435-acre lake in Algoma District, Ontario. The lake tops out around 72 ft. The depth data here comes from the Ontario MNRF survey of 1964, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 437 acres of water rimmed by 7.9 miles of bank, with 2 islands in the mix. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 32% of the surface — that's where the groceries are. The basin spans about 2.4 mi end to end and 0.7 mi across at its widest. You'll find it in Algoma District. Closest neighbour on DepthScout: Jobammageeshig Lake, 1 mi northwest of here.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 14 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (14 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 22 to 72 ft before dropping to 18 to 72 ft for winter. The spot to know is Deep basin, a deep basin in about 72 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 22 to 72 ft | dawn | Deep basin (72 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (14 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 72 ft | dawn | Deep basin (72 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 22 to 72 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 72 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 | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 22 to 72 ft | dawn | Deep basin (72 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (14 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (72 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 22 to 72 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 72 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 | Deep basin (72 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 22 to 72 ft | dawn | Deep basin (72 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |

| Winter | 20 to 60 ft | dawn | Deep basin (72 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Chub 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 Main-lake point — point, 14 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 | Main-lake point (14 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (14 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (14 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (72 ft) | Jigging spoon + minnow head, Rattle bait |
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 Shallow bay flat, a prime-rated weed flat around 2 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 | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
