The river flows generally eastward, then circles around the southern end of the San Bernardo Mountains and then flows north-northeastward in several ramifications that end at the Musters Lake. On years of great precipitation, some arms of the river might reach the Colhué Huapi Lake, which has been greatly reduced in size in recent years. The average inflow is 49 cubic metres per second (1,700 cu ft/s).^[1]
