413-acre lake in British Columbia. The lake tops out around 30 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
Marian Lake maps at 412 acres behind 4.9 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Roughly 75% of the water is 15 ft or less as modeled, the band where the food chain lives.
When the water first warms, coho salmon slide up into 3 to 25 ft. Summer is a 9 to 30 ft game here, winter a 9 to 30 ft one. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a dodger + fly or a medium spoon above the thermocline rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 9 to 30 ft | dawn & dusk | Deep basin (26 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 6 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 9 to 30 ft | midday | Deep basin (26 ft) | Small spoon, slow troll |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 9 to 30 ft; cold water stacks them in 8 to 30 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or a inline spinner covers the summer program.
| 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 | 9 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 8 to 30 ft | dawn | Deep basin (26 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 6 to 30 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| 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 | 8 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft | dawn | Deep basin (26 ft) | Jigging spoon, Tube jig (white) |
