In Quebec, Lac Derval belongs to Nord-du-Québec. The water sits 407 metres up. Surface area runs to about 9 hectares — small enough to read in one session. Our Nord-du-Québec list holds plenty of bigger water. The closest town, Chibougamau, is 68 km distant. Further out sit Chapais (87 km) and Mistissini (109 km). This one is safely inside the county line.
Depth went unrecorded, which puts the reading back on you. The productive water is a rod length or two out, not a hundred. Bays and points beat straight shoreline every time on water like this. Reported across Nord-du-Québec: Arctic charr, brook trout, lake trout, lake whitefish and cisco. What holds for the county may not hold for this water. On Lac Derval a short move beats a long cast.
Long-term averages put July at about 16°C and January near -19°C. The fishing year opens late and shuts early. The freeze runs deep into the year, with break-up near early May. On average, early May opens the water and mid November closes it again. Fishing peaks soon after break-up and again before the cold returns. That is the shape of the year on Lac Derval.
Nothing on record says whether the bank is open or closed. Public data shows nothing built here, so treat the whole approach as informal. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Bank access can be seasonal on ground like this. Some stretches are reserved and marked as such on the ground. Lac Lanteuil, 1.8 km away, makes the obvious fallback. For Lac Derval, the notice at the access point is the final word.
