River course
The river rises on the slopes of Wilgoona Hill in the Robinson Ranges west of the Gibson Desert and flows into Shark Bay and thus into the Indian Ocean at Carnarvon .
The Gascoyne River is composed of two arms:
- The Gascoyne River North Branch is the northern 125 km long arm and has its source near the Collier Range
- The Gascoyne River Middle Branch is the southern, 15 km long arm and has its source at the settlement Doolgunna .
The Gascoyne River is also known as the “reverse flow” because it only has visible water for about 120 days a year and flows underground for the rest of the year. This is due to a huge, natural water retention system, the aquifers of which lie under the desert sand.
The river flows through a thinly vegetated landscape, which is mainly used for gold mining and sheep farming. It flows through many pools, which serve as an important source of water for both wild and farm animals.
Tributaries with mouth heights
The most important tributary is the 561 km long Lyons River , which meets the Gascoyne River at Gascoyne Junction about 160 km above the confluence with Shark Bay. Together, these two rivers have a catchment area of 68,326 km², which lies completely east of the Kennedy Ranges and extends about 480 km inland.
