30-acre lake in Nanaimo Regional District, British Columbia. The lake tops out around 23 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 30 acres wrapped in 1 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 73% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. Nanaimo Regional District claims this one. If the bite dies, Long Lake is 1 mi to the north.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 6 to 23 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for summer cutthroat trout. Time it for early morning and the evening. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 7 to 23 ft | dawn & dusk | Break off the point (10 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 6 to 23 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| 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 |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 7 to 23 ft, and by winter most fish are in 7 to 23 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 7 to 23 ft | dawn & dusk | Break off the point (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 23 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 7 to 23 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |
Spring rainbow trout on Diver Lake hold shallow, usually 5 to 20 ft. They move out to 6 to 23 ft in summer and finish the year down in 5 to 23 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 23 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 23 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |
