An even grey lid over the water, with dead-still conditions with the barometer flat. Start the search at Lac Gastonguay along windblown banks where food collects. A grinding day likely, with the night worth the effort if any is. Save the long walk for a better forecast. Cooling water has fish active and on the move.

Lac Gastonguay falls in Nord-du-Québec, part of Quebec. Land around it is spruce and muskeg. Around 87 hectares of surface means several distinct areas to work. Shoreline length is close to 6.9 km, and each section fishes a little differently. 68 km away sits Waswanipi, the nearest town. For a city, Saguenay is 344 km off. The nearest boundary is a fair way off.
Without a survey to go on, judge depth from how the bank falls away. On a natural lake the weed line and the shelf beyond it do the work. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for Nord-du-Québec names Arctic charr, brook trout and lake trout. What holds for the county may not hold for this water. Lac Gastonguay responds to conditions more than to tactics.
Typical July readings run about 16°C; by January the average is down near -19°C. The fishing year opens late and shuts early. The lid arrives early and lasts until roughly early May. Average temperatures cross freezing around early May in spring and again near mid November in autumn. May into June fishes hardest, and September gives a second good stretch before the lid returns. Expect Lac Gastonguay to follow that timing.
There is no clear statement anywhere on who can fish it. It formed naturally, so levels move with rainfall rather than with a gate. Nothing formal is recorded here: no ramp, no car park, no marked path. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. A phone call first saves an afternoon. Check whether bait restrictions apply before you buy any. The nearest alternative is Lac Tolstoi, 3.5 km out. Treat access at Lac Gastonguay as something to verify.
