509-acre lake in Haliburton County, Ontario. The lake tops out around 60 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
The drawn water covers 512 acres wrapped in 8.3 miles of bank. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 40% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 3 mi end to end and 1.1 mi across at its widest. It sits in Haliburton County. German Lake sits 1 mi west — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in summer. In summer the feeding windows fall in 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 | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 60 ft that grades prime for summer. 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 | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 18 to 60 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 15 to 60 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
Spring splake on Madawaska Lake hold shallow, usually 5 to 25 ft. By summer they slide out to 25 to 60 ft, and by winter most fish are in 10 to 45 ft. The chart's best answer is Break off the point — drop-off, 10 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Break off the point (10 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (60 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (10 ft) | Jigging spoon tipped with minnow head, Small white tube |
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. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for summer 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 (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring smallmouth bass on Madawaska Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. Put Break off the point first on the milk run — a drop-off near 10 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (10 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 5 to 20 ft, wintering in 12 to 30 ft. Fall rock bass concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around the evening. A ned rig (small) or a marabou jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (2 ft) | 1/16 oz jig + grub, Small inline spinner |
