A grey, even sky over the water, with a gentle ripple from the W and steady pressure. Whatever swims in Lac du Castor should be near reed fringes and open pockets. The forecast backs the stretch from the day. Ride the conditions while they last. Fish follow the bait in autumn, so find one to find the other.

In Quebec, Lac du Castor falls inside Mauricie. Around the bank it is rolling bush. At 6 hectares it is the sort of place you fish for an evening rather than a day. By elevation it sits in the lower part of our Quebec listings. Nearest place of any size is Hérouxville, 7.3 km away. The nearest city of size is Trois-Rivières, 43 km away. The nearest edge is a long way off, so local rules apply throughout.
Open data we checked carries no depth for this water. A soft bed grows weed late into autumn, which keeps fish shallow. The shallow end warms first and pulls fish in ahead of the rest. Records held for Mauricie cover northern pike, brook trout, walleye, yellow perch and white sucker. Those are county-wide records, so not every one of them will be in this water. On Lac du Castor a short move beats a long cast.
Long-term averages put July at about 19°C and January near -14°C. Fishing here follows the temperature more than the calendar. Expect a solid lid for months and a thaw around late April. On average, late April opens the water and late November closes it again. The strong weeks are the first after break-up and the last before the freeze. Plan any trip to Lac du Castor around it.
Nothing on record says whether the bank is open or closed. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Bank access can be seasonal on ground like this. Close seasons apply to some species and not others. Lac a la Truite sits 1.1 km off and takes the overflow. Signs at Lac du Castor carry more weight than any list.
