4,104-acre lake in Sudbury District, Ontario. The lake tops out around 36 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
Frechette Lake maps at 4,134 acres behind 72.9 miles of shoreline, broken up by 22 islands. A development index of 8.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 86% of the surface on the model — that's where the groceries are. End to end it runs roughly 8.4 mi, about 3.5 mi across. It sits in Sudbury District. Its nearest charted neighbour, Klemmer Lake, is 4 mi to the northeast.
Spring puts lake whitefish in skinny water — 11 to 36 ft is the zone. Summer fish stay in 11 to 36 ft, and winter fish hold in 11 to 36 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 31 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 11 to 36 ft | midday & dawn | Break off the point (16 ft) | Small jig + waxworm, Blade bait (small) |

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 4 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 (4 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring northern pike on Frechette 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 4 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.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
