Rating depth structure for burbot.
Recent public catches load as you reach this section.
66-acre lake in Algoma District, Ontario. The lake tops out around 36 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 the Ontario MNRF survey of 2021 (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 67 acres of water rimmed by 1.5 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 18% of the water is 15 ft or less, the band where the food chain lives. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Two Horse Lake, 2 mi to the west.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

In spring, splake run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 11 to 36 ft, and winter fish settle into 8 to 36 ft. Break off the point is the standout, a drop-off at roughly 33 ft, rated prime for summer splake. Time it for early morning and the evening. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
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 (15 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 11 to 36 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Break off the point (33 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait |
| Winter | 8 to 36 ft chart-limited; documented 10 to 45 ft | dawn | Break off the point (33 ft) | Jigging spoon tipped with minnow head, Small white tube |
Spring puts burbot in skinny water — 11 to 36 ft is the zone. Summer fish stay in 11 to 36 ft, and winter fish hold in 9 to 36 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 36 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.

| Winter | 9 to 36 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (36 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
