132-acre lake in Algoma District, Ontario. The lake tops out around 46 ft. The depth data here comes from the Ontario MNRF survey of 2025 (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 132 acres, worked by 4.1 miles of shoreline, broken up by 5 islands. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 59% of the surface — that's where the groceries are. The basin spans about 1.1 mi end to end and 0.4 mi across at its widest. It sits in Algoma District. If the bite dies, Pickard Lake is 1 mi to the southeast.
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 19 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 (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
