Lachlan River
14 Jan to 03 Feb 2022
As far as I know, I'm the only person that has made it through the marshes since Kirdwood was guided by local aboriginal tribes back in 1878.
Many have pulled out at midway, usually at or before Booligal, with only a couple of people making it to Oxley. You have been warned!
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 Cumbungi 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 takes third place from the Darling River. Tracing satellite images in QGIS, I calculated that
the Lachlan River at 1,549 km if it flows all the way to the Murrumbidgee River, and is 2 km longer than
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.
The Murrumbidgee River seems to be considerably longer than both of these rivers.
