34-acre lake in Cochrane District, Ontario. The lake tops out around 96 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
Commando Lake maps at 33 acres behind 1.6 miles of shoreline. A middling shoreline index (2) gives it some bays to work without being a maze. Roughly 45% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.4 mi, about 0.2 mi across. Cochrane District claims this one. Norman Lake sits 0 mi south — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 29 to 96 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 82 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 29 to 96 ft | dawn | Deep basin (82 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (24 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (82 ft) | White tube jig, Airplane jig |
Spring splake on Commando Lake hold shallow, usually 5 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 10 to 45 ft. Put Break off the point first on the milk run — a drop-off near 43 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (24 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (43 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (43 ft) | Jigging spoon tipped with minnow head, Small white tube |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Main-lake point: a point around 24 ft that scores prime in fall. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (24 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (43 ft) | Jigging spoon, Tube jig (white) |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
