412-acre lake near Québec. The lake tops out around 16 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Lac Joseph runs 412 acres with 7 miles of edge. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 5 to 16 ft, wintering in 2 to 16 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 16 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
