    About this water

    A sheltered Erie bay famous for trophy largemouth bass, panfish, and a healthy pike population in the north end marshes.

    Shallow, weedy bay protected by a peninsula. Excellent panfish and bass structure — most water under 10 ft.

    FMZ 19 regulations — Lake Erie

    The Canadian waters of Lake Erie — the shallowest and most productive Great Lake — together with Lake St. Clair and the Detroit, St. Clair and Upper Niagara Rivers. It is not the Lake Ontario zone.

    • Walleye: open all year on Erie; S-4/C-2 – 46 cm min (varies by area, check).
    • Yellow perch: open all year; S-50/C-25 (Erie).
    • Muskie (St. Clair): 3rd Sat in June – Dec 15; 137 cm min, S-1/C-0.
    • Smallmouth bass: last Sat in June – Dec 15 on Erie; S-6/C-2.

    Zone check: FMZ 19 set by review — Great Lakes water body: access point on Lake Erie, Lake St. Clair or a connecting channel. Coordinate falls on the land side of the mapped boundary, so the zone is set from the water actually fished. Reviewed 2026-08-12.

    Fishing tips

    • Erie perch stack tight to structure — bottom rigs with emerald shiners produce.
    • St. Clair muskie sight-fishing shines in the shallow south basin all summer.
    • Topwater frogs over the pad fields early and late produce the biggest bass. For panfish, drift small jigs off the launch weed lines.
    • Access: Rondeau Provincial Park boat launch and shore access; day-use pass required.
