Lac Thompson in Laurentides: How and When to Fish It

• Where to Fish on Lac Thompson

  We hold no survey for this water; read the slope of the shoreline instead. This is a lake, so the margins and the first drop matter most. Still water like this holds fish on the edges rather than out in the open. Public occurrence data for Laurentides names pumpkinseed, smallmouth bass, yellow perch, brook trout and rock bass. What holds for the county may not hold for this water. The shape of Lac Thompson rewards a slow walk along one bank.

• Seasonal Patterns

  Climate normals give 18°C for July and -14°C for January. The year splits cleanly: hard water, then open water. After late April the shallows warm and the fish move up. Open water usually runs from late April until about late November. Look to early summer and the first cool weeks of autumn. Time your trip to Lac Thompson by conditions rather than dates.

• Tackle & Baits

  We have no record of the rules that apply on this bank. Mapping records no facilities at all near this water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Take the rules with you rather than trusting memory. Access can change hands, so last year's answer may not hold. For a change of water, Lac Castor is 0.8 km distant.
