The Ventadour River originates at the mouth of a Georges Lake (length: 0.7 kilometres (0.43 mi), altitude: 433 metres (1,421 ft)) in the Ventadour Township. The mouth of this lake is located in the Haute-Mauricie Park at 0.8 kilometres (0.50 mi) west of the Eeyou Istchee James Bay (municipality) boundary and the regional county municipality (MRC) Le Domaine-du-Roy. Lake George and its neighbor to the west, Lion Lake, are the two most southerly lakes of Eeyou Istchee James Bay (municipality). Lake Georges is located at 3.3 kilometres (2.1 mi) south-west of Normandin Lake which is the head lake of the Normandin River, a tributary of the Ashuapmushuan River which in turn flows to the shore West of Lac Saint-Jean.

The mouth of Lake George is located at:

• 26.4 kilometres (16.4 mi) south of the mouth of the Ventadour River (confluence with Robert Lake (Opawica River tributary));
• 47.2 kilometres (29.3 mi) south-east of the mouth of Gabriel Lake (Opawica River tributary);
• 68.2 kilometres (42.4 mi) south-east of the mouth of Caopatina Lake;
• 145.6 kilometres (90.5 mi) south-east of the confluence of the Opawica River and Chibougamau River, the head of the Waswanipi River;
• 418 kilometres (260 mi) southeasterly of the mouth of the Nottaway River (confluence with James Bay);
• 113.1 kilometres (70.3 mi) south-east of downtown Chibougamau;
• 26.7 kilometres (16.6 mi) north-east of Gouin Reservoir.

From the mouth of the head lake, the Ventadour River flows over 33.5 kilometres (20.8 mi) according to the following segments:

• 2.2 kilometres (1.4 mi) North in the Township of Ventadour to the mouth of Quinn Lake (Length: 1.2 kilometres (0.75 mi); altitude: 427 metres (1,401 ft)) that the current flows through its full length;
• 0.9 kilometres (0.56 mi) westerly to the Geaty Lake discharge (from the south);
• 2.4 kilometres (1.5 mi) north, crossing Nairn Lake (length: 3.3 kilometres (2.1 mi); altitude: 418 metres (1,371 ft)), to the mouth of the last, where a road bridge is laid out;
• 1.3 kilometres (0.81 mi) north, to a second road bridge;
• 16.6 kilometres (10.3 mi) to the north, crossing Lake Ventadour (altitude: 424 metres (1,391 ft)) on its full length when entering the canton of Feuquières for the last 2.6 kilometres (1.6 mi) from the northern part of the lake;
• 10.1 kilometres (6.3 mi) north to mouth.[2]

The Ventadour River flows into a bay on the south shore of Boucher Lake (Opawica River). From there, the current flows through this lake, which flows to the east shore of Gabriel Lake (Opawica River tributary). The latter, in turn, generally goes northwest, then west, then north, to its confluence with the Chibougamau River; this confluence is the source of the Waswanipi River. The course of the latter flows westward and crosses successively the northern part of Lake Waswanipi, the Goéland Lake and the Olga Lake (Waswanipi River), before discharging into Matagami Lake which in turn flows into the Nottaway River, a tributary of Rupert Bay (James Bay).

The confluence of the Ventadour River with Robert Lake is located at:

• 10.2 kilometres (6.3 mi) south of the mouth of Robert Lake;
• 21.1 kilometres (13.1 mi) south-east of the mouth of Gabriel Lake (Opawica River tributary);
• 17.1 kilometres (10.6 mi) south of a bay Rohault Lake;
• 135.6 kilometres (84.3 mi) south-east of the mouth of the Opawica River (confluence with the Chibougamau River);
• 85.1 kilometres (52.9 mi) South of downtown Chibougamau;
• 81.2 kilometres (50.5 mi) south-east of the village center of Chapais, Quebec;
• 41.1 kilometres (25.5 mi) north of a bay on the north shore of Gouin Reservoir.
