The hydrographic slope of the Porc-Épic River is served mainly by a secondary forest road that goes up this valley for forestry and recreational tourism purposes.[1]

Forestry is the main economic activity of the sector; recreational tourism activities, second.

The surface of the Porc-Épic River is usually frozen from early December to late March, however, safe ice movement is generally from mid-December to mid-March.

Geography

The mouth of the Porc-Épic River is located between the territories of the Grands-Jardins National Park and Hautes-Gorges-de-la-Rivière-Malbaie National Park; between Ha! Ha! Lake and the Lac des Martres.

The main hydrographic slopes near the Porc-Épic River are:

• north side: Malbaie River, Cran Rouge Creek, Moreau Lake, Des Martres River;
• east side: Beaulieu Lake, Lac des Martres, Barley Lake, Rivière du Gouffre;
• south side: Cold Creek, Hache Lake, Coq Lake, Barley River, Malbaie River;
• west side: Malbaie River, La Cruche Lake, La Cruche River, Ha! Ha! River.[1]

The Porc-Épic River originates at the mouth of Lac de la Hache (length: 0.7 km (0.43 mi); altitude: 712 m (2,336 ft)). The mouth of this lake is located at:

• 3.1 km (1.9 mi) west of a bay of Lac des Martres;
• 3.7 km (2.3 mi) east of a curve of the Malbaie River;
• 3.7 km (2.3 mi) northeast of the Barley [river];
• 7.8 km (4.8 mi) south-west of Beaulieu Lake;
• 7.8 km (4.8 mi) northwest of Little Malbaie Lake, head lake of the Little Malbaie River;
• 10.2 km (6.3 mi) south-west of a curve of the upper course of the Rivière du Gouffre;
• 6.6 km (4.1 mi) south-east of the confluence of the Porc-Épic River and the Malbaie River.[1]

From its source (Pimpant Lake), the Porc-Épic River descends on 9.2 km (5.7 mi) entirely in forested and mountainous zones, with a difference of 127 m (417 ft) according to the following segments:

• 1.5 km (0.93 mi) northerly crossing an unidentified lake (length: 0.6 km (0.37 mi); altitude: 933 km (580 mi)) surrounded by marshes, up to the discharge (coming from the east) of Beaulieu Lake;
• 2.7 km (1.7 mi) in a steep valley, first to the north, curving east, then north again, collecting a stream (from the northwest), a stream (coming from the northeast);
• 1.5 km (0.93 mi) to the northwest forming two small hooks, to the discharge (from the east) of the lake of the titmouse;
• 2.5 km (1.6 mi) northwesterly to the outlet (from the north) of an unidentified lake enclosed by mountains;
• 1.0 km (0.62 mi) westerly in a steep valley to its mouth.[1]

The Porc-Épic River flows into a swirl zone on the west bank of the Malbaie River. This confluence is located at:

• 0.7 km (0.43 mi) upstream of the mouth of the La Cruche River;
• 3.2 km (2.0 mi) northeast of the mouth of La Cruche Lake;
• 8.2 km (5.1 mi) east of the Ha! Ha! River;
• 7.9 km (4.9 mi) north-west of lac des Martres;
• 11.8 km (7.3 mi) southeast of Little Ha! Ha! Lake;
• 51.2 km (31.8 mi) west of the confluence of the Malbaie River and the St. Lawrence River.[2]

From the confluence of the Porc-Épic River, the current flows down the Malbaie River to 91.1 km (56.6 mi) east, then south-east, which flows over the northwest shore of the St. Lawrence River.
