• Where to Fish on Lac du Grand Castor

  Depth went unrecorded, which puts the reading back on you. This is a lake, so the margins and the first drop matter most. Bays and points beat straight shoreline every time on water like this. County-wide records name northern pike, brook trout, walleye, yellow perch and white sucker. County records show the wider picture rather than this one place. Read Lac du Grand Castor before you fish it and the day goes better.

• Seasonal Patterns

  In an average year July sits at 16°C and January at -17°C. Little of the calendar is open water, so timing counts for everything. The lid arrives early and lasts until roughly early May. On the long-run averages the water opens up around early May and starts locking again about mid November. Look to early summer and the first cool weeks of autumn. It holds true on Lac du Grand Castor more years than not.
