11-acre lake near Québec. The lake tops out around 15 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. Species by species, here's what the data says the year looks like.
Lac Montagnac maps at 11 acres behind 0.5 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Matawinie MRC claims this one. Lac Odelin sits 2 mi east — the closest neighbouring chart.

When the water first warms, brook trout slide up into 2 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 2 to 15 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. They don't go far with the seasons — 5 to 15 ft covers summer, 5 to 15 ft covers winter.

Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
