Castlereagh River

Castlereagh River, from the Castlereagh Highway, south of Walgett, New South Wales

The Castlereagh River is located in the State of New South Wales, Australia. The river starts in the area north of Dubbo and goes through the towns of Gilgandra, Mendooran, Binnaway, Coonamble and Coonabarabran amongst others before flowing into the Darling River.

The Darling River is the longest river in Australia and itself flows into the Murray River forming a part of the largest river system in the continent. The catchment of the Murray-Darling Basin including the tributary of the Castlereagh River drains about twenty percent of the continental surface area of Australia.

The Castlereagh River was explored by John Oxley in 1818.^[1]
