93-acre lake in Algoma District, Ontario. The lake tops out around 66 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Myrtle Lake runs 94 acres with 2.7 miles of edge. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. 44% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 0.8 mi long by 0.4 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Gagnon Lake, 1 mi to the south.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 30 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| 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 (30 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 |
Spring puts splake in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 10 to 45 ft. Summer splake concentrate at Break off the point, a prime-rated drop-off around 30 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (17 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (30 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (30 ft) | Jigging spoon tipped with minnow head, Small white tube |
Spring cisco (lake herring) on Myrtle Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 20 to 66 ft, and by winter most fish are in 20 to 60 ft. The chart's best answer is Deep basin — deep basin, 56 ft, prime for summer. Prime time lands in early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (30 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 20 to 66 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (56 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (30 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (56 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Myrtle Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 56 ft down.

Myrtle Lake is about 66 ft (20 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target brook trout, splake, cisco (lake herring) on Myrtle Lake.
Break off the point is the top-rated area: a drop-off in about 30 ft of water that rates prime for splake in summer. Every other rated spot, per species and season, is on the map above.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
