364-acre lake in Sudbury District, Ontario. The lake tops out around 108 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
On the chart, Acheson Lake draws 362 acres inside 5.3 miles of shoreline, broken up by an island. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. 22% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.4 mi, about 0.7 mi across. The water lies in Sudbury District. For a second option, 24 Mile Lake lies 5 mi southwest.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 32 to 108 ft, and winter fish settle into 20 to 80 ft. The spot to know is Deep basin, a deep basin in about 92 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (27 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 32 to 108 ft | dawn | Deep basin (92 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (27 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (49 ft) | White tube jig, Airplane jig |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 40 to 80 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Break off the point: a drop-off around 49 ft that scores prime in winter. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (92 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (92 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 | 20 to 60 ft | dawn | Break off the point (49 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring yellow perch on Acheson Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (92 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (92 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. As the season builds they drop to 3 to 12 ft, wintering in 10 to 25 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (92 ft) |
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Summer pushes them deeper, 32 to 108 ft, and winter fish settle into 15 to 60 ft. The spot to know is Deep basin, a deep basin in about 92 ft of water that rates prime for burbot in summer. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (49 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 32 to 108 ft | night & midday | Deep basin (92 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (49 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (49 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
