Low, flat cloud sitting over the water, with barely a breath of wind and no real change in pressure. Whatever swims in Lac Perdu should be near points where shallow meets deep. A stay-home graph, with the night as the one excuse to go. Save the long walk for a better forecast. A raw day: short sessions and precise casts pay.

You will find Lac Perdu in Saguenay/Lac-Saint-Jean, Quebec. Everything around it is spruce and muskeg. About 6 hectares of surface, which puts the far bank inside easy sight. Pont Rouge lies 89 km from the water. Sainte-Jeanne-d'Arc lies 91 km off, Dolbeau-Mistassini another 94 km. What else is close: Lac Crassane out at 1.2 km, Lac Nasal lies 1.4 km on, Lac Canardeau out at 1.6 km, Lac Acere lies 1.6 km on and Lac Doigt d'Or out at 1.8 km. No border sits close enough to matter.
No published figure covers depth, so learn it as you fish. The shallow end warms first and pulls fish in ahead of the rest. Still water like this holds fish on the edges rather than out in the open. Fish documented in Saguenay/Lac-Saint-Jean include northern pike, Atlantic salmon, lake whitefish and fallfish. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. At Lac Perdu light and wind decide more than tackle does.
Typical July readings run about 16°C; by January the average is down near -19°C. Cold dominates the calendar on water this far north. 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 strong weeks are the first after break-up and the last before the freeze. Expect Lac Perdu to follow that timing.
There is no clear statement anywhere on who can fish it. There is no recorded infrastructure here; expect to find your own way in. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. Take the rules with you rather than trusting memory. Close seasons apply to some species and not others. Lac Crassane at 1.2 km is the sensible second choice. Nothing here settles the position at Lac Perdu for certain.
