208-acre lake in Algoma District, Ontario. The lake tops out around 115 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 211 acres of water rimmed by 5.3 miles of bank. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. 35% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 1.3 mi long by 0.7 mi wide at the broadest reach. You'll find it in Algoma District. Closest neighbour on DepthScout: Shaule Lake, 2 mi west of here.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, good in spring. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 35 to 115 ft before dropping to 20 to 80 ft for winter. The spot to know is Deep basin, a deep basin in about 98 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.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Spring walleye on Bull 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 Main-lake point — point, 29 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).

The chart's best answer is Shallow 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.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

Summer smallmouth bass concentrate at Main-lake point, a prime-rated point around 29 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.
