It is 69 km to Greater Sudbury, the nearest city. No border sits close enough to matter.

• Where to Fish on Byrne Lake

  Depth remains unrecorded, so treat the first session as a survey. Read the surface for the wind lane, then fish the edge of it. This is a lake, so the margins and the first drop matter most. County-wide records name smallmouth bass, pumpkinseed and yellow perch. County records show what lives in the area; the local agency holds the water-by-water list. On Byrne Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  Seasonal averages run from -12°C in January up to 19°C in July. The year runs cold to warm and back, with clear transitions. The lid usually goes in late April, which opens the strongest weeks of the year. Average temperatures cross freezing around late April in spring and again near early December in autumn. June through September is the settled part of the year, with the shoulders busier for fish. That shapes the year on Byrne Lake.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. There is no mapped parking or launch nearby, which keeps numbers down. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Sort the permit out before you load the car. Where parking is tight, arriving early solves most problems. Lac Chauvin, 4.5 km away, makes the obvious fallback. For Byrne Lake, the notice at the access point is the final word.
