1,593-acre lake in Sudbury District, Ontario. The lake tops out around 59 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Upper Green Lake maps at 1,595 acres behind 13.1 miles of shoreline. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 52% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 2.8 mi of water from one end to the other, 1.9 mi at the beam. Sudbury District claims this one. Its nearest charted neighbour, Kashbogama Lake, is 2 mi to the east.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is an 18 to 59 ft game here, winter a 15 to 59 ft one. Start at Deep basin. It's a deep basin holding about 50 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 59 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 59 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 18 to 59 ft; cold water stacks them in 18 to 59 ft. Top water on the chart: Deep basin, a deep basin in the 50 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (27 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 59 ft | dawn | Deep basin (50 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (27 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 59 ft | midday & dawn | Deep basin (50 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 |
When the water first warms, burbot slide up into 18 to 59 ft. There's no big seasonal slide here — summer means 18 to 59 ft, winter 15 to 59 ft. Start at Deep basin. It's a deep basin holding about 50 ft of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 18 to 59 ft | night & dusk | Deep basin (50 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 18 to 59 ft | night & midday | Deep basin (50 ft) | Heavy jig + cut bait |
| Fall | 18 to 59 ft | night & dusk | Deep basin (50 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 59 ft | night & dusk | Deep basin (50 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
