Poor visibility with fog on the water, with a busy SSW wind on the open water and pressure sitting still. The productive water at Lac du Mortier will be around the margins and the shelf beyond them. Everything points to the night. Take the steady approach over the searching one. The autumn feed-up is on; baitfish areas are the key.

Lac du Mortier is one of the Saguenay/Lac-Saint-Jean waters in Quebec. Height above sea level is 547 metres. Surface area is around 20 hectares, which gives you real water without needing a boat. There is roughly 3.4 km of shoreline here, which is a short walk end to end. It is high ground by Quebec standards. 45 km away sits Saint-Félicien, the nearest town. Normandin is 48 km away, with Saint-Prime at 52 km. No county line comes close, which keeps the paperwork simple.
Depth went unrecorded, which puts the reading back on you. Still water like this holds fish on the edges rather than out in the open. Weed, then depth: that is the order to fish a water of this kind. Public occurrence data for Saguenay/Lac-Saint-Jean names northern pike, Atlantic salmon and lake whitefish. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Lac du Mortier responds to conditions more than to tactics.
The range across the year is -18°C to 16°C. Little of the calendar is open water, so timing counts for everything. Firm cover through the cold months, then open water from early May. Break-up sits around early May on average, with the water closing again about mid November. The weeks after the thaw and the ones before the freeze are the strongest. On Lac du Mortier the same rules apply, with local timing.
Who may fish here is not settled in anything we hold. Records list it as a natural water body rather than an impoundment. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. For the pike, wire up and throw larger lures along the weed edges. Rules for this water may differ from the county norm. Check whether bait restrictions apply before you buy any. Lac Rex, 1.4 km away, makes the obvious fallback. Treat access at Lac du Mortier as something to verify.
