Sunrise at Balonne River

Lachlan River

ETA Unknown

The Lachlan River is considered to be the fourth longest river in Australia. Its source is on the Breadalbane Plain near Goulburn, on the Great Dividing Range. From here it flows westwards out onto the fertile plains of the Riverina and onto the semi-arid woodlands. The river ends at the Great Cumbung Swamp. Water will only reach the Murrumbidgee River during large floods.

I used the phrase "considered to be the fourth longest river" based on the approximations provided by GeoAustralia, but from my own analysis it closely ties with the third placed Darling River. Tracing satellite images in QGIS, I calculated that the Lachlan River at 1,547 km if it flows all the way to the Murrumbidgee River, and equals the length calculated for the Darling River. The main discrepancy between the measurements is that the Lachlan River snakes it way down at a much finer level than the Darling River, adding 15% to the estimated length. This distance discrepancy is greatest towards the source.
