404-acre lake in Algoma District, Ontario. The lake tops out around 112 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Trotter Lake runs 403 acres with 6.4 miles of edge. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. 22% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 1.6 mi end to end and 1.2 mi across at its widest. You'll find it in Algoma District. For a second option, Echo Lake lies 2 mi southeast.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 34 to 112 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 95 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (28 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 34 to 112 ft | dawn | Deep basin (95 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (28 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (50 ft) | White tube jig, Airplane jig |
Spring cisco (lake herring) on Trotter Lake hold shallow, usually 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft. Put Break off the point first on the milk run — a drop-off near 50 ft that grades prime for winter. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (95 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (95 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (50 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
