Chasing the Flood
Analysis of flood waters on the Darling River
The online map has markers every km starting from 0 at the confluence where the Darling meets the Murray. At the Culgoa and Barwon confluence these separate out marking both the Culgoa to Condmine and Barwon to Macintyre systems to their respective sources.
Zoom in to see all of these markers. These do not correlate with any existing numbering system on the river.
The mapping of the NSW Water Authority blue signs and the numbering system is closely aligned but differs slightly:
It was difficult to accurately navigate using the maps for Condamine, Balonne and Culgoa rivers due to the frequent twists and turns and complete lack of things to take a bearing on. A GPS device is strongly recommended as an additional navigation aid if you want to accurately track your progress.
In high flows, the river covers the floodplains. Navigation is mainly based on tracking the river gums. I found it best to check my GPS when the river split and the main channel was difficult to distinguish.
