263-acre lake in Sudbury District, Ontario. The lake tops out around 69 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Bull Lake maps at 264 acres behind 5 miles of shoreline. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 32% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.5 mi with a 0.6-mi widest point. It sits in Sudbury District. Seagram Lake sits 2 mi east — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 31 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| 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 | Break off the point (31 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (17 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 21 to 69 ft, and by winter most fish are in 17 to 69 ft. If you only fish one area, make it Deep basin: a deep basin around 59 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 21 to 69 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (17 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 17 to 69 ft | dawn | Deep basin (59 ft) | White tube jig, Airplane jig |
