Fishing at Trethewey Lake, Timiskaming District, Ontario

The margin runs to about 24 km in total. It is among the larger waters listed here for Timiskaming District. For a base, Temiskaming Shores sits 59 km out. It is 112 km to Greater Sudbury, the nearest city. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Trethewey Lake

  Depth went unrecorded, which puts the reading back on you. Bays and points beat straight shoreline every time on water like this. This is a lake, so the margins and the first drop matter most. County-wide records name brook trout, northern pike, yellow perch, Iowa darter and walleye. Those are county-wide records, so not every one of them will be in this water. On Trethewey Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  In an average year July sits at 17°C and January at -16°C. Spring and autumn carry the fishing; summer and winter test it. Winter locks it down, and early May brings it back. Climate figures give an open season running early May to mid November. From the thaw to midsummer the fishing improves week by week. Plan any trip to Trethewey Lake around it.

• Tackle & Baits

  Ownership and access are not documented in what we hold. Records list it as a natural water body rather than an impoundment. No made access is recorded, so a short walk in is the likely arrangement. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Rules for this water may differ from the county norm. Some ground is open by custom rather than by right, so tread carefully. Failing this one, try Weedend Lake, 4.7 km away. Signs at Trethewey Lake carry more weight than any list.
