26-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 26 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 26 acres wrapped in 1.4 miles of bank, with a single island in the mix. With a 2 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 90% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. It sits in Muskoka District Municipality. Its nearest charted neighbour, Tasso Lake, is 1 mi to the west.
Spring brook trout on Doughnut Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 8 to 26 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Deep basin — deep basin, 22 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft | dawn & dusk | Deep basin (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
