41-acre lake near Québec. The lake tops out around 50 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 41 acres wrapped in 1.1 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 55% of the water is 15 ft or less, the band where the food chain lives. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. La Vallée-de-la-Gatineau MRC claims this one. Lac Ovila sits 0 mi west — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Shallow bay flat — weed flat, 4 ft, good for spring. Best bite is 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.
