216-acre lake in Rainy River District, Ontario. The lake tops out around 59 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Silvia L. draws 217 acres inside 5 miles of shoreline. A development index of 2.4 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 28% of the surface on the model — that's where the groceries are. Figure 1.2 mi of water from one end to the other, 0.8 mi at the beam. You'll find it in Rainy River District. The nearest mapped water is Lower Furlonge Lake, 2 mi to the west.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 18 to 59 ft; cold water stacks them in 15 to 59 ft. Deep basin is the standout, a deep basin at roughly 50 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| 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 chart-limited; documented 50 to 120 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 chart-limited; documented 20 to 80 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is an 18 to 59 ft game here, winter an 18 to 59 ft one. The chart's best answer is Deep basin — deep basin, 50 ft, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| 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 chart-limited; documented 40 to 90 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 chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (50 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down 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. 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 (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
