An even grey lid over the water, with a light SE breeze and steady pressure. The productive water at Lac du Castor will be around sheltered bays and points. The day peaks in the morning. Fish confidently and change only when the bites stop. The autumn feed-up is on; baitfish areas are the key.

Set in Mauricie, Lac du Castor is a Quebec water. The coast is 34 km away. With some 17 hectares of water, there is room for a boat but no need of one. Bank access stretches around 1.7 km in total. By elevation it sits in the lower part of our Quebec listings. 16 km away sits Saint-Ubalde, the nearest town. Trois-Rivières sits 65 km out, and it is the nearest city worth the name. Two sets of local rules meet not far from this water.
Depth is not on record here, which means reading the ground instead. A soft bed grows weed late into autumn, which keeps fish shallow. A natural lake fishes on cover, and cover here means weed and timber. Fish documented in Mauricie include northern pike, brook trout and walleye. Those are county-wide records, so not every one of them will be in this water. On Lac du Castor the first feature you find is usually worth a session.
The warmest month averages 18°C, the coldest about -14°C. Winter closes the water for a while, and the reopening is worth catching. Break-up comes around late April, and the run that follows is short and strong. Averages suggest open water from about late April through to roughly late November. Early summer and early autumn carry the open-water season. The season on Lac du Castor rarely departs from it.
Nothing on record says whether the bank is open or closed. No dam controls it, and the level follows the season. Nothing is listed nearby for parking or launching a boat. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Where the road in crosses private land, ask first. Check whether bait restrictions apply before you buy any. The nearest alternative is Lac Beaudoin, 0.9 km out. Rules at Lac du Castor are worth checking on the day.
