13,978-acre lake near Ross Haven. The lake tops out around 30 ft. The depth chart comes from Alberta Geological Survey bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 13,947 acres, worked by 48 miles of shoreline, with 6 islands in the mix. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 49% of this chart. Figure 10.3 mi of water from one end to the other, 5.2 mi at the beam. It sits in Division No. 13. If the bite dies, Birch Lake is 7 mi to the northwest.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Gravel shoal 1. It's a gravel shoal holding about 4 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Gravel shoal 1 (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Gravel shoal 1 (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Gravel shoal 1 (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring burbot on Lac Ste. Anne hold shallow, usually 9 to 30 ft. Depth-wise the year is flat: 9 to 30 ft in summer, 8 to 30 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 30 ft, prime for spring. Prime time lands in after dark and midday. The summer box starts with a heavy jig + cut bait.
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 | 9 to 30 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (30 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 9 to 30 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (30 ft) | Heavy jig + cut bait |
| Fall | 9 to 30 ft chart-limited; documented 30 to 80 ft | night & dusk | Deep basin (30 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 30 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (30 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
In spring, lake whitefish run shallow here, mostly 9 to 30 ft. Summer keeps them at 9 to 30 ft, and they winter in 9 to 30 ft. Deep basin is the standout, a deep basin at roughly 30 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft chart-limited; documented 15 to 45 ft | midday & dawn | Sharp break (11 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (30 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Gravel shoal 1 (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 9 to 30 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (30 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Weed flat 2 — weed flat, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Weed flat 2 (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Sharp break (11 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat 2 (5 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Gravel shoal 1, a gravel shoal in about 4 ft of water that rates prime for walleye in spring. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal 1 (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Sharp break (11 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft chart-limited; documented 12 to 40 ft | dusk & night | Sharp break (11 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (30 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. Spring yellow perch concentrate at Weed flat 2, a prime-rated weed flat around 5 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
