264-acre lake in Sudbury District, Ontario. The lake tops out around 89 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Bowland Lake draws 265 acres inside 7.5 miles of shoreline, broken up by 12 islands. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 38% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.6 mi end to end and 0.9 mi across at its widest. You'll find it in Sudbury District. Closest neighbour on DepthScout: Laundrie Lake, 3 mi north of here.
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 27 to 89 ft; cold water stacks them in 20 to 80 ft. Deep basin is the standout, a deep basin at roughly 86 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (43 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 27 to 89 ft | dawn | Deep basin (86 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (43 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (86 ft) | White tube jig, Airplane jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (43 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
