Cordeaux River


The Cordeaux River, a perennial river of the Hawkesbury-Nepean catchment, is located in the Southern Highlands and Macarthur regions of New South Wales, Australia.

Course

The river is impounded by Lake Cordeaux, one of four reservoirs within the Upper Nepean Scheme that supplies potable water for greater metropolitan Sydney. Located near Ryans Crossing, approximately south-west of Sydney, construction of the dam wall on the Cordeaux River commenced in 1918 and was completed in 1926.
