Thedan Lake, Ontario: Fishing Spots and Seasons

• Overview

  Thedan Lake is one of the Sudbury listings for Ontario. The surface lies 395 metres up. With some 19 hectares of water, there is room for a boat but no need of one. Shoreline comes to about 2.1 km, small enough to learn in a day. You are 62 km from Chapleau. Greater Sudbury is the closest city, 194 km away. It sits well inside its county, with no border complications.

• Where to Fish on Thedan Lake

  There is no recorded depth, so work from what you can see. On a natural lake the weed line and the shelf beyond it do the work. A soft bed grows weed late into autumn, which keeps fish shallow. Open biodiversity records for Sudbury list smallmouth bass, northern pike and yellow perch. The county list is broader than any single water. Treat Thedan Lake as a water to read rather than to cover.

• Seasonal Patterns

  The range across the year is -16°C to 17°C. Winter runs most of the calendar, and everything worth doing happens in the gap. Break-up comes around late April, and the run that follows is short and strong. The open-water window runs from around late April to about mid November in an average year. May into June fishes hardest, and September gives a second good stretch before the lid returns. Thedan Lake fishes to that pattern most years.

• 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. No made access appears within a short radius, so plan to park on a verge and walk. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Rules differ from one water to the next round here. Close seasons apply to some species and not others. For a change of water, Squash Lake is 1.2 km distant.
