Fresh rain topping the water up today, with hardly a ripple anywhere and pressure sitting still. Activity on Lac Therrien should centre on the seam between weed and open water. A grinding day likely, with the night worth the effort if any is. Save the long walk for a better forecast. The pre-winter feed makes autumn days generous.

This water sits in Côte-Nord, Quebec. Elevation runs to 448 metres. A splashy cast here empties the swim; a quiet one owns it. Most waters listed here for Côte-Nord are larger. You are 49 km from Forestville. The nearest city of size is Saguenay, 141 km away. In the same area: Lac Piche at 1.8 km, Lac Nicole out at 2 km, Petit lac a l'Aigle at 2.2 km, Lac Chasse out at 2.7 km and Lac a l'Aigle at 3.2 km. This one is safely inside the county line.
Depth is unmeasured here, so let the shoreline guide you. Still water like this holds fish on the edges rather than out in the open. Look for the band where the shallows give up and the bottom falls away. Public occurrence data for Côte-Nord names logperch. The county figures include rivers and lakes alike. The shape of Lac Therrien decides where the fish sit.
Long-term averages put July at about 16°C and January near -18°C. The fishing year opens late and shuts early. Count the season from break-up, usually early May. On the long-run averages the water opens up around early May and starts locking again about mid November. Spring is short and heavy here; autumn is longer and steadier. That shapes the year on Lac Therrien.
There is no clear statement anywhere on who can fish it. There is no mapped parking or launch close by, which usually means walking in. Perch take small lures and worms fished near the bottom close to structure. Where access is informal, keep it that way by behaving. Night access is frequently treated as a separate matter. The nearest alternative is Lac Piche, 1.8 km out. Check the position on Lac Therrien before loading the car.
