135-acre lake in Nipissing District, Ontario. The lake tops out around 37 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 137 acres, worked by 2.6 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 55% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.8 mi long by 0.4 mi wide at the broadest reach. It sits in Nipissing District. North River Lake sits 1 mi north — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 17 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (17 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (4 ft) | |

Early season burbot use the shallows, holding in 11 to 37 ft. Even in summer they hold at 11 to 37 ft; winter keeps them in 9 to 37 ft. Put Deep basin first on the milk run — a deep basin near 31 ft that grades prime for spring. In summer the feeding windows fall in after dark and midday. Tie on a heavy jig + cut bait and you're in the game.

| Spring | 11 to 37 ft | night & dusk | Deep basin (31 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 11 to 37 ft | night & midday | Deep basin (31 ft) | Heavy jig + cut bait |
