60-acre lake in Parry Sound District, Ontario. The lake tops out around 33 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Dump Lake maps at 60 acres behind 2.4 miles of shoreline. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 64% of the surface on the model — that's where the groceries are. Figure 0.8 mi of water from one end to the other, 0.3 mi at the beam. Parry Sound District claims this one. If the bite dies, Fox Lake is 1 mi to the west.
Spring puts lake whitefish in skinny water — 10 to 33 ft is the zone. Summer fish stay in 10 to 33 ft, and winter fish hold in 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 28 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft | midday & dawn | Break off the point (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 10 to 33 ft | dawn | Deep basin (28 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (15 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 10 to 33 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring smallmouth bass on Dump Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 10 to 33 ft. The chart's best answer is Main-lake point — point, 8 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 10 to 33 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
