259-acre lake in Nipissing District, Ontario. The lake tops out around 51 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Tanamakoon Lake draws 260 acres inside 5 miles of shoreline. With a shoreline index of 2.2, this water is all arms and coves — edge habitat well beyond its acreage. About 21% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 1.5 mi end to end and 0.7 mi across at its widest. The water lies in Nipissing District. The nearest mapped water is Found Lake, 1 mi to the northwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 15 to 51 ft, and winter fish settle into 13 to 51 ft. Deep basin is the standout, a deep basin at roughly 43 ft, rated prime for summer lake trout. Time it for early morning. 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 (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 15 to 51 ft | dawn | Deep basin (43 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 13 to 51 ft | dawn | Deep basin (43 ft) | White tube jig, Airplane jig |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 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. 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 | Break off the point (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Top water on the chart: Main-lake point, a point in the 13 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (13 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (23 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (13 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (23 ft) | Blade bait, Hair jig |
Spring pumpkinseed on Tanamakoon Lake hold shallow, usually 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 6 to 18 ft. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Prime time lands in 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 (6 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
