Rating depth structure for brook trout.

203-acre lake in Timiskaming District, Ontario. The lake tops out around 46 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 1979, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
The drawn water covers 204 acres wrapped in 7.3 miles of bank, with 6 islands in the mix. That shoreline is heavily fingered (development index 3.6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 57% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.2 mi, about 0.9 mi across. It sits in Timiskaming District. If the bite dies, Chalice Lake is 3 mi to the north.
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.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Main-lake point. It's a point holding about 1 ft of water and rates prime come spring. Prime time lands in 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 (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (1 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 | Break off the point (1 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 14 to 46 ft, and winter fish settle into 14 to 46 ft. Deep basin is the standout, a deep basin at roughly 46 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon 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 | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 14 to 46 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (46 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (1 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 14 to 46 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (46 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, cisco (lake herring) run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 14 to 46 ft, and winter fish settle into 14 to 46 ft. Deep basin is the standout, a deep basin at roughly 46 ft, rated prime for summer cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic 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 | 10 to 40 ft | dawn & dusk | Deep basin (46 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 14 to 46 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (46 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (1 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 14 to 46 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (46 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
6 pieces of structure are mapped here — Deep basin, around 46 ft, is the deepest of them.

Dee's Lake is about 46 ft (14 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey).
Anglers target brook trout, lake whitefish, cisco (lake herring) on Dee's Lake.
Deep basin is the top-rated area: a deep basin in about 46 ft of water that rates prime for lake whitefish in summer. Scroll up to the map for the complete spot list by 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.
