How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish lake sturgeon in Ontario
- Spring 3–15 ft — Spawning runs stack fish below rapids, dam faces and river mouths — check the regs, many runs are closed water.
- Summer 15–40 ft — Soft-bottom flats and holes near current — sturgeon vacuum larvae and snails off the mud, mostly after dark.
- Fall 15–45 ft — The prime rod-and-reel season — fish feed hard on deep mud and channel bends before winter.
- Winter 20–60 ft — Fish pod up over deep mud basins — the famous Winnebago spear season happens over exactly this pattern.
