Intertidal

​As the river passes the town of Latrobe the sea begins to influence its structure, a delta and estuary have formed as the water loses speed, salt helps deposit sediment forming the wide mudflats visible at low tides. A lot of human effort was, and continues to be employed to open the river to the sea for shipping. The remains of dredging ship are still visible near the river mouth, covered shellfish, and rust.

The river port allows people and produce to move in and out of Tasmanian, it is part of the national highway system. The spectacle of the big red ferry rotating in the river is enthralling to visitors and residents alike.

As the river flows through this section and out into Bass Strait it is barely recognisable as the same wild river flowing over waterfalls and through cliff lined gorges. It is wide and slow, often murky and obscured by ships and trains. Finally upon reaching the mouth, the river can hardly be distinguished from the sea, waves roll up the river and sediment flows out, it is only during a flood event that we are reminded the river is strong and beyond our control.
