• Where to Fish on Flour Lake

  The deepest measured water here is close to 25 metres. This is a lake, so the margins and the first drop matter most. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for Thunder Bay District names cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. Read it as a county summary, not a water-by-water list. The near bank of Flour Lake is often the one people ignore.

• Seasonal Patterns

  The year swings from about -15°C in January to roughly 17°C in July. Fishing here follows the temperature more than the calendar. Ice fishing carries the winter, and the water opens about late April. Break-up near late April, freeze-up near mid November: that is the shape of an average year. The open run goes from the thaw to the freeze, and April through October covers most of it. Flour Lake runs to that rhythm year in and year out.

• Tackle & Baits
