66-acre lake in Haliburton County, Ontario. The lake tops out around 92 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Delphis Lake draws 66 acres inside 2.3 miles of shoreline, broken up by 2 islands. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. About 17% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.8 mi long by 0.3 mi wide at the broadest reach. You'll find it in Haliburton County. For a second option, Moore Lake lies 2 mi southeast.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 28 to 92 ft; cold water stacks them in 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 92 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 (12 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 28 to 92 ft | dawn | Deep basin (92 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (12 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (18 ft) | White tube jig, Airplane jig |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, prime for spring. Best bite is the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (6 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
