16-acre lake in Sudbury District, Ontario. The lake tops out around 72 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 15 acres wrapped in 0.6 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. About 11% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Sudbury District claims this one. If the bite dies, Suzuki L. is 0 mi to the southeast.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Shoreline break — drop-off, 32 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shoreline break (32 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline break (32 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Shoreline break (32 ft) | Jigging spoon, Tube jig (white) |
