The bras Sec is a tributary of the rivière du Moulin, flowing in the unorganized territory of Lac-Ministuk, in the Le Fjord-du-Saguenay Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada. The course of the Sec arm crosses the northwest part of the zec Mars-Moulin. The small valley of the Bras Sec is served by a few secondary forest roads, especially for forestry and recreational tourism activities. Forestry is the main economic activity in this valley; recreational tourism, second. The surface of the Dry arm is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally done from mid-December to mid-March.
Geography
The main watersheds neighboring the Sec arm are:
north side: Lac Vénus, Grand Lac, Lac des Éclats, rivière du Moulin;
west side: Cyriac River, Normand River, Savane stream.
Le Bras Sec rises at the mouth of Lake Catellier in a forest area in the zec Mars-Moulin. This landlocked lake between the mountains is located at the southwestern limit of the zec Mars-Moulin, that is to say:
south-west of the confluence of Bras Sec and rivière du Moulin;
north-east of the course of the Pikauba River.
From Lac Catellier, the Bras Sec flows over with a drop of entirely in the forest zone, according to the following segments: Upper course of the Bras Sec

making a difference in height from first to a bend in the river, then bending towards the northeast, to a stream ;
north-west passing west of a mountain and past a forest camp, to a stream ;
towards the north by making a detour towards the west to go around a mountain whose summit reaches, up to a bend of the river, corresponding to a stream ;
From the mouth of the Sec arm, the current successively follows the course of the rivière du Moulin on generally north, then the course from the Saguenay River on eastwards to Tadoussac where it merges with the Saint Lawrence Estuary.
