20-acre lake in Sudbury District, Ontario. The lake tops out around 37 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. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 20 acres wrapped in 0.9 miles of bank. Nearly circular (index 1.4), so the story is the bottom, not the bank. 34% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.4 mi end to end. It sits in Sudbury District. If the bite dies, Olympic Lake is 1 mi to the east.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Shoreline break. It's a drop-off holding about 17 ft of water and rates prime come summer. Prime time lands in 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 (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (17 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 | Shoreline break (17 ft) | Small jigging spoon, Tungsten jig + plastic |
