10-acre lake in Thunder Bay District, Ontario. The lake tops out around 39 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Noble Lake runs 10 acres with 0.6 miles of edge. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 37% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.3 mi end to end. You'll find it in Thunder Bay District. The nearest mapped water is Blue Lake, 1 mi to the east.
Early season lake whitefish use the shallows, holding in 12 to 39 ft. Even in summer they hold at 12 to 39 ft; winter keeps them in 12 to 39 ft. The chart's best answer is Deep basin — deep basin, 33 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.
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 | 12 to 39 ft chart-limited; documented 15 to 45 ft | midday & dawn | Shoreline break (18 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (33 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Shoreline break (18 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 39 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (33 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season cisco (lake herring) use the shallows, holding in 10 to 39 ft. Even in summer they hold at 12 to 39 ft; winter keeps them in 12 to 39 ft. The chart's best answer is Deep basin — deep basin, 33 ft, prime for spring. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.
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 39 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (33 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 39 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (33 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Shoreline break (18 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 39 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (33 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline break (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |
