7-acre lake in Sudbury District, Ontario. The lake tops out around 55 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Spring L. draws 7 acres inside 0.5 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 16% of the surface on the model — that's where the groceries are. The water lies in Sudbury District. Closest neighbour on DepthScout: Foleyet L. 4, 0 mi southwest of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Shoreline break, a drop-off in the 25 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 17 to 55 ft, and by winter most fish are in 17 to 55 ft. If you only fish one area, make it Deep basin: a deep basin around 47 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shoreline break (25 ft) | Small jig + waxworm, Blade bait (small) |

When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 17 to 55 ft, and by winter most fish are in 17 to 55 ft. If you only fish one area, make it Deep basin: a deep basin around 47 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (47 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 17 to 55 ft | dawn | Deep basin (47 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Shoreline break (25 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 17 to 55 ft | dawn | Deep basin (47 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring yellow perch on Spring L. hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shoreline break — drop-off, 25 ft, prime for summer. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| 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 | Shoreline break (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Shoreline break (25 ft) | Jigging spoon (small), Perch rig / spreader |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated feeding flat around 6 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
