The "Nepton North River" originates at the mouth of an unidentified lake (length: 0.8 kilometres (0.50 mi) altitude: 499 metres (1,637 ft)) in the township from McCorkill. This lake is located northwest of a mountain with a peak of 595 metres (1,952 ft); this summit corresponds to the limit of the MRC Eeyou Istchee Baie-James (administrative region of Nord-du-Québec) and (Saguenay-Lac-Saint-Jean) This source is located at:

• 5.4 kilometres (3.4 mi) north-east of the mouth of the Nepton River (confluence with Nepton River (Chibougamau Lake));
• 17.8 kilometres (11.1 mi) south-east of Waconichi Lake;
• 27.7 kilometres (17.2 mi) south of Mistassini Lake;
• 13.5 kilometres (8.4 mi) north-east of the mouth of the Nepton River (Chibougamau Lake);
• North of downtown Chibougamau.

From its source, the Nepton North River flows over 6.4 kilometres (4.0 mi) generally to the southwest.^[2]

The Nepton North River flows into a river bend on the north shore of the Nepton River (Chibougamau Lake). The latter flows generally northwesterly to the bottom of a narrow bay on the northeastern shore of Nepton Bay which is an extension of the Bay of Islands, northeast of Chibougamau Lake and is connected to Girard Bay. From the mouth of the Nepton River, a peninsula is advancing in a straight line on the south-west in the bay to the outlet of Forest Lake. The mouth of the Nepton River is located at 0.4 kilometres (0.25 mi) east of the boundaries of Roy and McCorkill Townships.

From this mouth, the current flows over 18.3 kilometres (11.4 mi) first crossing this bay towards the West which includes many islands, in crossing west to Chibougamau Lake and bypassing Portage Island. The Chibougamau Lake is the main head lake of Chibougamau River.

From the mouth of Chibougamau Lake, the current crosses the , then descends generally to the southwest (except the large S of the upper part of the river) by taking the Chibougamau River, to its confluence with the Opawica River. From this confluence, the current flows generally southwesterly through the Waswanipi River to the east shore of Goéland Lake (Waswanipi River). The latter is crossed to the northwest by the Waswanipi River which is a tributary of Matagami Lake. Finally, the current flows along the Nottaway River and empties into Rupert Bay, south of James Bay.

• 24.4 kilometres (15.2 mi) South-east of Waconichi Lake;
• 42.4 kilometres (26.3 mi) South of Mistassini Lake;
• 8.4 kilometres (5.2 mi) North-east of the mouth of the Nepton River (Chibougamau Lake);
• 22.6 kilometres (14.0 mi) North of the mouth of Chibougamau Lake;
• 161.3 kilometres (100.2 mi) North-east of the mouth of the Chibougamau River (confluence with the Opawica River);
