Fishing at Whalsom Lake, Sudbury, Ontario

• Overview

  Set in Sudbury, Whalsom Lake is an Ontario water. It sits in northern bush country. At some 3.70 sq km it is far too large to cover on foot in a day. Around 23 km of bank, which is a long day on foot. It ranks high for size among our Sudbury listings. Some 92 km away sits Timmins, the nearest settlement. Beyond it, Chapleau at 108 km and Dowling at 137 km. It lies deep inside the county rather than near an edge.

• Where to Fish on Whalsom Lake

  Nothing in our records gives a depth for this one. The productive water is a rod length or two out, not a hundred. A natural lake fishes on cover, and cover here means weed and timber. County-wide records name smallmouth bass, northern pike, yellow perch and Iowa darter. Records at county level tell you what is around, not what is stocked here. Fish Whalsom Lake where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  Long-run averages give July about 17°C and January about -17°C. The year here is short and sharp: a long lid, then a burst of open water. Firm cover through the cold months, then open water from early May. On the long-run averages the water opens up around early May and starts locking again about mid November. Early summer and early autumn carry the open-water season. That is the shape of the year on Whalsom Lake.

• Tackle & Baits

  We hold no note on access for this one. No dam controls it, and the level follows the season. Nothing is listed nearby for parking or launching a boat. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Local rules can differ across the county line, so check where you stand. Access can change hands, so last year's answer may not hold. Failing this one, try Billie Lake, 5.7 km away. For Whalsom Lake in particular, ask before you travel.
