Rating depth structure for brook trout.
Recent public catches load as you reach this section.
11-acre lake in Cochrane District, Ontario. The lake tops out around 40 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 1960, a decades-old survey (an MNRF lake survey). What follows comes from the same scoring engine that paints the spots above.
Scaup Lake maps at 11 acres behind 0.9 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 98% of this chart. Call it 0.4 mi long. Cochrane District claims this one. Its nearest charted neighbour, Robin Lake, is 0 mi to the north.
Spring brook trout on Scaup Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 18 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (18 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, splake slide up into 5 to 25 ft. Summer is a 12 to 40 ft game here, winter a 9 to 40 ft one. Start at Deep basin. It's a deep basin holding about 18 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon at the thermocline or a white tube jig (deep) rigged through the warm months.
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 (1 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 12 to 40 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (18 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait |
| Winter | 9 to 40 ft chart-limited; documented 10 to 45 ft | dawn | Deep basin (18 ft) | Jigging spoon tipped with minnow head, Small white tube |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 18 ft.

Deep basin is the top-rated area: a deep basin in about 18 ft of water that rates prime for splake in summer. Every other rated spot, per species and season, is on the map above.
For brook trout, 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.
