Edward River, or Kolety is an anabranch of the Murray River and part of the Murray–Darling basin, is located in the western Riverina region of south-western New South Wales, Australia. The river rises at Picnic Point east of Mathoura, as a result of the bottleneck created in the Murray by the Cadell Fault, and flows generally north through river red gum forest, reaching Deniliquin and then flowing generally west through Moulamein. It is joined by six minor tributaries, before reaching its confluence with the Wakool River and re-entering the Murray at Wakool Junction, near Kyalite. The river descends 49 m over its 383 km course. Kolety was gazetted as a dual official name for the river in 2006.
