Lac Grenier near Shawinigan: Fishing Spots, Seasons and Access

• Overview

  In Quebec, Lac Grenier falls inside Mauricie. The surface lies 262 metres up. About 3 hectares of surface, which puts the far bank inside easy sight. It is a small entry by Mauricie standards. You are 13 km from Shawinigan. Hérouxville is 19 km away, with Saint-Élie-de-Caxton at 20 km. Also on the doorstep: Lac Minogami (1.2 km), Lac Pratte 2.7 km away, Lac McLaren (2.9 km), Lac a la Peche 3.1 km away and Lac Albert (3.1 km). It sits well inside the county, so one set of rules covers it.

• Where to Fish on Lac Grenier

  Depth is unmeasured here, so let the shoreline guide you. Look for the band where the shallows give up and the bottom falls away. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Mauricie list northern pike, brook trout and walleye. The list covers the county rather than this water alone, so treat it as a guide. The shape of Lac Grenier decides where the fish sit.

• Seasonal Patterns

  Climate normals give 18°C for July and -14°C for January. Winter shuts the surface down for months. Winter fishing happens on the ice here, with open water back around late April. Averages suggest open water from about late April through to roughly late November. The weeks after the thaw and the ones before the freeze are the strongest. It sets the rhythm of the year at Lac Grenier.

• Tackle & Baits

  No public source sets out the position on this bank. A jetty or pier is mapped about 860 m from here. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check whether a boat is allowed before you tow one. Where tickets apply, they are sold in the nearest town rather than on the bank. Lac Minogami, 1.2 km away, makes the obvious fallback. What applies at Lac Grenier may have changed since it was mapped.
