The Yule River is an ephemeral river in the Pilbara region of Western Australia.
The headwaters of the river rise in the Abydos Plain between the Chichester Range and the Mungaroona Range in the Scientific Reserve then flow in a north westerly direction crossing the North West Coastal Highway approximately 60 kilometres (37 mi) South of Port Hedland then discharging into the Indian Ocean near Cape Thouin. The river become more braided as it flows northward producing a wide alluvial riverbed, in the latter part of the journey the river bifurcates into the Yule and the Yule River West branch. The river forms a large estuary at the river mouth with an area of 31.4 square kilometres (12 sq mi)[3]
The river has ten tributaries, including Cockerega River, West Yule River, Pilbara Creek, Friendly Creek and Coorong Creek.
The river flows through a number of permanent pools, including Kangan Pool and Moolkamudda Pool.
During drought conditions the river has recorded zero flow for 2 years duration. The river also occasionally floods, particularly in 1975 when Cyclone Joan inundated the catchment area. The flood flow discharge was estimated at 22,000 m3 s-1 at the rivers peak.
The river's water quality varies depending on the flow, but the average turbidity of the river water is 187 NTU and the average salinity is 105 mg/L.
The traditional owners of the area are the Njamal or Nyamal peoples.[4]
The river was visited in 1861 by the explorer and surveyor Francis Gregory.[5]
