The Aigle River (French: Rivière de l'Aigle, meaning "Eagle River") is a tributary of the Désert River, passing through the municipalities of Cayamant and Montcerf-Lytton, in La Vallée-de-la-Gatineau Regional County Municipality, in the Outaouais administrative region, Quebec, Canada.
The surface of the river is generally frozen from mid-November to mid-April (except in fast-flowing areas).
The Mer Bleue Lake (length 5.5 km, altitude: 208 m), located in the municipality of Cayamant, Quebec, is the main body of water of the head of the Aigle River. Lake is located 27 km southwest of downtown Maniwaki, 22 km west of the Gatineau River, 9.0 km north of the hamlet "Lac-Cayamant" and 10.7 km west of "Blue Sea Lake" which is flanked on the east side by the Canadian National Railway section.
The Mer Bleue Lake has several bays, spiers / peninsulas advancing into the lake and many islands including "The Grosse Île" and the "Twin Islands". This lake receives the waters of:
The mouth of "Mer Bleue Lake" is located southeast of the lake. From there, the current runs eastward through a short strait of about 120 m, which separates the latter lake and the "Lac Lacroix" (which is shaped elbow, 2.8 km long). The hamlet "Le Grand-Aigle" is located in the bay south of the lake; the hamlet "Le Petit-Aigle" is located on the eastern shore of the lake, just south of "Petit lac de l'Aigle". Several other cottages are located in the area of the mouth of "Mer Bleue Lake".
From the outlet of the Strait, the current crosses Lac Lacon, 0.7 km east, bypassing a peninsula emerging from the south shore, to the entrance of the strait connecting the "Lac de l 'Eagle' (2,2 km long, altitude: 208 m). A road bridge spans the southern tip of this lake.
