220-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 18 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. What the data behind the map says about each species, season by season:
Drawn out, this is 220 acres of water rimmed by 2.5 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 84% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 0.8 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Bulkley-Nechako Regional District. The nearest mapped water is Aldrich Lake, 3 mi to the east.
Spring cutthroat trout on Dennis Lake hold shallow, usually 3 to 15 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Break off the point — drop-off, 8 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a trolled spoon (small) or an inline spinner.
| 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 | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 18 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Marabou jig |
Start shallow in spring: rainbow trout sit in 5 to 18 ft that time of year. They don't go far with the seasons — 5 to 18 ft covers summer, 4 to 18 ft covers winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for lake whitefish tight to the bank in 5 to 18 ft. Through summer count on 5 to 18 ft; the winter hold is 5 to 18 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 18 ft | midday & dawn | Break off the point (8 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 18 ft | dawn | Deep basin (15 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 18 ft | dusk | Break off the point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (15 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The chart marks 6 structure features on Dennis Lake; the deepest is Deep basin at about 15 ft.
