214-acre lake near Québec. The lake tops out around 72 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 Rainbow maps at 214 acres behind 3.1 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 45% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.2 mi, about 0.7 mi across. Argenteuil MRC claims this one. Its nearest charted neighbour, Petit lac Rainbow, is 1 mi to the southwest.
