• Where to Fish on Lac O'Bomsawin

  No depth figure has reached our records, which makes a plummet useful. A natural lake fishes on cover, and cover here means weed and timber. A soft bed grows weed late into autumn, which keeps fish shallow. Records held for Mauricie cover northern pike, brook trout, walleye, yellow perch and white sucker. Records at county level tell you what is around, not what is stocked here. Lac O'Bomsawin responds to conditions more than to tactics.

• Seasonal Patterns

  The warmest month averages 17°C, the coldest about -16°C. The year runs cold to warm and back, with clear transitions. Firm cover through the cold months, then open water from late April. On the long-run averages the water opens up around late April and starts locking again about mid November. The open run goes from the thaw to the freeze, and April through October covers most of it. Anyone fishing Lac O'Bomsawin regularly works to that calendar.

• Tackle & Baits

  No public source sets out the position on this bank. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check locally before you travel, because a wasted drive is a long one. Rules for boats are stricter than rules for the bank in many places. Failing this one, try Lac Ann, 0.8 km away. Check the position at Lac O'Bomsawin before loading the car.
