Rules here are straightforward: one set of provincial rules.

• Where to Fish on Lac Trefle

  Our records hold no depth for this water. This is a lake, so the margins and the first drop matter most. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for Mauricie names northern pike, brook trout, walleye, yellow perch and white sucker. What holds for the county may not hold for this water. Work Lac Trefle in sections rather than trying to cover it.

• Seasonal Patterns

  The warmest month averages 16°C, the coldest about -17°C. The ice season is long here and the open one short. Winter fishing happens on the ice here, with open water back around early May. Climate averages put the opening at about early May and the closing near mid November. The strong weeks are the first after break-up and the last before the freeze. It holds true on Lac Trefle more years than not.

• Tackle & Baits

  Access status is simply unknown for this water. It formed naturally, so levels move with rainfall rather than with a gate. Access points are not mapped for this water, which suits people who like quiet. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check whether a boat is allowed before you tow one. Rules for boats are stricter than rules for the bank in many places. Lac Mystere, 1.7 km away, makes the obvious fallback. None of that is settled for Lac Trefle in what we hold.
