2,751-acre lake in Algoma District, Ontario. The lake tops out around 120 ft. The depth data here comes from the Ontario MNRF survey of 1966, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 2,764 acres, worked by 27.9 miles of shoreline, broken up by 37 islands. A development index of 3.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 26% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 5.3 mi with a 1.7-mi widest point. Algoma District claims this one. If the bite dies, Strickland Lake is 4 mi to the southeast.
Spring lake trout on Dayohessarah Lake hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 115 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Shoreline point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (115 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (25 ft) | White tube jig, Airplane jig |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 6 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (28 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Offshore hump (25 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (6 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Offshore hump (25 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 40 to 80 ft before dropping to 20 to 60 ft for winter. Winter cisco (lake herring) concentrate at Offshore hump, a prime-rated offshore hump around 25 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Offshore hump (25 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (115 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Rock reef (6 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Offshore hump (25 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Weed flat is the standout, a weed flat at roughly 7 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (7 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

| Winter | 15 to 35 ft | midday & dawn | Offshore hump (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring burbot on Dayohessarah Lake hold shallow, usually 25 to 70 ft. They move out to 50 to 120 ft in summer and finish the year down in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 115 ft that grades prime for summer. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Offshore hump (25 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
