4,494-acre lake in Thunder Bay District, Ontario. The lake tops out around 70 ft. The depth data here comes from the Ontario MNRF survey of 1974, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Traced from the shoreline, Garden Lake runs 4,514 acres with 57.1 miles of edge — 99 islands included. That shoreline is heavily fingered (development index 6.1) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 38% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 6 mi with a 2.6-mi widest point. You'll find it in Thunder Bay District. The nearest mapped water is McMullen Lake, 4 mi to the northeast.
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 21 to 70 ft in summer and finish the year down in 25 to 70 ft. If you only fish one area, make it Deep basin: a deep basin around 60 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 | 15 to 45 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 21 to 70 ft | dawn | Deep basin (60 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (6 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (60 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 21 to 70 ft in summer and finish the year down in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 60 ft that scores prime in summer. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (23 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 21 to 70 ft | dawn | Deep basin (60 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (6 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (60 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Garden Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Break off the point — drop-off, 23 ft, prime for fall. Prime time lands in 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 | 4 to 15 ft | dusk & dawn | Rock reef (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (23 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. The chart's best answer is Back-bay flat — weed flat, 3 ft, prime for spring. Best bite is 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 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Back-bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. 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 | Back-bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Weed flat (7 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Weed flat (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Weed flat (7 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: burbot in 25 to 70 ft. The depth story barely changes: 21 to 70 ft through summer, 15 to 60 ft in winter. The spot to know is Deep basin, a deep basin in about 60 ft of water that rates prime for burbot in spring. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (60 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 21 to 70 ft | night & midday | Deep basin (60 ft) | Heavy jig + cut bait |
| Fall | 21 to 70 ft | night & dusk | Deep basin (60 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (60 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
