332-acre lake near Québec. The lake tops out around 13 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.
Traced from the shoreline, Lac Waterloo runs 332 acres with 3 miles of edge. 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. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 1 mi end to end and 0.7 mi across at its widest. The water lies in La Haute-Yamaska MRC. The nearest mapped water is Lac Brome, 6 mi to the south.

The spring pattern is a shallow one: rainbow trout in 3 to 13 ft. The depth story barely changes: 3 to 13 ft through summer, 3 to 13 ft in winter. The spot to know is Break off the point, a drop-off in about 12 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
