Forestry is the main economic activity of the sector; recreational tourism activities, second. The valley of the Aigle River is served by the forest road R1053 which passes on the north-west side and north of Hébert Lake. This road joins the road R1009 which passes to the East of the river of Eagle. The surface of the Eagle River is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

The Eagle River originates at the mouth of an unidentified lake in the southern part of the township. Kalm, in Eeyou Istchee James Bay. The mouth of this small lake is located at:
From the mouth of the head lake, the Aigle River flows over according to the following segments: Upper course of the Eagle River
North in the Kalm township, to the western limit of the township of Coursol;
north along the western boundary of the township of Coursol;
northeasterly across wetlands and widening in places to the southwestern shore of Lacroix Lake;
to the northeast, crossing the Lac Lacroix. Note: Located in the Lacroix township, Lacroix Lake overlaps the administrative regions of Abitibi-Témiscamingue and Nord-du-Québec ;
Intermediate course of the Eagle River
north-east, to the limit of the canton of Espinay;
north-east in Espinay Township, to the outlet of L'Espinay Lake;
northeasterly to the outlet of "Rocky Island Lake";
northeasterly to the southern boundary of Machault Township;
North in the Township of Machault, bypassing two islands on the east side to the outlet of Lakes Suzie and Ann;
to the North, bypassing an island at the beginning of the segment, then forming a curve to the East, to the southern limit of the canton of Gradis;
North in Gradis Township, to the Horsefly Lake Landfill ;

to the northwest, to the outlet of two lakes;
northeasterly to its mouth.
The Aigle River flows on the south shore of a bay stretching over south of Doda Lake. The northern part of this lake is crossed to the West by the Opawica River. From there, the current of this river generally descends to the West, crossing in particular Doda Lake, Françoise Lake, La Ronde Lake, Lessard Lake, Lichen Lake, then north across Wachigabau Lake and Opawica Lake to its confluence with the Chibougamau River; this confluence is the source of the Waswanipi River. The course runs westward through the northern portion of lake Waswanipi, Goéland Lake and Lake Olga, before pouring into the Matagami Lake; the latter in turn flows into the Nottaway River, a tributary of Rupert Bay. The confluence of the Eagle River with the Opawica River is located at:
east of the mouth of Doda Lake;
east of the mouth of the Opawica River, being the head of the Waswanipi River;
At various times in history, this territory has been occupied by the Attikameks, the Algonquins and the Crees. This hydronym refers to a large diurnal rapacious bird with hooked bill and powerful greenhouses. The toponym "Eagle River" was formalized on December 5, 1968, at the Commission de toponymie du Québec.
