276-acre lake near Québec. The lake tops out around 85 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 276 acres wrapped in 2.7 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 28% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1 mi end to end and 0.7 mi across at its widest. Antoine-Labelle MRC claims this one. Lac Castor sits 1 mi north — the closest neighbouring chart.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Main-lake point: a point around 10 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.
