Lac d'Ostis in Saguenay/Lac-Saint-Jean: How and When to Fish It

• Overview

  Lac d'Ostis stands in Saguenay/Lac-Saint-Jean, Quebec. It lies 533 metres above sea level. Small at around 8 hectares: two anglers spread out cover most of it. The bank runs about 2.1 km all the way round, so one visit can cover most of it. Compared with other Quebec water on our list, it sits high. Saint-Félicien sits 32 km from here and is the nearest stop. It is 133 km to Saguenay, the nearest city. Rules here are straightforward: one set of provincial rules.

• Where to Fish on Lac d'Ostis

  The records we hold are silent on depth, so plan to find it yourself. The shallow end warms first and pulls fish in ahead of the rest. Weed, then depth: that is the order to fish a water of this kind. County-wide records name northern pike, Atlantic salmon, lake whitefish and fallfish. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. At Lac d'Ostis the water rewards a slow, careful approach.

• Seasonal Patterns

  Climate normals give 16°C for July and -18°C for January. The season is measured in weeks rather than months. Once it clears, about early May, the fishing comes on quickly. The lid tends to go about early May and return around mid November. Fish feed hardest at the start and the close of the open season. On Lac d'Ostis that shapes the whole year.

• Tackle & Baits

  There is no clear statement anywhere on who can fish it. Records list it as a natural water body rather than an impoundment. There is no mapped parking or launch nearby, which keeps numbers down. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. Parking is often the real limit rather than the bank itself. Where parking is tight, arriving early solves most problems. Failing this one, try Lac Vienne, 2.5 km away. Nothing here settles the position at Lac d'Ostis for certain.
