578-acre lake in Algoma District, Ontario. The lake tops out around 170 ft. The depth data here comes from the Ontario MNRF survey of 1969, a decades-old survey (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 580 acres, worked by 12.8 miles of shoreline, with 6 islands in the mix. That shoreline is heavily fingered (development index 3.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 20% of this chart. Tip to tip the water measures near 2.5 mi with a 1.1-mi widest point. Algoma District claims this one. If the bite dies, South Lake is 1 mi to the southeast.
Spring brook trout on Summers Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 9 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Secondary point: a point around 9 ft that scores prime in spring. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (165 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Secondary point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (9 ft) | White tube jig, Airplane jig |
7 pieces of structure are mapped here — Deep basin, around 165 ft, is the deepest of them.
