Baz Plenty of water in the Warrego at Cunnamulla,stayed there last friday 30th,also plenty of water in the Lachlan at Bourke but I dont know of any camps on the river at either places.As you probably know there is c/parks at both spots,Warrego Riverside (new park)at Cunnamulla and Kidmans Camp at Bourke.We did free camp at Enngonia Sth but was nowhere near the river (I think)Hope this helps a bit.
Cheers another Baz
