Freshwater Fishing.
The upper St. Lawrence at South Stormont sits in Fisheries Management Zone 20 — muskellunge, smallmouth and largemouth bass, walleye, and northern pike on Lake St.
Lawrence, accessed from the Long Sault Parkway boat launches. Inland, the Raisin River and tributaries fall under FMZ 18, with warm-water species and a separate season / limit table.
The brief.
FMZ 20 and FMZ 18 run on different open seasons and possession limits — the boundary cuts through South Stormont, so anglers should confirm zone before each trip and carry a copy of the current Ontario Fishing Regulations Summary or the digital app. Bait restrictions apply across both zones (Southern Bait Management Zone).
A valid Outdoors Card and fishing licence are required. The Lake St.
Lawrence pool is productive for muskie and bass and has been a long-running upper-Seaway fishery; inland Raisin River reaches are smaller-water warm-water angling.
