128-acre lake in Haliburton County, Ontario. The lake tops out around 105 ft. The depth data here comes from the Ontario MNRF survey of 1983 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Slipper Lake runs 128 acres with 2.7 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. About 19% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.1 mi long by 0.4 mi wide at the broadest reach. You'll find it in Haliburton County. The nearest mapped water is Stocking Lake, 1 mi to the southeast.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 32 to 105 ft; cold water stacks them in 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 105 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| 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 | 32 to 105 ft | dawn | Deep basin (105 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (34 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (56 ft) | White tube jig, Airplane jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 4 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (105 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (105 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (105 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. Summer brown bullhead concentrate at Shallow bay flat, a prime-rated feeding flat around 4 ft. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (4 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (105 ft) |
