Lac Castonguay in Nord-du-Québec: How and When to Fish It

• Overview

  Out in Nord-du-Québec, Quebec, sits Lac Castonguay. The bank gives way to spruce and muskeg. Roughly 7.08 sq km of surface: treat each bay as a water in its own right. At about 68 km of edge, most people fish a single area and learn it well. It is one of the larger waters we list anywhere in Quebec. Nearest place of any size is Lebel-sur-Quévillon, 46 km away. Senneterre is 78 km and Barraute 99 km. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Lac Castonguay

  Depth went unrecorded, which puts the reading back on you. The shallow end warms first and pulls fish in ahead of the rest. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Nord-du-Québec names Arctic charr, brook trout, lake trout, lake whitefish and cisco. County records show what lives in the area; the local agency holds the water-by-water list. The near bank of Lac Castonguay is often the one people ignore.

• Seasonal Patterns

  Between January at about -19°C and July at about 17°C, the water has a wide range to work through. Winter owns most of the year at this latitude. Ice fishing carries the winter, and the water opens about early May. Break-up near early May, freeze-up near mid November: that is the shape of an average year. Late spring and early autumn carry the year between them. Plan around that when you fish Lac Castonguay.

• Tackle & Baits

  We hold no note on access for this one. Records list it as a natural water body rather than an impoundment. Mapping is blank for access, so scout the approach before committing the car. For the trout, small spinners and a box of nymphs cover both approaches. A landowner's word beats anything printed elsewhere. Where tickets apply, they are sold in the nearest town rather than on the bank. Failing this one, try Lac Tee, 3.6 km away. Check the current arrangement for Lac Castonguay.
