Distance markers

The online map has markers every kilometer that start at 0 where the Macquarie meets the Barwon River up to 882 just before the source of the river at the Fish and Campbells River confluence. When entering the Barwon River, you are about 1,798.1 km from the ocean if you keep paddling down the Darling and Murray rivers.

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