Rating depth structure for brook trout.
Recent public catches load as you reach this section.
274-acre lake in Algoma District, Ontario. The lake tops out around 20 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 1970, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 276 acres wrapped in 2.9 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 51% of this chart. Figure 1.1 mi of water from one end to the other, 0.6 mi at the beam. Algoma District claims this one. West Joco Lake sits 2 mi south — the closest neighbouring chart.
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.

Spring brook trout on Queminico Lake hold shallow, usually 2 to 15 ft. They move out to 6 to 20 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 20 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.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: cisco (lake herring) in 5 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 6 to 20 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (20 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 6 to 20 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (20 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 4 to 20 ft chart-limited; documented 5 to 25 ft | dusk & dawn | Break off the point (18 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 6 to 20 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (20 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, rainbow smelt slide up into 2 to 20 ft. There's no big seasonal slide here — summer means 6 to 20 ft, winter 5 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a tiny vertical jig or a small sabiki-style rig where legal rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |

| Winter | 5 to 20 ft chart-limited; documented 15 to 60 ft | dusk | Deep basin (20 ft) | Tiny glow jig, Micro jigging spoon |
The spring pattern is a shallow one: lake whitefish in 6 to 20 ft. The depth story barely changes: 6 to 20 ft through summer, 6 to 20 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 20 ft.

Queminico Lake is about 20 ft (6 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey).
Anglers target brook trout, cisco (lake herring), rainbow smelt, lake whitefish on Queminico Lake.
Deep basin is the top-rated area: a deep basin in about 20 ft of water that rates prime for cisco (lake herring) in spring. Open the map above to see every rated spot for each species and season.
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.
