• Where to Fish on Mystery Lake

  No figure exists for depth, so let the water show you. This is a lake, so the margins and the first drop matter most. On a natural lake the weed line and the shelf beyond it do the work. Across Thunder Bay District, recorded fish include cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. Take it as the county picture rather than a promise for this water. On Mystery Lake that means starting tight and working out.

• Seasonal Patterns

  The year swings from about -21°C in January to roughly 17°C in July. Hard water is a season in its own right here. After early May the shallows warm and the fish move up. Ice usually gives way near early May, and forms again about mid November. Right after break-up, and again as the nights sharpen, is when to go. Plan around that when you fish Mystery Lake.

• Tackle & Baits

  Whether you may fish here is not something records settle. It formed naturally, so levels move with rainfall rather than with a gate. Mapping records no facilities at all near this water. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Some banks are open only from a marked point. Some water is controlled locally without a sign saying so. Osprey Lake, 5.3 km away, makes the obvious fallback. None of that is settled for Mystery Lake in what we hold.
