Low, flat cloud sitting over the water, with a mirror surface most of the day and pressure sitting still. Fish at Lac Rainbow should hold close to reed fringes and open pockets. Make the night the heart of the trip. Fish tidy and take what the day gives. Falling temperatures are switching fish back on.

Lac Rainbow lies within the bounds of Mauricie, Quebec. The surface lies 421 metres up. It measures about 16 hectares, which is a comfortable size for bank fishing. Around 2.5 km of margin, front to back. The nearest town is Leblanc, 47 km away. Trois-Rivières sits 235 km out, and it is the nearest city worth the name. No county line comes close, which keeps the paperwork simple.
We hold no depth figure for this one. Look for the band where the shallows give up and the bottom falls away. On a natural lake the weed line and the shelf beyond it do the work. Fish documented in Mauricie include northern pike, brook trout, walleye and yellow perch. Species recorded across the county may be limited to a few waters. On Lac Rainbow that means starting tight and working out.
The range across the year is -17°C to 16°C. A short, intense season is the rule this far north. The open season starts with the thaw, near enough early May. Averages place the thaw at early May and the freeze at mid November. The middle of summer slows a little, with dawn and dusk carrying it. That is the shape of the year on Lac Rainbow.
We hold no note on access for this one. Records list it as a natural water body rather than an impoundment. There is a jetty 840 m off, worth knowing on a busy day. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Local rules can differ across the county line, so check where you stand. Close seasons apply to some species and not others. If the gate is shut, Lac Beaver at 0.9 km is the nearest alternative. What applies at Lac Rainbow may have changed since it was mapped.
