Fishing Spots, Seasons and Access

• Overview

  Within Mauricie, Quebec, you have Lac Grosleau. Beyond the shoreline you have pine and birch. At about 19 hectares, a day is enough to walk the shoreline properly. There is roughly 4.7 km of shoreline here, which is a short walk end to end. Laurentides sits 34 km from the bank. The big place round here is Trois-Rivières, 88 km distant. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Lac Grosleau

  Depth went unrecorded, which puts the reading back on you. Bays and points beat straight shoreline every time on water like this. Still water like this holds fish on the edges rather than out in the open. Fish documented in Mauricie include northern pike, brook trout and walleye. These are county-wide records, so not all of them will be in this water. Work Lac Grosleau in sections rather than trying to cover it.

• Seasonal Patterns

  In an average year July sits at 18°C and January at -15°C. The year splits cleanly: hard water, then open water. The lid arrives early and lasts until roughly late April. The water is typically free of ice between late April and late November. The weeks after the thaw and the ones before the freeze are the strongest. Time your trip to Lac Grosleau by conditions rather than dates.

• Tackle & Baits

  Nothing in our records says who may fish here. No dam controls it, and the level follows the season. Formal access is not mapped, so the last stretch is likely on foot. A small crankbait along the drop and a worm in the thick stuff cover the bass. A landowner's word beats anything printed elsewhere. A polite question at the farm gate opens more banks than anything else. If the gate is shut, Lac Monteil at 3 km is the nearest alternative. Rules at Lac Grosleau are worth checking on the day.
