Rating depth structure for lake trout.

503-acre lake in Algoma District, Ontario. The lake tops out around 102 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 509 acres, worked by 11.9 miles of shoreline, with 2 islands in the mix. The 3.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 51% of this chart, as modeled. Call it 1.7 mi long by 1.2 mi wide at the broadest reach. It sits in Algoma District. If the bite dies, Patterson Lake is 6 mi to the southwest.
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 31 to 102 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 87 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 | 10 to 40 ft | dawn & dusk | Main-lake point (26 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 31 to 102 ft | dawn | Deep basin (87 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (26 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (46 ft) | White tube jig, Airplane jig |
