141-acre lake in Sudbury District, Ontario. The lake tops out around 44 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What follows comes from the same scoring engine that paints the spots above.
Westmeath Lake maps at 141 acres behind 3.6 miles of shoreline. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 65% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 1 mi with a 0.5-mi widest point. It sits in Sudbury District. Its nearest charted neighbour, Gullystone Lake, is 2 mi to the north.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (37 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (37 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Westmeath Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
