1,102-acre lake in Algoma District, Ontario. The lake tops out around 184 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
Wart Lake maps at 1,104 acres behind 24.3 miles of shoreline, with 6 islands in the mix. A development index of 5.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 27% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 2.5 mi long by 2.5 mi wide at the broadest reach. Algoma District claims this one. If the bite dies, Spider L. is 2 mi to the southeast.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 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 | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Main-lake point — point, 46 ft, prime for fall. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (46 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (156 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (46 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (156 ft) | White tube jig, Airplane jig |
Wart Lake carries 5 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 156 ft down.
