The Dumaresq River /djuːˈmɛrɪk/; (Indigenous Bigambul: Karaula)[1] a perennial stream of the Macintyre catchment within the Murray–Darling basin, is located in the Northern Tablelands and North West Slopes regions of New South Wales and the Darling Downs region of Queensland, Australia.

The Dumaresq River flows through Bonshaw, New South Wales and Yelarbon and Texas in Queensland.

Farmers in the valley once supported the tobacco industry with crop near towns such as Texas.

[citation needed] The river was visited by European explorer and botanist, Allan Cunningham, in 1827 and named in honour of Lt-Colonel Henry Dumaresq, a relative of Ralph Darling,[1][2] the Governor of New South Wales at that time.

The river has an important role in the sustainability of livelihoods of people who live on and near its banks.
