Low, flat cloud sitting over the water, with a mirror surface most of the day and pressure sitting still. Start the search at Lac du Sphinx along the first drop-off and weed lines. If you must go, go in the night. One good spot fished well beats five fished quickly. Cooler water spreads fish back across the shallows.

Lac du Sphinx is listed under Quebec. Beyond the shoreline you have mixed forest. It covers about 6 hectares, so this is small water you can walk round in under an hour. The nearest town is Deep River, 51 km away. Mattawa is 53 km away, with Chalk River at 60 km. Neighbouring water: Lac de l'Anis sits 1.6 km out, Lac Wilson out at 2.5 km, Lac du Pyrale sits 3 km out, Lac du Foin out at 3.3 km and Lac de la Chevre sits 3.3 km out. It lies deep inside the county rather than near an edge.
Depth is unmeasured here, so let the shoreline guide you. Look for the band where the shallows give up and the bottom falls away. Bays and points beat straight shoreline every time on water like this. On Lac du Sphinx the first feature you find is usually worth a session. Rocky edges hold food that silt bottoms do not.
Climate normals give 18°C for July and -14°C for January. Seasons are distinct, and each one fishes differently. Ice-out usually falls in late April, and the weeks after it fish hardest. On the long-run averages the water opens up around late April and starts locking again about late November. The middle of summer slows a little, with dawn and dusk carrying it. At Lac du Sphinx the season follows that pattern closely.
Nothing we hold confirms whether access is permitted. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Rules for this water may differ from the county norm. Some ground is open by custom rather than by right, so tread carefully. Failing this one, try Lac de l'Anis, 1.6 km away. Ask locally about Lac du Sphinx if anything is unclear.
