9-acre lake in Sudbury District, Ontario. The lake tops out around 30 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Ivanhoe L. 9 draws 9 acres inside 0.8 miles of shoreline. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. 91% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.3 mi long. You'll find it in Sudbury District. Closest neighbour on DepthScout: Saw Lake, 1 mi east 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: Deep basin, a deep basin in the 29 ft range, prime in summer. 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 (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 6 to 30 ft. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
