130-acre lake near Québec. The lake tops out around 59 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. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Lac des Mauves draws 130 acres inside 1.7 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 28% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.6 mi, about 0.4 mi across. You'll find it in Matawinie MRC. Closest neighbour on DepthScout: Lac Régis, 1 mi southeast of here.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated good for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
