442-acre lake in Nipissing District, Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 1973, a decades-old survey (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 444 acres of water rimmed by 6.5 miles of bank, with a single island in the mix. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 60% of the surface — that's where the groceries are. Tip to tip the water measures near 1.7 mi with a 1-mi widest point. You'll find it in Nipissing District. Closest neighbour on DepthScout: Serene Lake, 2 mi northeast of here.
When the water first warms, cisco (lake herring) slide up into 8 to 30 ft. There's no big seasonal slide here — summer means 9 to 30 ft, winter 9 to 30 ft. Start at Deep basin. It's a deep basin holding about 30 ft of water and rates prime come spring. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 9 to 30 ft | dawn | Deep basin (30 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (29 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 9 to 30 ft | dawn | Deep basin (30 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring yellow perch on Sucker Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 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. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| 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 | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |
