275-acre lake in Cochrane District, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
On the chart, Fortune Lake draws 277 acres inside 3.1 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 47% of the surface — that's where the groceries are. End to end it runs roughly 1 mi, about 0.7 mi across. You'll find it in Cochrane District. For a second option, Montcalm L. 6 lies 8 mi west.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 13 to 50 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 50 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 15 to 50 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 13 to 50 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Spring puts splake in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 10 to 45 ft. Break off the point is the standout, a drop-off at roughly 48 ft, rated prime for summer splake. Plan around early morning and the evening in the warm months. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 15 to 50 ft | dawn & dusk | Break off the point (48 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (48 ft) | Jigging spoon tipped with minnow head, Small white tube |
Spring cisco (lake herring) on Fortune Lake hold shallow, usually 10 to 40 ft. They move out to 15 to 50 ft in summer and finish the year down in 15 to 50 ft. Put Deep basin first on the milk run — a deep basin near 50 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (50 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 50 ft | dawn | Deep basin (50 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 50 ft | dawn | Deep basin (50 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (50 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (50 ft) | Tungsten jig + spikes, Rattle spoon (small) |
