The Minilya River is a river in the Gascoyne region of Western Australia.
The headwaters of the river rise in the south-west of the Black Range and flows in a generally westerly direction, joined by three minor tributaries: Minilya River South, Bee Well Creek and Naughton Creek. The river is crossed by the North West Coastal Highway near the Minilya Roadhouse and then later discharges into Lake MacLeod. The area is semi-arid with a landscape of woodland and scrub used for sheep and cattle grazing. The Minilya River descends over its 269km (167miles) course.[1]
The name of the river is Aboriginal in origin but its meaning is unknown. The first Europeans to visit the river were the explorers who named it, Charles Brockman and George Hamersley, who visited the area in 1876. Brockman and Hamersley also named the Lyndon River and Brockman later took up a 40000acres lease known as Boolathana then another property, Minilya Station.[4]
The traditional owners of the area are the Tharrkari and Baiyungu peoples.[5]
The soils throughout the river basin are eroded and the regional ecology is degraded as a result of cattle grazing from the numerous pastoral stations found through the area. As a result, fencing has been installed through the length of the river, water tanks and troughs installed and establishment of new grazing yards.[6]
The Minilya is prone to occasional flooding following heavy rain events as it did in 1905.[7] More flooding occurred 1918 when Minilya Station recorded 7.58inches in just over two months isolating the homestead.[8] Further flooding occurred in 1942 with many station homesteads being left isolated.[9]
