Petrosky Lake Fishing Guide, Sudbury, Ontario

• Overview

  In Ontario, Petrosky Lake falls inside Sudbury. The setting is mixed forest. It runs to roughly 27 hectares — big enough to hold fish away from the bank, small enough to learn. The edge covers about 5.6 km, enough to hold several distinct areas. It sits higher than most water we list in Ontario. The closest town, Chapleau, is 47 km away. Greater Sudbury is the closest city, 233 km away. There is no boundary nearby to worry about.

• Where to Fish on Petrosky Lake

  No depth figure appears in our records, so the bank has to tell you. Bays and points beat straight shoreline every time on water like this. Look for the band where the shallows give up and the bottom falls away. Reported across Sudbury: smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. What holds for the county may not hold for this water. Fish Petrosky Lake to its features, not to its size.

• Seasonal Patterns

  July runs about 16°C on average, January about -15°C. The year runs cold to warm and back, with clear transitions. The lid usually sets by midwinter and gives way around late April. The water is typically free of ice between late April and mid November. Fish feed hardest at the start and the close of the open season. That is the shape of the year on Petrosky Lake.

• Tackle & Baits

  Access is not recorded for this water. It formed naturally, so levels move with rainfall rather than with a gate. There is no mapped parking or launch close by, which usually means walking in. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Read any posted signs at the access point rather than assuming. Access can change hands, so last year's answer may not hold. Hotspot Lake, 2.3 km away, makes the obvious fallback. None of that is settled for Petrosky Lake in what we hold.
