474-acre lake in Sudbury District, Ontario. The lake tops out around 113 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here's the year, species by species, as the scoring engine sees it.
On the chart, Stull Lake draws 476 acres inside 6.8 miles of shoreline, broken up by an island. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 59% of this chart, as modeled. Figure 2.6 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Sudbury District. For a second option, Hamlow Lake lies 1 mi southeast.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 34 to 113 ft, wintering in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 96 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (28 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 34 to 113 ft | dawn | Deep basin (96 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (28 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (51 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 40 to 90 ft, then a winter hold in 25 to 70 ft. Start at Deep basin. It's a deep basin holding about 96 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (51 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (96 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (28 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (51 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 40 to 80 ft, then a winter hold in 20 to 60 ft. Start at Break off the point. It's a drop-off holding about 51 ft of water and rates prime come winter. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (96 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Break off the point (51 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 (51 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 (96 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (96 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| 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: burbot in 25 to 70 ft. As the season builds they drop to 34 to 113 ft, wintering in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 96 ft range, prime in summer. Time it for after dark and midday. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (51 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 34 to 113 ft | night & midday | Deep basin (96 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (51 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (51 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
