The Rodger River rises below Monkeytop in a remote alpine wilderness area within the Snowy River National Park, and flows generally south, then west, then south, then south by west, joined by the Yalmy River and three minor tributaries, before reaching its confluence with the Snowy River downstream of Jackson Crossing in the Shire of East Gippsland. The river descends 744 metres (2,441 ft) over its 60-kilometre (37 mi) course.[2]
The entire course of the river is contained within Snowy River National Park.[2]
