14-acre lake in Nipissing District, Ontario. The lake tops out around 25 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 14 acres, worked by 0.7 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. About 31% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 0.3 mi. Nipissing District claims this one. If the bite dies, Long L. is 1 mi to the southwest.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 8 to 25 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| 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 | 8 to 25 ft | dawn & dusk | Deep basin (21 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 (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Turtle Lake carries 3 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 21 ft down.
