The Natevier River originates at the mouth of Cummings Lake in the township of Roy. This lake is located on the west side of Mount Cummings with a peak of. Around twenty cottages were built on the north shore of this lake and a small lake upstream. This source of the river is located at:
south-west of the mouth of the Natevier River ;
south-east of the bay Route of Waconichi Lake;
south-west of Mistassini Lake;
north-east of downtown Chibougamau.
From the mouth of Cummings Lake, the Natevier River flows over, according to the following segments:
north in the township of Roy along route 167 to the bridge of a road junction leading to Lake Bourbeau ;
northeasterly along the northwestern side of route 167, crossing a marsh zone and then crossing over a little unidentified lake, to its mouth;
northeasterly forming an eighth-eighth note to the east where it forms a loop east of route 167, then along this same road on the north-west side and collects the discharge of Lake Vignon, to the mouth of the river.
The Natevier River flows to the west bank of the Oreille River; the latter is a tributary of the North shore of the Blondeau River which flows to the north shore of McKenzie Bay of Chibougamau Lake. From this mouth, the current crosses this bay to the south, borrows the McKenzie Passage which is crossed by a road bridge, before crossing it to the Southwest on Chibougamau Lake bypassing the island of Portage which bounded on the northeast by Dorés Lake. Chibougamau Lake is the main head lake of Chibougamau River. From the mouth of Chibougamau Lake, the current flows through Dorés Lake, and then generally descends to the Southwest along 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. 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. The mouth of the "Natevier River" located at:
south-east of Waconichi Lake;
south-west of the bay south of Mistassini Lake;
northwest of the mouth of the Oreille River;
northwest of the mouth of the Blondeau River ;
North of the mouth of Chibougamau Lake;
north-east of the mouth of the Chibougamau River (confluence with the Opawica River;
