Lac Castor, Quebec: Fishing Spots and Seasons

• Overview

  In Quebec, Lac Castor belongs to Saguenay/Lac-Saint-Jean. Elevation runs to 455 metres. This is a pocket water of some 10 hectares, and every part of it is reachable from the bank. There is roughly 1.8 km of shoreline here, which is a short walk end to end. The town to know is Roberval, 44 km out. Saguenay is the closest city, 121 km away. There is no boundary nearby to worry about.

• Where to Fish on Lac Castor

  Nothing in our records gives a depth for this one. Still water like this holds fish on the edges rather than out in the open. Bays and points beat straight shoreline every time on water like this. Fish documented in Saguenay/Lac-Saint-Jean include northern pike, Atlantic salmon, lake whitefish and fallfish. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Lac Castor fishes better once you know its edges.

• Seasonal Patterns

  The year swings from about -18°C in January to roughly 16°C in July. The year here is short and sharp: a long lid, then a burst of open water. Look for the thaw near early May; the fishing lifts straight after. Ice clears near early May and comes back about mid November in a typical year. May into June fishes hardest, and September gives a second good stretch before the lid returns. Lac Castor runs to its own calendar within the local pattern.

• Tackle & Baits

  Access is not recorded for this water. It formed naturally, so levels move with rainfall rather than with a gate. The water borders Zec de la Lièvre, so reserve rules are likely to apply. For the pike, wire up and throw larger lures along the weed edges. Read any posted signs at the access point rather than assuming. Where parking is tight, arriving early solves most problems. If the gate is shut, Lac du Pit de Gravelle at 1.5 km is the nearest alternative. None of that is settled for Lac Castor in what we hold.
