2,540-acre lake in Algoma District, Ontario. The lake tops out around 380 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Ten Mile Lake runs 2,551 acres with 32.7 miles of edge, with 22 islands in the mix. An index of 4.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 9% of the surface — that's where the groceries are. Tip to tip the water measures near 5.2 mi with a 2.4-mi widest point. You'll find it in Algoma District. The nearest mapped water is Hyphen Lake, 1 mi to the north.
The spring pattern is a shallow one: lake trout in 10 to 40 ft. Midsummer fish sit out in 50 to 120 ft before dropping to 20 to 80 ft for winter. The spot to know is Rock reef, a rock pile in about 8 ft of water that rates prime for lake trout in fall. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Break off the point (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Rock reef (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (59 ft) | White tube jig, Airplane jig |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. If you only fish one area, make it Rock reef: a rock pile around 8 ft that scores prime in spring. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Rock reef (8 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Rock reef (8 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Rock reef (8 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Rock reef (8 ft) | Tungsten jig + plastic, Small spoon + spike |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 6 ft range, prime in summer. Fish it in after dark and the evening and you'll meet the bite.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (359 ft) |
The spring pattern is a shallow one: burbot in 25 to 70 ft. Midsummer fish sit out in 50 to 120 ft before dropping to 15 to 60 ft for winter. The spot to know is Offshore hump, an offshore hump in about 13 ft of water that rates prime for burbot in winter. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (59 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Break off the point (59 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (59 ft) | Glow spoon + minnow head, Blade bait (slow) |
