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.
