9-acre lake in Sudbury District, Ontario. The lake tops out around 68 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 9 acres wrapped in 0.5 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 18% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Sudbury District claims this one. Its nearest charted neighbour, Cabot L. 4, is 2 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Shoreline break: a drop-off around 31 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| 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 (31 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 |
3 pieces of structure are mapped here — Deep basin, around 58 ft, is the deepest of them.
