Rating depth structure for lake trout.

55-acre lake in Algoma District, Ontario. The lake tops out around 27 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 55 acres, worked by 1.7 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. About 54% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. It sits in Algoma District. Harry Lake sits 0 mi south — the closest neighbouring chart.
When the water first warms, lake trout slide up into 7 to 27 ft. There's no big seasonal slide here — summer means 8 to 27 ft, winter 7 to 27 ft. If you only fish one area, make it Deep basin: a deep basin around 23 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 27 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 8 to 27 ft | dawn | Deep basin (23 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 27 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 7 to 27 ft | dawn | Deep basin (23 ft) | White tube jig, Airplane jig |
5 pieces of structure are mapped here — Deep basin, around 23 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Nina Lake specifically, so confirm the current rules before you fish.
