259-acre lake in Sudbury District, Ontario. The lake tops out around 62 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1980 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Seagram Lake draws 259 acres inside 6 miles of shoreline. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 59% of the surface — that's where the groceries are. End to end it runs roughly 2.2 mi, about 0.5 mi across. You'll find it in Sudbury District. Closest neighbour on DepthScout: Linger Lake, 1 mi southeast of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Main-lake point, a prime-rated point around 11 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (11 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (35 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (11 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (1 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 19 to 62 ft before dropping to 16 to 62 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 52 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 (11 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 19 to 62 ft | dawn | Deep basin (52 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 62 ft | dawn | Deep basin (52 ft) | White tube jig, Airplane jig |
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 Break off the point. It's a drop-off holding about 35 ft of water and rates prime come fall. 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (35 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (35 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (35 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 1 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (11 ft) | Tip-ups, Large jigging spoon |
Spring rock bass on Seagram Lake hold shallow, usually 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. Put Main-lake point first on the milk run — a point near 11 ft that grades prime for summer. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (11 ft) | 1/16 oz jig + grub, Small inline spinner |

Spring pumpkinseed on Seagram Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
