370-acre lake in Lennox and Addington County, Ontario. The lake tops out around 100 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Trout Lake runs 372 acres with 5.5 miles of edge, with 6 islands in the mix. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. The shallow band under 15 ft claims about 23% of the surface — that's where the groceries are. End to end it runs roughly 1.5 mi, about 0.7 mi across. You'll find it in Lennox and Addington County. The nearest mapped water is Spring Lake, 2 mi to the west.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 30 to 100 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 100 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| 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 | 30 to 100 ft | dawn | Deep basin (100 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (11 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (57 ft) | White tube jig, Airplane jig |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Back-bay flat (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (100 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (100 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 20 to 45 ft for winter. The spot to know is Main-lake point, a point in about 11 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (11 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (11 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (11 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (57 ft) | Blade bait, Hair jig |
Spring rock bass on Trout Lake hold shallow, usually 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. Put Main-lake point first on the milk run — a point near 11 ft that grades prime for summer. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (11 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (11 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (11 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (100 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring pumpkinseed on Trout Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
