• Where to Fish on Cosens Lake

  We hold no depth figure for this one. Read the surface for the wind lane, then fish the edge of it. Where the bottom changes texture, fish gather; find that line. Survey and observation records for Thunder Bay District include cisco, blackfin cisco, rainbow smelt and bloater. The list covers the county rather than this water alone, so treat it as a guide. On Cosens Lake a short move beats a long cast.

• Seasonal Patterns

  Expect July near 16°C and January near -19°C on the long-run figures. The window is narrow, and fish feed hard while it lasts. Count on hard cover from midwinter, and open water from early May. From about early May to around mid November, expect open water on the long-run figures. May into June fishes hardest, and September gives a second good stretch before the lid returns. It holds true on Cosens Lake more years than not.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. Records list it as a natural water body rather than an impoundment. We find no slipway, car park or made path within a short radius, so treat access as rough. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Rules for this water may differ from the county norm. Where the way in crosses private ground, ask first. Pardee Lake at 1.9 km is the sensible second choice.
