225-acre lake in Rainy River District, Ontario. The lake tops out around 92 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
The drawn water covers 228 acres wrapped in 6.7 miles of bank — one island included. A development index of 3.2 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 19% of the surface on the model — that's where the groceries are. Figure 1.7 mi of water from one end to the other, 0.6 mi at the beam. Rainy River District claims this one. If the bite dies, Dad Lake is 2 mi to the south.
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 28 to 92 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 78 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
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 (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 28 to 92 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (78 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (23 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (78 ft) | White tube jig, Airplane jig |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 78 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (41 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (78 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (78 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
