• 35.5 kilometres (22.1 mi) southeast of the mouth of the Wetetnagami River;

From its source, the Panache River flows over 61.6 kilometres (38.3 mi) according to the following segments:

• 9.9 kilometres (6.2 mi) southwesterly in Urban Township, passing near the head of the Macho River (which flows south), to the eastern limit of Township of Carpiquet;
• 11.2 kilometres (7.0 mi) westerly in Urban Township, forming a southerly curve to Corriveau Brook (coming from the South);
• 3.7 kilometres (2.3 mi) north, then north-east, to the confluence of the Fortier River (coming from the East);
• 18.6 kilometres (11.6 mi) northwesterly forming a large northeasterly curve and winding to the confluence of the Pierrefonds River (coming from the northeast);
• 2.6 kilometres (1.6 mi) southwesterly to the eastern limit of the Township of Effiat;
• 15.6 kilometres (9.7 mi) in Effiat Township, first to the northwest, forming a curve to the southwest, touching the boundary of Canton de Muy, then easterly along on the south side the boundary of the townships of Muy and Effiat to its mouth.[2]

The Panache River flows to the northeastern shore of the Wetetnagami River flowing north and discharging into Nicobi Lake. The latter is the head lake of the Nicobi River. The latter flows north to discharge on the southeast bank of the Opawica River. The latter goes back to the north until it meets 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 (Waswanipi River), 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 Panache River with the Wetetnagami Lake is located at:

• 15.8 kilometres (9.8 mi) south of the mouth of the Wetetnagami River;
• 36.5 kilometres (22.7 mi) South of the mouth of the Nicobi River;
• 61.1 kilometres (38.0 mi) south of the mouth of the Opawica River (confluence with the Chibougamau River);
