59-acre lake in Sudbury District, Ontario. The lake tops out around 60 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Spring Lake runs 58 acres with 1.5 miles of edge. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. 15% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 0.4 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Sudbury District. The nearest mapped water is Wood Lake, 1 mi to the west.
Start shallow in spring: splake sit in 5 to 25 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 45 ft. Top water on the chart: Break off the point, a drop-off in the 27 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon at the thermocline or a white tube jig (deep) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (15 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (27 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (27 ft) | Jigging spoon tipped with minnow head, Small white tube |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 18 to 60 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 51 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 (51 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 18 to 60 ft | dawn | Deep basin (51 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (27 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (51 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
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 Break off the point — drop-off, 27 ft, prime for summer. 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 | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. If you only fish one area, make it Main-lake point: a point around 15 ft that scores prime in summer. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (15 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (15 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (27 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores prime in spring. Best bite is the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (6 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
