634-acre lake in Alberta. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Johnnys Lake runs 633 acres with 6.6 miles of edge. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory.
Early season yellow perch use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 10 ft, and winter fish settle into 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 10 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring walleye on Johnnys Lake hold shallow, usually 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. Put Break off the point first on the milk run — a drop-off near 5 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | dusk & dawn | Break off the point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 10 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 10 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 10 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for lake whitefish tight to the bank in 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Start at Deep basin. It's a deep basin holding about 10 ft of water and rates prime come summer. Prime time lands in 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 | 3 to 10 ft | midday & dawn | Break off the point (5 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 3 to 10 ft | dawn | Deep basin (10 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 3 to 10 ft | dusk | Break off the point (5 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: burbot in 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. Top water on the chart: Deep basin, a deep basin in the 10-ft range, prime in spring. Time it for after dark and midday. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | night & dusk | Deep basin (10 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |

| Fall | 3 to 10 ft | night & dusk | Deep basin (10 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 3 to 10 ft | night & dusk | Deep basin (10 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |

Anglers target walleye, northern pike, yellow perch, lake whitefish, burbot on Johnnys Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Open the map above to see every rated spot for each species and season.
For yellow perch, 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.
