Low, flat cloud sitting over the water, with a busy S wind on the open water and the barometer holding steady. Start the search at Lac Witherbee along points where shallow meets deep. A long productive spell runs night into morning. A careful, quiet approach will out-fish a busy one. The autumn feed-up is on; baitfish areas are the key.

Mauricie in Quebec is where Lac Witherbee sits. It sits at 426 metres above sea level. Roughly 35 hectares: a morning covers one end, an afternoon the other. Roughly 3.8 km of bank means you can walk to a fresh area when one goes quiet. It is among the larger waters listed here for Mauricie. La Tuque lies 60 km from the water. It is 109 km to Saguenay, the nearest city. It lies deep inside the county rather than near an edge.
No chart reached our records; the first cast is your sounding. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Across Mauricie, recorded fish include northern pike, brook trout, walleye, yellow perch and white sucker. It is the county picture; the agency list is water-specific. Anyone new to Lac Witherbee should walk it once before setting up.
Between January at about -16°C and July at about 17°C, the water has a wide range to work through. Ice holds for a long stretch, so the open weeks matter more here than further south. Look for the thaw near early May; the fishing lifts straight after. From about early May to around mid November, expect open water on the long-run figures. The first weeks of open water and the last are the ones to plan for. Lac Witherbee runs to its own calendar within the local pattern.
Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Rules for this water may differ from the county norm. Where the way in crosses private ground, ask first. Lac Jacqueline at 0.6 km is the sensible second choice. What applies at Lac Witherbee may have changed since it was mapped.
