Lac de la Grosse in Lanaudière: How and When to Fish It

• Overview

  Lac de la Grosse lies in Lanaudière, in Quebec. The land about it is rolling bush. It covers about 7 hectares, so this is small water you can walk round in under an hour. Saint-Michel-des-Saints lies 23 km from the water. Mandeville is 43 km away, with Saint-Gabriel at 49 km. Nearby, in order: Lac Chevelu out at 0.6 km, Lac Biro (1.1 km), Lac de la Tete out at 1.2 km, Lac Daniet (1.5 km) and Lac Mineur out at 2 km. Rules here are straightforward: one set of provincial rules.

• Where to Fish on Lac de la Grosse

  Depth is not on record here, so the bank has to tell you. Weed, then depth: that is the order to fish a water of this kind. This is a lake, so the margins and the first drop matter most. Open biodiversity records for Lanaudière list pumpkinseed, smallmouth bass, yellow perch and rock bass. County records show what lives in the area; the local agency holds the water-by-water list. On Lac de la Grosse the obvious spot is not always the productive one.

• Seasonal Patterns

  The seasonal spread runs -15°C to 17°C. Spring and autumn carry the fishing; summer and winter test it. Look for the thaw near early May; the fishing lifts straight after. Open water usually runs from early May until about late November. Just after the ice goes and just before it returns, the fishing lifts. At Lac de la Grosse the season follows that pattern closely.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Access is unmapped, which usually means a farm track and a walk. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking is often the real limit rather than the bank itself. Some ground is open by custom rather than by right, so tread carefully. If the gate is shut, Lac Chevelu at 0.6 km is the nearest alternative. Signs at Lac de la Grosse carry more weight than any list.
