Ranked below by size and depth-data quality — open any water to see exactly where to fish it: depth contours, scored spots with plain-English reasons, seasonal windows and bait picks. Stocked brook × lake trout hybrid — the Shield-lake specialty that splits the difference: shallower than lakers, deeper than brookies, and a superb ice bite.

When to fish splake in Ontario

• Spring 5–25 ft — Ice-out through spring, splake patrol shoreline rock, points and inflows like oversized brookies.
• Summer 25–60 ft — Warm water pushes splake below the thermocline — deep breaks and humps, shallower than lakers in the same lake.
• Fall 10–35 ft — Mostly sterile but still hormone-driven — fall splake stage on rock shoals and points and eat aggressively.
• Winter 10–45 ft — Why they're stocked: an active, roaming winter predator — work basin edges and mid-depth humps, and hole-hop.
