From the foothills of the Herveys Range, the Bogan River rises to the west of the headwaters of the Little River at Cooks Myalls, near Goonumbla, 19 kilometres (12 mi) north-west of Parkes. The river flows in a generally north-north-westerly direction past Tottenham, Peak Hill and through Nyngan. East of Bourke, the Bogan River joins with the Little Bogan River to form the Darling River. The Bogan River has over twenty tributaries. The main tributaries to the west are Bullock, Bulbodney, Pangee and Whitbarrow Creeks. The eastern catchment between the Bogan and Macquarie Rivers is ill-defined and has only one major tributary, Mulla Cowal.:11 Other sources have claimed that Bugwah Cowal, and Burrill, Duck and Gunningbar Creeks are important tributaries.
Major weirs along the watercourse are at Muddal Weir, located west of Peak Hill; the Nyngan Weir, located north of Nyngan; and Gongolgon Weir, where the mean daily flow exceeds 700 megalitres (25×106 cu ft).:16
A number of Aboriginal peoples lived in the lands surrounding the Bogan River for many thousands of years. In the area surrounding Peak Hill, the indigenous inhabitants of the area were the Wiradjuri clan. In the area surrounding Nyngan, the Ngiyambaa Aboriginal people were the principal custodians of the land.
The river was crossed by John Oxley in 1817, but was named by Charles Sturt in his 1828-9 expedition as New Years Creek on 1 January 1829. It was also called the Bogan River prior to Major Sir Thomas Mitchell reaching here in 1835. On 17 April 1835 Richard Cunningham wandered away from the Mitchell party near the Bogan River and it is believed that he was killed here by Aborigines.
In April 1990, major flooding occurred along the river and in Nyngan, and despite a massive effort by local people to build levee walls using sandbags, 2,500 people had to be evacuated from the town. The floods caused A$50 million damage with the railway line so severely affected that rail services to Nyngan have since ceased, although freight services from Cobar are unaffected. Other significant flooding of the Bogan River occurred in 1928.
