Freshwater Fishing.

Lake St. Francis along South Glengarry sits within Ontario Fisheries Management Zone 20 — the upper St.

Lawrence pool — and supports muskellunge, smallmouth and largemouth bass, walleye, northern pike, and yellow perch. The Charlottenburgh Park boat launch is the in-township access point onto the lake, and the Raisin River corridor inland falls under FMZ 18 with separate seasons and limits.

Freshwater Fishing in South Glengarry
01 — What to know

The brief.

FMZ 20 covers the Lake St. Francis pool along South Glengarry; FMZ 18 covers the inland Raisin River and tributaries.

The two zones have separate seasons, slot limits, and species-specific rules — a Lake St. Francis muskie or walleye trip and an inland Raisin River bass trip are governed by different Ontario regulations summaries.

Spring and summer are the open-water windows; ice fishing is possible on Lake St. Francis backwaters where conditions allow.

The Charlottenburgh Park boat launch is the marked in-township launch onto the lake.
