The river descends 264 metres (866 ft) over its 46-kilometre (29 mi) course.[1]
In the area known as the Upper Henty at the river's headwaters is the Henty Gold Mine.[2][3] Its upper reaches were some of the last sites of dam making by the Hydro Tasmania in its long history of regulating flow of Tasmanian rivers.[citation needed]
The river catchment has two areas of high ground. One is known as the Professor Plateau, west of the Professor Range to the north of the river, and the other Misery Flat, which is high ground between the Tully River and Lost Creek.[4]
The river basin is adjacent to the West Coast Range and the Lake Margaret areas, argued as having up to four separate periods of glaciation.[5]
