128-acre lake in Algoma District, Ontario. The lake tops out around 66 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Pearl Lake draws 129 acres inside 4.9 miles of shoreline, broken up by 2 islands. The 3.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 35% of the surface — that's where the groceries are. Figure 1.5 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Algoma District. For a second option, Highland Lake lies 1 mi south.

In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 20 to 66 ft before dropping to 17 to 66 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 66 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (25 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 20 to 66 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (66 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (25 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 17 to 66 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (66 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring rock bass on Pearl Lake hold shallow, usually 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. Put Break off the point first on the milk run — a drop-off near 13 ft that grades prime for fall. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.
| 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 |
| Summer | 5 to 20 ft | dusk | Break off the point (13 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (13 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (13 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (3 ft) | |
| Winter | 10 to 25 ft | midday | open water |
In spring, burbot run shallow here, mostly 20 to 66 ft. Summer keeps them at 20 to 66 ft, and they winter in 15 to 60 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 66 ft. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 66 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (66 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
