16-acre lake in Sudbury District, Ontario. The lake tops out around 51 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Ivanhoe L. 41 runs 16 acres with 0.9 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. 30% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. You'll find it in Sudbury District. The nearest mapped water is Ivanhoe L. 42, 0 mi to the east.
In spring, splake run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 15 to 51 ft before dropping to 10 to 45 ft for winter. Summer splake concentrate at Break off the point, a prime-rated drop-off around 23 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (13 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 15 to 51 ft | dawn & dusk | Break off the point (23 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
