Rating depth structure for lake whitefish.
Recent public catches load as you reach this section.
944-acre lake near Marlboro. The lake tops out around 15 ft. The depth chart comes from Alberta Geological Survey bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Fickle Lake maps at 942 acres behind 6.9 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The basin spans about 2.2 mi end to end and 1.4 mi across at its widest. It sits in Division No. 14. Its nearest charted neighbour, Black Mud Lake, is 8 mi to the north.
Start shallow in spring: lake whitefish sit in 5 to 15 ft that time of year. They don't go far with the seasons — 5 to 15 ft covers summer, 5 to 15 ft covers winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
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 | 5 to 15 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (10 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 15 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (15 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 15 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (10 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 15 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (15 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 15 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (10 ft) | Tip-ups, Large jigging spoon |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer keeps them at 5 to 15 ft, and they winter in 5 to 15 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 10 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 15 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 15 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 15 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

Fickle Lake is about 15 ft (5 m) deep at its deepest point. The depth chart comes from Alberta Geological Survey bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target lake whitefish, northern pike, walleye, yellow perch on Fickle Lake.
Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for lake whitefish in summer. The interactive chart above rates every spot for each species and season.
For lake whitefish, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
