The Again River originates at the mouth of Lake Mine (length: 3.4 kilometres (2.1 mi), elevation: 267 metres (876 ft)) in the eastern part of the Cochrane District.

The source of the Again River is located at:

  • 10.4 kilometres (6.5 mi) at the east of the Ontario border;
  • 92.5 kilometres (57.5 mi) at the south of the mouth of the Again River;
  • 37.6 kilometres (23.4 mi) east of Kesagami Lake (Ontario);
  • 118.5 kilometres (73.6 mi) at the south of the mouth of the Harricana River, in Ontario.

From its source, the Again River runs more or less parallel to the Ontario border on 119.9 kilometres (74.5 mi) in the following segments:

  • 16.0 kilometres (9.9 mi) to the north through three lakes, northeasterly through two lakes including Lake Favell (Ontario) and eastward up to a branch line (from the south- East) which drains the cross-border area between Quebec andOntario;
  • 55.0 kilometres (34.2 mi) to the boundary between Quebec and Ontario;
  • 46.3 kilometres (28.8 mi) to the north in Quebec more or less along the interprovincial boundary and in a marsh area, until the cut between the boundary between Quebec and Ontario;
  • 2.6 kilometres (1.6 mi) to the north-west in the Cochrane District in Ontario in the marsh area to the mouth.[2]

The Again River flows into the southwestern shore of the Harricana River in front of Low Shoal Island. This confluence is located at:

  • 31.0 kilometres (19.3 mi) at southeast of the mouth of the Harricana River;
  • 2.6 kilometres (1.6 mi) at west of the boundary between Quebec and Ontario;
  • 88.6 kilometres (55.1 mi) at south of the center of the village of Moosonee inOntario.
