- east side: Moose River, Longue Pointe watercourse, lake Aylmer, Saint-François River;
- south side: lake Aylmer, bay Ward;

The Coulombe River has its source in a marsh area 2.0 kilometres (1.2 mi) west of Mont Louise, 1.6 kilometres (0.99 mi) south of the village center Saints-Martyrs-Canadiens, 1.2 kilometres (0.75 mi) east of an abandoned quarry and 1.6 kilometres (0.99 mi) south of Sunday Lake.
From this marsh area, the course of the Coulombe River flows over 13.8 kilometres (8.6 mi) divided into the following segments:
- 3.1 kilometres (1.9 mi) eastward, up to the confluence of the outlet of Lac Rond;
- 2.6 kilometres (1.6 mi) eastward, to the north shore of Lac Coulombe;
- 0.8 kilometres (0.50 mi) crossing to the south-east the Coulombe lake (length: 1.4 kilometres (0.87 mi); altitude: 301 metres (988 ft)), i.e. the main plane of water drained by the Coulombe River;
- 0.8 kilometres (0.50 mi) east, up to route 161 which the river crosses at 4.2 kilometres (2.6 mi) west of the intersection of route 112;
- 2.8 kilometres (1.7 mi) eastward, to the confluence of the Coulombe North River which is the main tributary;
- 2.2 kilometres (1.4 mi) south-east to a country road;
- 1.5 kilometres (0.93 mi) towards the south-east, to its mouth.[1]
The Coulombe River empties on the west shore of Ward Bay of lake Aylmer. The mouth is located 1.3 kilometres (0.81 mi) (in a direct line) southwest of the intersection of route 161 and route 112 from the village of Beaulac-Garthby.
