65-acre lake in Algoma District, Ontario. The lake tops out around 45 ft. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Slievert Lake maps at 65 acres behind 2.1 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 30% of this chart. Call it 0.8 mi long by 0.2 mi wide at the broadest reach. It sits in Algoma District. Belanger Lake sits 2 mi north — the closest neighbouring chart.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 29 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
