33-acre lake near Québec. The lake tops out around 80 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 season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lac Tessie runs 33 acres with 1 miles of edge. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 6% of the surface — that's where the groceries are. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. The water lies in La Vallée-de-la-Gatineau MRC. For a second option, Lac Doig lies 1 mi west.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 11 ft range, good in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
