110-acre lake in Nipissing District, Ontario. The lake tops out around 42 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Barmac Lake maps at 109 acres behind 1.8 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 40% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. Nipissing District claims this one. Its nearest charted neighbour, Liberty Lake, is 2 mi to the east.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 13 to 42 ft game here, winter an 11 to 42 ft one. The chart's best answer is Deep basin — deep basin, 36 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 13 to 42 ft | dawn | Deep basin (36 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 42 ft | dusk & dawn | Main-lake point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 11 to 42 ft | dawn | Deep basin (36 ft) | White tube jig, Airplane jig |
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 13 to 42 ft; cold water stacks them in 13 to 42 ft. Deep basin is the standout, a deep basin at roughly 36 ft, rated prime for spring cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 5 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
