638-acre lake in Nipissing District, Ontario. The lake tops out around 103 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 636 acres wrapped in 10.2 miles of bank. A development index of 2.9 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 17% of the surface on the model — that's where the groceries are. Figure 3.4 mi of water from one end to the other, 0.9 mi at the beam. Nipissing District claims this one. Loxley Lake sits 1 mi northeast — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Shallow bay flat. It's a feeding flat holding about 6 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 31 to 103 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 88 ft, prime for summer. Best bite is 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 (26 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 31 to 103 ft | dawn | Deep basin (88 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (26 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (46 ft) | White tube jig, Airplane jig |
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Deep basin is the standout, a deep basin at roughly 88 ft, rated prime for summer cisco (lake herring). Plan around early morning in the warm months. 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 | Deep basin (88 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (88 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (46 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring brown bullhead on Little Cauchon Lake hold shallow, usually 2 to 8 ft. They move out to 3 to 12 ft in summer and finish the year down in 10 to 25 ft. Put Shallow bay flat first on the milk run — a feeding flat near 6 ft that grades prime for summer. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (88 ft) |
Early season burbot use the shallows, holding in 25 to 70 ft. Summer is a 31 to 103 ft game here, winter a 15 to 60 ft one. The chart's best answer is Deep basin — deep basin, 88 ft, prime for summer. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (46 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 31 to 103 ft | night & midday | Deep basin (88 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (88 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (46 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
