Rating depth structure for brook trout.

10-acre lake in Algoma District, Ontario. The lake tops out around 26 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.
Drawn out, this is 10 acres of water rimmed by 0.7 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. About 39% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. You'll find it in Algoma District. The nearest mapped water is Saunders Lake, 0 mi to the northeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 8 to 26 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 22 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
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 | 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (12 ft) | Small jigging spoon, Tungsten jig + plastic |
