Rosebary Lake, Ontario: Fishing Spots and Seasons

No county line comes close, which keeps the paperwork simple.

• Where to Fish on Rosebary Lake

  Depth here is unknown, so count the lead down before committing. Where the bottom changes texture, fish gather; find that line. The shallow end warms first and pulls fish in ahead of the rest. County-wide records name smallmouth bass, pumpkinseed and yellow perch. County records show the wider picture rather than this one place. The shape of Rosebary Lake decides where the fish sit.

• Seasonal Patterns

  Between January at about -13°C and July at about 18°C, the water has a wide range to work through. Hard water is a season in its own right here. Expect a solid lid for months and a thaw around late April. Average temperatures cross freezing around late April in spring and again near late November in autumn. May into June fishes hardest, and September gives a second good stretch before the lid returns. Keep it in mind when planning a trip to Rosebary Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. There is a campsite 500 m from the water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. A phone call first saves an afternoon. Check whether bait restrictions apply before you buy any. For a change of water, Floating Heart Lake is 1.4 km distant. What applies at Rosebary Lake may have changed since it was mapped.
