Geography

River

The river rises on the slopes of Wilgoona Hill in the Robinson Ranges west of the Gibson Desert and flows near Carnarvon in the Shark Bay and thus in the Indian Ocean.

The Gascoyne River is composed of two arms:

  • The Gascoyne River North Branch is the northern, 125 km long arm and rises near the Collier Range
  • The Gascoyne River Middle Branch is the southern, 15 km long arm and springs near the settlement Doolgunna.

The Gascoyne River is also called " reverse flow " because he leads visible water only about 120 days a year and the rest of the year flows underground. This is due to a huge, natural water retention system, the aquifer lying under the desert sand.

The river flows through a sparsely vegetated landscape that is mainly used for gold mining and sheep farming. It flows through many pools that serve both the wild and farm animals as an important source of water.
