132-acre lake in Timiskaming District, Ontario. The lake tops out around 34 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. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 132 acres, worked by 3.2 miles of shoreline. A middling shoreline index (2) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 1 mi end to end and 0.5 mi across at its widest. Timiskaming District claims this one. Its nearest charted neighbour, Logan Lake, is 1 mi to the northeast.
Early season splake use the shallows, holding in 5 to 25 ft. Summer is a 10 to 34 ft game here, winter an 8 to 34 ft one. The chart's best answer is Deep basin — deep basin, 23 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon at the thermocline or a white tube jig (deep) and you're in the game.
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 | 5 to 25 ft | dawn & dusk | Main-lake point (2 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 10 to 34 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (23 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 34 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (2 ft) | Casting spoon, Jerkbait |
| Winter | 8 to 34 ft chart-limited; documented 10 to 45 ft | dawn | Deep basin (23 ft) | Jigging spoon tipped with minnow head, Small white tube |
In spring, cisco (lake herring) run shallow here, mostly 9 to 34 ft. Summer keeps them at 10 to 34 ft, and they winter in 10 to 34 ft. Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 23 ft. Fish it in early morning and you'll meet the bite. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 34 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (23 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 10 to 34 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (23 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (4 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 10 to 34 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (23 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 10 to 34 ft. Deep basin is the standout, a deep basin at roughly 23 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 34 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 34 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 10 to 34 ft. Put Break off the point first on the milk run — a drop-off near 4 ft that grades good for winter. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

Margueratt Lake is about 34 ft (10 m) deep at its deepest point. 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.
Anglers target splake, cisco (lake herring), yellow perch, smallmouth bass on Margueratt Lake.
Deep basin is the top-rated area: a deep basin in about 23 ft of water that rates prime for cisco (lake herring) in spring. The map above holds the full rated-spot list for every species and season.
For splake, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
