Lac a Treffle in Saguenay/Lac-Saint-Jean: How and When to Fish It

• Overview

  This water sits in Saguenay/Lac-Saint-Jean, Quebec. The bank is 304 metres above sea level. The water covers some 52 hectares, so pick a bank rather than trying to cover it all. The outline measures near 6.0 km, so local knowledge counts. Size puts it in the front rank of our Saguenay/Lac-Saint-Jean list. Nearest place of any size is Albanel, 50 km away. Dolbeau-Mistassini follows at 51 km, then Pont Rouge at 54 km. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Lac a Treffle

  Our records carry no depth, so judge it from the bank. Where the bottom changes texture, fish gather; find that line. The productive water is a rod length or two out, not a hundred. Records held for Saguenay/Lac-Saint-Jean cover northern pike, Atlantic salmon, lake whitefish and fallfish. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Lac a Treffle gives up its fish to patience rather than distance.

• Seasonal Patterns

  Typical July readings run about 16°C; by January the average is down near -20°C. Little of the calendar is open water, so timing counts for everything. The freeze runs deep into the year, with break-up near early May. The open-water window runs from around early May to about mid November in an average year. The strongest runs come at either end of the open season. The season on Lac a Treffle rarely departs from it.

• Tackle & Baits

  No public source sets out the position on this bank. No dam controls it, and the level follows the season. Mapping records no facilities at all near this water. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. Parking is often the real limit rather than the bank itself. Where tickets apply, they are sold in the nearest town rather than on the bank. The nearest alternative is Lac du Canot, 1.8 km out. Check the position on Lac a Treffle before loading the car.
