Rating depth structure for brook trout.

7-acre lake in Cochrane District, Ontario. The lake tops out around 20 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Grebe Lake runs 7 acres with 0.6 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. About 83% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.3 mi end to end. You'll find it in Cochrane District. For a second option, Robin Lake lies 1 mi south.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 17 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
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 | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (17 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 | Deep basin (17 ft) | Small jigging spoon, Tungsten jig + plastic |
