Distance markers

The online map has markers every km that represent a continuation of the numbering that starts at 0 where the Darling meets the Murray. Kilometre marker 1547 is slightly upstream of the Culgoa and Barwon confluence.

Zoom in to see all of these markers. These do not correlate with any existing numbering system on the river.
