Low, flat cloud sitting over the water, with mild air moving in from the S and no real change in pressure. Give the calm side of the wind the first hour at Grand lac Clair. One clear peak today: the night. Cover water early, then settle where the signs are. The pre-winter feed makes autumn days generous.

Set in Mauricie, Grand lac Clair is a Quebec water. The water sits 416 metres up. At some 1.09 sq km it is far too large to cover on foot in a day. The outline measures near 7.0 km, so local knowledge counts. It ranks high for size among our Mauricie listings. For a base, Weymontachie sits 16 km out. Beyond it, La Tuque at 75 km and Leblanc at 75 km. The nearest edge is a long way off, so local rules apply throughout.
Nothing in our records gives a depth for this one. Look for the band where the shallows give up and the bottom falls away. A natural lake fishes on cover, and cover here means weed and timber. County-wide records name northern pike, brook trout, walleye and yellow perch. The list covers the county rather than this water alone, so treat it as a guide. On Grand lac Clair that means starting tight and working out.
July runs about 17°C on average, January about -16°C. The ice season is long here and the open one short. Count on hard cover from midwinter, and open water from early May. Ice usually gives way near early May, and forms again about mid November. Fishing peaks soon after break-up and again before the cold returns. Time your trip to Grand lac Clair by conditions rather than dates.
The rules here are undocumented as far as public sources go. No dam controls it, and the level follows the season. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. A small crankbait along the drop and a worm in the thick stuff cover the bass. Ask in the nearest town if you are unsure. Where parking is tight, arriving early solves most problems. The nearest alternative is Petit lac Clair, 1.4 km out. Nothing on Grand lac Clair should be assumed from this page alone.
