28-acre lake in Timiskaming District, Ontario. The lake tops out around 33 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. What the data behind the map says about each species, season by season:
Drawn out, this is 28 acres of water rimmed by 1.9 miles of bank. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 56% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. The water lies in Timiskaming District. The nearest mapped water is Flood L., 1 mi to the northeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (28 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (15 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: splake sit in 5 to 25 ft that time of year. Summer pushes them deeper, 10 to 33 ft, and winter fish settle into 7 to 33 ft. The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for splake in summer. Warm-month bites cluster around early morning and the evening. Throw a trolled spoon at the thermocline or a white tube jig (deep) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 10 to 33 ft | dawn & dusk | Break off the point (15 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 9 to 33 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait |
| Winter | 7 to 33 ft | dawn | Break off the point (15 ft) | Jigging spoon tipped with minnow head, Small white tube |
Early season yellow perch 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 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
