A grey, even sky over the water, with a whisper of wind from the WNW with the barometer flat. Lac Roy should fish best around the weed line and any gaps in it today. Not a day the forecast likes; the night keeps a flicker of interest. Lower the pace and stay patient. A cold snap day, so work the warmest water you can find.

Lac Roy lies within the bounds of Mauricie, Quebec. Height above sea level is 444 metres. About 5.43 sq km, so local knowledge or a boat saves a lot of walking. Around 25 km of margin, so directions matter more than a general plan. Size puts it in the front rank of our Mauricie list. Nearest town is Chapais, 75 km off. Chibougamau is 94 km and Leblanc 98 km. One jurisdiction covers this water end to end.
Depth is not on record here, which means reading the ground instead. Still water like this holds fish on the edges rather than out in the open. This is a lake, so the margins and the first drop matter most. Reported across Mauricie: northern pike, brook trout, walleye, yellow perch and white sucker. County records show what lives in the area; the local agency holds the water-by-water list. The near bank of Lac Roy is often the one people ignore.
July runs about 16°C on average, January about -19°C. Everything is compressed into the middle of the year. Count on hard cover from midwinter, and open water from early May. The season between ice runs from about early May to mid November. The middle of summer slows a little, with dawn and dusk carrying it. Lac Roy runs to its own calendar within the local pattern.
Public data does not answer the access question here. This is a natural basin, not a dammed one. The map shows no ramp or car park nearby, so this is a walk-in water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Gates get locked out of season on water like this. Where parking is tight, arriving early solves most problems. Lac Cawcot, 2.7 km away, makes the obvious fallback. Rules at Lac Roy are worth checking on the day.
