Threecorner Lake, Ontario: Fishing Spots and Seasons

• Overview

  Threecorner Lake falls in Greater Sudbury, part of Ontario. It sits in mixed forest country. With some 25 hectares of water, there is room for a boat but no need of one. Bank access stretches around 3.3 km in total. Ground here is low by Ontario standards. Lively is the closest town at 25 km. For a city, Greater Sudbury is 39 km off. There is no boundary nearby to worry about.

• Where to Fish on Threecorner Lake

  Nothing in our records gives a depth for this one. On a natural lake the weed line and the shelf beyond it do the work. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Greater Sudbury list smallmouth bass, yellow perch and northern pike. These are county-wide records, so not all of them will be in this water. On Threecorner Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  The warm month here averages 18°C; the cold one sits at -12°C. Winter shuts things down for a spell, then spring reopens them fast. Ice-out usually falls in late April, and the weeks after it fish hardest. Open water usually runs from late April until about early December. Right after break-up, and again as the nights sharpen, is when to go. That shapes the year on Threecorner Lake.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. This is a natural basin, not a dammed one. Nothing formal is recorded here: no ramp, no car park, no marked path. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Read any posted signs at the access point rather than assuming. A polite question at the farm gate opens more banks than anything else. Ann Lake sits 1.6 km off and takes the overflow. Nothing here settles the position at Threecorner Lake for certain.
