1,774-acre lake near Québec. The lake tops out around 195 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's the year, species by species, as the scoring engine sees it.
Lac Cayamant maps at 1,774 acres behind 13.3 miles of shoreline. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 24% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 5.2 mi end to end and 1.5 mi across at its widest. La Vallée-de-la-Gatineau MRC claims this one. Lac Profond sits 9 mi northeast — the closest neighbouring chart.
