Gagnon Lake Fishing in Sudbury, Ontario

• Overview

  In Ontario, Gagnon Lake falls inside Sudbury. The surroundings are rolling bush. This is a pocket water of some 3 hectares, and every part of it is reachable from the bank. It is one of the smaller waters we list in Sudbury. The closest town, Markstay-Warren, is 33 km distant. The nearest city of size is Greater Sudbury, 53 km away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Gagnon Lake

  Depth remains unrecorded, so treat the first session as a survey. Still water like this holds fish on the edges rather than out in the open. Read the surface for the wind lane, then fish the edge of it. Fish documented in Sudbury include smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. Read it as a county summary, not a water-by-water list. Take Gagnon Lake a stretch at a time.

• Seasonal Patterns

  Temperature averages peak at 18°C in July and bottom out at -14°C in January. The middle months are generous; the ends are demanding. Firm cover through the cold months, then open water from late April. The open-water window runs from around late April to about late November in an average year. From the thaw to midsummer the fishing improves week by week. On Gagnon Lake the same rules apply, with local timing.

• Tackle & Baits

  Ownership and access are not documented in what we hold. There is no mapped parking or launch nearby, which keeps numbers down. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Sort the permit out before you load the car. Fishing rules and camping rules are set separately here. The nearest alternative is Gawasi Lake, 0.9 km out. Nothing here settles the position at Gagnon Lake for certain.
