4,050-acre lake in Peterborough County, Ontario. The lake tops out around 150 ft. The depth data here comes from the Ontario MNRF survey of 1961, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The outline encloses 4,069 acres, worked by 53.2 miles of shoreline, with 33 islands in the mix. That shoreline is heavily fingered (development index 5.9) — bays, points and pockets everywhere, which multiplies the fishable edge. About 22% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 5.5 mi long by 4.5 mi wide at the broadest reach. It sits in Peterborough County. If the bite dies, Lasswade Lake is 3 mi to the south.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 34 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (34 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (146 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (5 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Sharp break (32 ft) | White tube jig, Airplane jig |
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 40 to 80 ft, wintering in 20 to 60 ft. Fall cisco (lake herring) concentrate at Rock reef, a prime-rated rock pile around 5 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (11 ft) | Small silver spoon, Tiny swim jig (white) |

| Winter | 20 to 60 ft | dawn | Sharp break (32 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
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 |

| Fall | 12 to 35 ft | midday | Sharp break (32 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Back-bay flat (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Chandos 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.
