144-acre lake in Peterborough County, Ontario. The lake tops out around 98 ft. The depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Greens Lake maps at 145 acres behind 5.2 miles of shoreline. That shoreline is heavily fingered (development index 3.1) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 63% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1 mi with a 0.7-mi widest point. Peterborough County claims this one. Its nearest charted neighbour, Picard Lake, is 1 mi to the south.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Break off the point is the standout, a drop-off at roughly 20 ft, rated prime for summer yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

Early season muskellunge use the shallows, holding in 3 to 12 ft. Summer is an 8 to 25 ft game here, winter a 15 to 35 ft one. The chart's best answer is Break off the point — drop-off, 20 ft, prime for fall. Best bite is the evening and early morning. Tie on a double-10 bucktail or a topwater (walk-the-dog / creeper) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (1 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (20 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |

| Winter | 15 to 35 ft | midday | Break off the point (20 ft) | Large rubber, crawled slow |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |

In spring, rock bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 12 to 30 ft for winter. Fall rock bass concentrate at Break off the point, a prime-rated drop-off around 20 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.
