Chinchilla Weir Weirs & Barrages

Chinchilla Weir Weirs & Barrages


Chinchilla Weir

Chinchilla Weir, 8 km south of Chinchilla on the Condamine River, was built in 1973 to address a shortage of urban water supply for the town of Chinchilla.

It supplies irrigators upstream through the pond created by the weir and downstream from water releases.

Water helps the region’s agriculture industry, including beef and pork production, fruit and vegetable crops, cotton and most notably melons. Producing 25% of the country’s watermelons, rockmelons and honeydew melons, Chinchilla is the melon capital of Australia.
