The surrounding hydrographic slopes of the “Queue de Castor River” are:

• north side: Cawcot River, Robert Lake (Opawica River tributary), Gabriel Lake (Opawica River tributary), Rohault Lake, Opawica River;
• east side: Ventadour River, Titipiti River, Robert Lake (Opawica River tributary), Normandin River, Poutrincourt Lake, Ashuapmushuan River;

The “Queue de Castor River” originates at the mouth of a Beaucours lake (length: 8.4 kilometres (5.2 mi); altitude: 405 metres (1,329 ft)) in Beaucours Township, in the Eeyou Istchee James Bay (municipality). This V-shaped lake has several small bodies of water in the northwest. It is fed by the Beaucours Creek (coming from the South).

The mouth of Beaucours Lake is located at 14.3 kilometres (8.9 mi) west of the Eeyou Istchee James Bay (municipality) boundary and the Regional County Municipality (RCM) Le Domaine-du-Roy.

The mouth of lake Beaucours is located at:

• 17.5 kilometres (10.9 mi) South of the mouth of the “Queue de Castor River” (confluence with Gabriel Lake);
• 29.4 kilometres (18.3 mi) south-east of the mouth of Gabriel Lake (Opawica River tributary);
• 47.9 kilometres (29.8 mi) south-east of the mouth of Caopatina Lake;
• 125.8 kilometres (78.2 mi) southeast of the confluence of the Opawica River and Chibougamau River, the head of the Waswanipi River;
• 388.4 kilometres (241.3 mi) southeasterly of the mouth of the Nottaway River (confluence with James Bay);
• 94.0 kilometres (58.4 mi) south-east of downtown Chibougamau;
• 28.6 kilometres (17.8 mi) north-east of Gouin Reservoir.

From the mouth of the head lake, the "Queue de Castor River" flows on 23.6 kilometres (14.7 mi) according to the following segments:

• 1.5 kilometres (0.93 mi) southeasterly to the west bank of an unidentified lake;
• 3.9 kilometres (2.4 mi) northeasterly across the northern part of an unidentified lake (length: 9.3 kilometres (5.8 mi); altitude: 402 metres (1,319 ft) ) to a road bridge;
• 6.4 kilometres (4.0 mi) to the north, crossing an unidentified lake (length: 4.0 kilometres (2.5 mi); altitude: 401 metres (1,316 ft)) that the current crosses on its full length, as far as the bridge of a forest road;
• 7.0 kilometres (4.3 mi) northeasterly across an area where the river widens to the limit of Robert Township;
• 4.8 kilometres (3.0 mi) northwesterly in Robert Township winding to mouth.^[2]

The “Queue de Castor River” flows into the bottom of a bay on the south shore of Gabriel Lake (Opawica River tributary) which flows through the North on 13.4 kilometres (8.3 mi). 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 flows westward through the northern portion of Lake Waswanipi, Goéland Lake and Olga Lake, before pouring into the Matagami Lake which in turn flows into the Nottaway River, a tributary of Rupert Bay (James Bay).

The confluence of the "Queue de Castor River" with the Feuquières Lake is located at:

• 13.0 kilometres (8.1 mi) south-east of the mouth of Gabriel Lake (Opawica River tributary);
• 121.9 kilometres (75.7 mi) south-east of the mouth of the Opawica River (confluence with the Chibougamau River);
• 76.1 kilometres (47.3 mi) south of downtown Chibougamau;
• 68.5 kilometres (42.6 mi) south-east of the village center of Chapais, Quebec;
• 46.2 kilometres (28.7 mi) north of a bay on the north shore of Gouin Reservoir.
