7-acre lake in Nanaimo Regional District, British Columbia. The lake tops out around 35 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 7 acres of water rimmed by 0.4 miles of bank. Nearly circular (index 1.1), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 29% of this chart, as modeled. You'll find it in Nanaimo Regional District. The nearest mapped water is Lucid Lake, 3 mi to the north.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 9 to 35 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (16 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Inline spinner |
| Winter | 9 to 35 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Marabou jig |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 11 to 35 ft. Main-lake point is the standout, a point at roughly 9 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 11 to 35 ft | midday | Break off the point (16 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 7 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 16 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 35 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
