Rating depth structure for lake trout.

1,481-acre lake in Algoma District, Ontario. The lake tops out around 110 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 1965, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 1,488 acres, worked by 33.8 miles of shoreline — 51 islands included. An index of 6.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 40% of this chart. End to end it runs roughly 3.8 mi, about 2.6 mi across. It sits in Algoma District. Wabigoon Lake sits 2 mi southeast — 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.

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 13 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 (13 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (13 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Mijinemungshing Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 33 to 110 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Deep basin — deep basin, 106 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
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 | Main-lake point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 33 to 110 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (106 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (52 ft) | White tube jig, Airplane jig |
Spring rainbow smelt on Mijinemungshing Lake hold shallow, usually 2 to 20 ft. They move out to 25 to 80 ft in summer and finish the year down in 15 to 60 ft. Put Break off the point first on the milk run — a drop-off near 52 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a tiny vertical jig or a small sabiki-style rig where legal.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 20 ft | night & dusk | Feeding flat (10 ft) | Tiny silver jig, Micro spoon |
| Summer | 25 to 80 ft | dawn & dusk | Break off the point (52 ft) | Tiny vertical jig, Small sabiki-style rig where legal |
| Fall | 18 to 65 ft | dusk & dawn | Break off the point (52 ft) | Micro spoon, Tiny jig |
| Winter | 15 to 60 ft | dusk | Break off the point (52 ft) | Tiny glow jig, Micro jigging spoon |
