The bras Sec (English: Dry Arm) 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.[1]
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.
The main watersheds neighboring the Sec arm are:
Le Bras Sec rises at the mouth of Lake Catellier (length: 0.5km (00.3miles); altitude: 671m (2,201feet)) 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:
From Lac Catellier, the Bras Sec flows over 26.2km (16.3miles) with a drop of 341m (1,119feet) entirely in the forest zone, according to the following segments:
Upper course of the Bras Sec (segment of 18.1km (11.2miles))
Lower course of the Bras Se (segment of 8.1km (05miles))
The Sec arm flows into a bend in the west bank of the rivière du Moulin, near (west side) of Coupau lake. This confluence is located at:
From the mouth of the Sec arm, the current successively follows the course of the rivière du Moulin on 52.7km (32.7miles) generally north, then the course from the Saguenay River on 126.1km (78.4miles) eastwards to Tadoussac where it merges with the Saint Lawrence Estuary.[2]
The term "Sec" (English: Dry) refers to the fact that in certain periods of drought, this stream is almost dry.
The toponym "bras Sec" was formalized on June 29, 1983, at the Place Names Bank of the Commission de toponymie du Québec.[3]
