149-acre lake in Nipissing District, Ontario. The lake tops out around 36 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 150 acres wrapped in 3.5 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 50% of this chart, as modeled. Call it 1.1 mi long by 0.5 mi wide at the broadest reach. Nipissing District claims this one. Gilmour Lake sits 1 mi west — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Break off the point. It's a drop-off holding about 16 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts cisco (lake herring) in skinny water — 9 to 36 ft is the zone. Summer fish stay in 11 to 36 ft, and winter fish hold in 11 to 36 ft. Deep basin is the standout, a deep basin at roughly 31 ft, rated prime for spring cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Deep basin (31 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 11 to 36 ft | dawn | Deep basin (31 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (16 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 11 to 36 ft | dawn | Deep basin (31 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (31 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring smallmouth bass on Tecumseh 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 11 to 36 ft. The chart's best answer is Main-lake point — point, 9 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 11 to 36 ft | midday | Break off the point (16 ft) | Blade bait, Hair jig |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season burbot use the shallows, holding in 11 to 36 ft. Even in summer they hold at 11 to 36 ft; winter keeps them in 9 to 36 ft. The chart's best answer is Deep basin — deep basin, 31 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 11 to 36 ft | night & dusk | Deep basin (31 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 11 to 36 ft | night & midday | Deep basin (31 ft) | Heavy jig + cut bait |
| Fall | 11 to 36 ft | night & dusk | Deep basin (31 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 9 to 36 ft | night & dusk | Deep basin (31 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
