The upper part of the ruisseau L’Abbé valley is accessible by route 169; other secondary forest roads have been developed in the sector for forestry and recreational tourism activities [1] · [2] · [3].

Forestry is the primary economic activity in the sector; recreational tourism, second.

The surface of L’Abbé Creek is usually frozen from late November to early April, however safe circulation on the ice is generally from mid-December to late March.

From the small head lake, the course of the ruisseau L’Abbé flows over 19.3 km (12.0 mi) entirely in the forest zone, with a drop of 99 km (62 mi), according to the following segments:

Upper stream of ruisseau L’Abbé (segment of 9.2 km (5.7 mi))

  • 2.0 km (1.2 mi) north-east, up to a bend in the river;
  • 4.2 km (2.6 mi) towards the east by collecting the discharge (coming from the northeast) of the Florian lake and the discharge (coming from the southwest) of the lake of Écluse, until the discharge (from the northwest) of Brulé and Sarcelle lakes;
  • 1.5 km (0.93 mi) south-east in a deep valley, until the discharge (coming from the south) of a set of lakes including Lac à la Tranche, lac à Brod and lac Beaver;
  • 1.5 km (0.93 mi) east to Luppanay stream (coming from the south);

From the confluence of L'Abbé stream with the Pikauba River, the current successively descends the Pikauba River on 8.4 km (5.2 mi) to the northeast, then the current crosses Kenogami Lake on 17.6 km (10.9 mi) north-east to the dam of Portage-des-Roches, then follow the course of the Chicoutimi river on 26.2 km (16.3 mi) towards the east, then the northeast, and the course of the Saguenay River on 114.6 km (71.2 mi) towards the east until Tadoussac where it merges with the Saint Lawrence estuary[1].
