66-acre lake in Algoma District, Ontario. The lake tops out around 7 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Wenn Lake maps at 66 acres behind 2.6 miles of shoreline. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.9 mi end to end and 0.3 mi across at its widest. It sits in Algoma District. If the bite dies, Wensley Lake is 2 mi to the northeast.
Early season brook trout use the shallows, holding in 1 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 1 to 7 ft. Put Deep basin first on the milk run — a deep basin near 6 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.
