36-acre lake in Algoma District, Ontario. The lake tops out around 23 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Gravel Lake runs 36 acres with 1.4 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. 54% 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 0.2-mi widest point. The water lies in Algoma District. For a second option, Shadow Lake lies 2 mi northwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 7 to 23 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 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 | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 23 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
