18-acre pond in Ontario. The lake tops out around 34 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 18 acres of water rimmed by 1.1 miles of bank. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 24% of this chart, as modeled. End to end it runs roughly 0.3 mi, about 0.2 mi across. The water lies in Brant. Closest neighbour on DepthScout: Lake Hunger, 11 mi south of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 7 to 34 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 34 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 34 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 10 to 34 ft. The spot to know is Main-lake point, a point in about 9 ft of water that rates prime for largemouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (9 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 34 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. As the season builds they drop to 10 to 25 ft, wintering in 10 to 34 ft. Top water on the chart: Deep basin, a deep basin in the 29 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (15 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (15 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 34 ft | midday | Deep basin (29 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring pumpkinseed on Cooley Pond hold shallow, usually 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 6 to 18 ft. The chart's best answer is Break off the point — drop-off, 15 ft, good for winter. Prime time lands in the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | open water | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Break off the point (15 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Break off the point (15 ft) | Tungsten ice jig + plastic, Tiny spoon |
In spring, common carp run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 10 to 30 ft for winter. Winter common carp concentrate at Deep basin, a prime-rated deep basin around 29 ft. Fish it in early morning and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | |
| Summer | 3 to 15 ft | dawn & dusk | open water | |
| Fall | 5 to 18 ft | midday | open water | |
| Winter | 10 to 30 ft | midday | Deep basin (29 ft) |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 29 ft.
