The valley of the rivière aux Écorces Nord-Est is served indirectly by the route 169 and directly by the forest road R0261 which goes up the valley of the rivière aux Écorces and the Rivière aux Écorces Nord-East. This valley is also served by some 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 rivière aux Écorces North-East is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.

Upper course of the Rivière aux Écorces Nort-East (segment of 23.5 kilometres (14.6 mi))
- 1.7 kilometres (1.1 mi) towards the northwest in particular by crossing Lake Vézina (length: 1.1 kilometres (0.68 mi); altitude: 821 metres (2,694 ft)) on 1.0 kilometre (0.62 mi), to its mouth;
- 9.9 kilometres (6.2 mi) towards the northeast by meandering, until the outlet (coming from the southeast) of Jacqueline Lake;
- 1.5 kilometres (0.93 mi) to the west, forming a curve towards the north, up to the outlet (coming from the south) of Lac aux Loups;
- 4.4 kilometres (2.7 mi) north-west across rapids, to Madeleine stream (coming from the north-east);
- 1.3 kilometres (0.81 mi) towards the south-west crossing three series of rapids and curving towards the north-west, up to Delphis stream (coming from the south);
- 4.7 kilometres (2.9 mi) towards the northwest by forming a loop towards the east in the middle of the segment and another towards the south at the end of the segment, up to the Portage stream (coming from the north);
Intermediate course of the Rivière aux Écorces North-East (segment of 17.7 kilometres (11.0 mi))
- 2.2 kilometres (1.4 mi) south passing between two mountains, to Joyal stream (coming from the south);
- 2.1 kilometres (1.3 mi) north-west curving west, to a bend in the river;
- 2.9 kilometres (1.8 mi) towards the southwest, curving towards the west, collecting the outlet (coming from the southwest) from lac Gineau and the Martel stream (coming from the south) to the outlet (coming from the north) from Lac Duchâtelets;

Lower reaches of the North East Bark River (segment of 13.1 kilometres (8.1 mi))
