A rainy spell sitting over the area, with a working S breeze and steady pressure. Fish at Lac du Pertuis should hold close to the margins and the shelf beyond them. The day holds up well from night into morning. Let the water tell you when to move. Fish follow the bait in autumn, so find one to find the other.

In Quebec, Lac du Pertuis belongs to Mauricie. The surface lies 439 metres up. You can fish the entire water from one spot if you pick it well. It is one of the smaller waters we list in Mauricie. 44 km away sits La Tuque, the nearest town. Laurentides lies 64 km off, Métabetchouan another 78 km. Also worth knowing: Lac Croche 1 km away, Lac de la Botte within 1 km, Lac Girard 1.7 km away, Lac Nuage within 1.7 km and Lac Echo 2.1 km away. There is no boundary nearby to worry about.
Without a survey to go on, judge depth from how the bank falls away. Weed, then depth: that is the order to fish a water of this kind. The shallow end warms first and pulls fish in ahead of the rest. Records held for Mauricie cover northern pike, brook trout, walleye and yellow perch. County records show what lives in the area; the local agency holds the water-by-water list. At Lac du Pertuis the water rewards a slow, careful approach.
Typical July readings run about 17°C; by January the average is down near -16°C. The ice season is long here and the open one short. Ice fishing carries the winter, and the water opens about early May. In an average year the thaw lands around early May and the freeze near mid November. The strongest runs come at either end of the open season. That is the shape of the year on Lac du Pertuis.
Whether the bank is open is not something our records settle. The map shows no ramp or car park nearby, so this is a walk-in water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Local rules can differ across the county line, so check where you stand. Some ground is open by custom rather than by right, so tread carefully. Failing this one, try Lac Croche, 1 km away. The position on Lac du Pertuis is worth confirming on the day.
