56-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 28 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 56 acres of water rimmed by 3.7 miles of bank. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 66% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 1 mi with a 0.4-mi widest point. The water lies in Muskoka District Municipality. For a second option, Teapot Lake lies 1 mi north.
Spring cisco (lake herring) on Circular Lake hold shallow, usually 7 to 28 ft. Depth-wise the year is flat: 8 to 28 ft in summer, 8 to 28 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 24 ft, prime for spring. Prime time lands in early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 28 ft | dawn & dusk | Deep basin (24 ft) | Small silver spoon, Tiny swim jig (white) |

Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
