Mavis Lake in Thunder Bay District: How and When to Fish It

• Overview

  In Ontario, Mavis Lake falls inside Thunder Bay District. It stands 325 metres above sea level. Around 35 hectares of surface means several distinct areas to work. About 3.2 km of bank, so nothing stays unexplored for long. Hornepayne lies 45 km from the water. Thunder Bay is the closest city, 310 km away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Mavis Lake

  No depth figure appears in our records, so the bank has to tell you. The productive water is a rod length or two out, not a hundred. This is a lake, so the margins and the first drop matter most. Records held for Thunder Bay District cover cisco, blackfin cisco and rainbow smelt. These are county-wide records, so not all of them will be in this water. Work Mavis Lake in sections rather than trying to cover it.

• Seasonal Patterns

  Seasonal averages run from -18°C in January up to 16°C in July. Little of the calendar is open water, so timing counts for everything. Ice-out usually falls in early May, and the weeks after it fish hardest. Going by climate averages, expect open water from about early May until roughly mid November. The first weeks of open water and the last are the ones to plan for. Plan around that when you fish Mavis Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. No dam controls it, and the level follows the season. The map shows no ramp or car park nearby, so this is a walk-in water. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Season dates differ by species, so read the table. Some stretches are reserved and marked as such on the ground. For a change of water, Puttock Lake is 3.2 km distant. For Mavis Lake in particular, ask before you travel.
