Rating depth structure for lake trout.

89-acre lake in Sudbury District, Ontario. The lake tops out around 66 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The season-by-season read for each species follows, from the map's own numbers.
Little Dennie Lake maps at 90 acres behind 2.8 miles of shoreline. With a 2.1 development index there's bank structure worth casting at, in moderation. About 45% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1 mi long by 0.4 mi wide at the broadest reach. Sudbury District claims this one. Dennie Lake sits 1 mi southeast — the closest neighbouring chart.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 20 to 66 ft in summer and finish the year down in 17 to 66 ft. If you only fish one area, make it Deep basin: a deep basin around 56 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 20 to 66 ft | dawn | Deep basin (56 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (17 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 17 to 66 ft | dawn | Deep basin (56 ft) | White tube jig, Airplane jig |
6 pieces of structure are mapped here — Deep basin, around 56 ft, is the deepest of them.
