9-acre lake in Sudbury District, Ontario. The lake tops out around 22 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. Here's the year, species by species, as the scoring engine sees it.
Soucie Lake maps at 9 acres behind 0.6 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 40% of this chart, as modeled. It sits in Sudbury District. Its nearest charted neighbour, Mousseau Lake, is 2 mi to the southeast.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 7 to 22 ft, then a winter hold in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin 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.
