• Where to Fish on Square Lake

  There is no recorded depth, so work from what you can see. 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. Reported across Parry Sound District: smallmouth bass, pumpkinseed, yellow perch and northern pike. It is the county picture; the agency list is water-specific. On Square Lake a short move beats a long cast.

• Seasonal Patterns

  Long-term averages put July at about 19°C and January near -8°C. Four clear seasons, with a proper winter at one end. After mid April the shallows warm and the fish move up. Average temperatures cross freezing around mid April in spring and again near early December in autumn. The shoulder weeks of the open season are the productive ones. Square Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Mapping records no facilities at all near this water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Look for a notice board at the entrance. Where parking is tight, arriving early solves most problems. Raby Lake at 0.9 km is the sensible second choice. Nothing on Square Lake should be assumed from this page alone.
