Lac Castonguay Fishing near Baie-Comeau, Quebec

• Overview

  Lac Castonguay sits in Côte-Nord, out in Quebec. Salt water lies 8.1 km off. Roughly 27 hectares: a morning covers one end, an afternoon the other. Around 2.7 km of margin, front to back. By elevation it sits in the lower part of our Quebec listings. Baie-Comeau sits 24 km from the bank. The big place round here is Saguenay, 253 km distant. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Lac Castonguay

  The records we hold are silent on depth, so plan to find it yourself. Where the bottom changes texture, fish gather; find that line. This is a lake, so the margins and the first drop matter most. Côte-Nord records list logperch among the fish reported. It is the county picture; the agency list is water-specific. The near bank of Lac Castonguay is often the one people ignore.

• Seasonal Patterns

  Seasonal averages run from -15°C in January up to 16°C in July. The year splits cleanly: hard water, then open water. The lid usually sets by midwinter and gives way around early May. Average temperatures cross freezing around early May in spring and again near mid November in autumn. The strong weeks are the first after break-up and the last before the freeze. Plan any trip to Lac Castonguay around it.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. Records list it as a natural water body rather than an impoundment. The map shows no ramp or car park nearby, so this is a walk-in water. For the perch, a small jig tipped with worm, dropped along the edges, is hard to beat. Season dates differ by species, so read the table. Signs go up and come down, so check on the day. If the gate is shut, Lac a Foin at 1.2 km is the nearest alternative. Ask locally about Lac Castonguay if anything is unclear.
