59-acre lake in Sudbury District, Ontario. The lake tops out around 85 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
On the chart, Green Lake draws 58 acres inside 1.5 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. About 23% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. You'll find it in Sudbury District. For a second option, Pike Lake lies 1 mi north.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 26 to 85 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 72 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 (21 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 26 to 85 ft | dawn | Deep basin (72 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (21 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (72 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 25 to 60 ft; cold water stacks them in 10 to 45 ft. Break off the point is the standout, a drop-off at roughly 38 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 (21 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (38 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (21 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (38 ft) | Jigging spoon tipped with minnow head, Small white tube |
Spring lake whitefish on Green Lake hold shallow, usually 15 to 45 ft. They move out to 26 to 85 ft in summer and finish the year down in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 72 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (38 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 26 to 85 ft | dawn | Deep basin (72 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (21 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (72 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring cisco (lake herring) on Green Lake hold shallow, usually 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft. Put Deep basin first on the milk run — a deep basin near 72 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 | Break off the point (38 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (72 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

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 6 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 (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 | Break off the point (38 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (72 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| 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 |
