1,066-acre lake in Thunder Bay District, Ontario. The lake tops out around 100 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 season-by-season read for each species follows, from the map's own numbers.
On the chart, Disraeli Lake draws 1,069 acres inside 9 miles of shoreline. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. 59% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 2.7 mi of water from one end to the other, 1.4 mi at the beam. You'll find it in Thunder Bay District. For a second option, Little Sturge Lake lies 6 mi northeast.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 30 to 100 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 100 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
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 | Break off the point (27 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 30 to 100 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (100 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (27 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (27 ft) | White tube jig, Airplane jig |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft. If you only fish one area, make it Break off the point: a drop-off around 27 ft that scores prime in winter. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (27 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | open water | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (27 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (27 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Disraeli Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Break off the point — drop-off, 27 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (27 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (27 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (27 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. The chart's best answer is Back-bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (27 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (27 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (27 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. Winter smallmouth bass concentrate at Break off the point, a prime-rated drop-off around 27 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (4 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (27 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (27 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (27 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: burbot in 25 to 70 ft. Midsummer fish sit out in 30 to 100 ft before dropping to 15 to 60 ft for winter. The spot to know is Deep basin, a deep basin in about 100 ft of water that rates prime for burbot in summer. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
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 | 25 to 70 ft | night & dusk | Break off the point (27 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |

| Winter | 15 to 60 ft | night & dusk | Break off the point (27 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
