Upper Sturgeon Lake, Ontario: Fishing Spots and Seasons

• Overview

  Upper Sturgeon Lake is one of the Sudbury listings for Ontario. It lies 193 metres above sea level. At 1.01 sq km this is proper open water rather than a pond. The perimeter runs near 11 km, so plan the walk before you start. It ranks high for size among our Sudbury listings. You are 37 km from Markstay-Warren. Greater Sudbury sits 48 km out, and it is the nearest city worth the name. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Upper Sturgeon Lake

  Depth remains unrecorded, so treat the first session as a survey. A soft bed grows weed late into autumn, which keeps fish shallow. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Sudbury names smallmouth bass, northern pike, yellow perch and Iowa darter. It is the county picture; the agency list is water-specific. Read Upper Sturgeon Lake for ten minutes before the first cast goes out.

• Seasonal Patterns

  On the long-term average, July reads 19°C and January reads -12°C. Four clear seasons, with a proper winter at one end. Winter locks it down, and late April brings it back. The open-water window runs from around late April to about early December in an average year. Right after break-up, and again as the nights sharpen, is when to go. On Upper Sturgeon Lake that shapes the whole year.

• Tackle & Baits

  Nothing in our records says who may fish here. No dam controls it, and the level follows the season. 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. Take the rules with you rather than trusting memory. Night access is frequently treated as a separate matter. Failing this one, try Lac Pomerleau, 2 km away. None of that is settled for Upper Sturgeon Lake in what we hold.
