26-acre lake in Parry Sound District, Ontario. The lake tops out around 21 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Muskrat Lake maps at 25 acres behind 1.4 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 65% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. It sits in Parry Sound District. Its nearest charted neighbour, Partridge Lake, is 0 mi to the south.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 6 to 21 ft; cold water stacks them in 6 to 21 ft. Shallow bay flat is the standout, a weed flat at roughly 3 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.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

A micro tube or a sponge spider (fly) covers the summer program.
