The river rises below Granite Mountain, east of Tumbarumba, on the western slopes of the Snowy Mountains within Bago State Forest, and its natural flow drains generally south, and then south-west, before reaching its confluence with the Tumbarumba Creek, north of the village of Tooma; descending over its course. The river is impounded by Paddys River Dam. Approximately south of Tumbarumba, the river descends over the Paddys River Falls.
