242-acre lake in Nipissing District, Ontario. The lake tops out around 25 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Billy Lake runs 243 acres with 3.5 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Roughly 63% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 1.1 mi end to end and 0.6 mi across at its widest. You'll find it in Nipissing District. For a second option, Oram Lake lies 1 mi east.
Spring puts lake trout in skinny water — 6 to 25 ft is the zone. Summer fish stay in 8 to 25 ft, and winter fish hold in 6 to 25 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 25 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 6 to 25 ft | dawn | Deep basin (21 ft) | White tube jig, Airplane jig |
In spring, splake run shallow here, mostly 5 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 6 to 25 ft. Summer splake concentrate at Break off the point, a prime-rated drop-off around 11 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 8 to 25 ft | dawn & dusk | Break off the point (11 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 7 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait |
| Winter | 6 to 25 ft | dawn | Break off the point (11 ft) | Jigging spoon tipped with minnow head, Small white tube |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 21 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (3 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (21 ft) |
