Rating depth structure for brook trout.
Recent public catches load as you reach this section.
72-acre lake in Hastings County, Ontario. The lake tops out around 50 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a transect sounding survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Aide Lake runs 72 acres with 3.5 miles of edge — 6 islands included. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 79% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.9 mi, about 0.4 mi across. You'll find it in Hastings County. Closest neighbour on DepthScout: Weslemkoon Lake, 6 mi east of here.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (20 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (1 ft) | Tungsten ice jig + plastic, Tiny spoon |
