Lac Cosgrove Fishing Guide, Mauricie, Quebec

• Overview

  Lac Cosgrove stands in Mauricie, Quebec. Around the bank it is pine and birch. Small at around 2 hectares: two anglers spread out cover most of it. On size it sits at the modest end of our Mauricie list. Nearest place of any size is La Tuque, 19 km away. Trois-Rivières is the closest city, 108 km away. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Lac Cosgrove

  We hold no survey for this water; read the slope of the shoreline instead. A soft bed grows weed late into autumn, which keeps fish shallow. Bays and points beat straight shoreline every time on water like this. Fish documented in Mauricie include northern pike, brook trout, walleye, yellow perch and white sucker. County records show what lives in the area; the local agency holds the water-by-water list. On Lac Cosgrove the quiet end is the one worth the extra effort.

• Seasonal Patterns

  Climate records put July near 17°C and January near -16°C. The freeze arrives properly here and holds. The lid arrives early and lasts until roughly late April. Break-up sits around late April on average, with the water closing again about late November. The shoulder weeks of the open season are the productive ones. Plan any trip to Lac Cosgrove around it.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. No made access is recorded, so a short walk in is the likely arrangement. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Season dates differ by species, so read the table. Rules for boats are stricter than rules for the bank in many places. Lac au Bouleau at 0.4 km is the sensible second choice. Confirm before you fish Lac Cosgrove.
