The Ross River is a river located in northern Queensland, Australia. The river flows from Lake Ross, through the city of Townsville, across the flat coastal plain and into the Coral Sea of the Pacific Ocean. It is the major waterway flowing through Townsville and the city's main source of drinking water.
The river flows from the Hervey Range, northward and bends east around Mount Stuart into the city. The Ross River flows across the Townsville suburbs of Aitkenvale, Annandale, Condon, Kelso, Mundingburra, Murray and Rasmussen. The mouth of the river is located just south east of Townsville and is currently being developed into a marina precinct. Flow rates in the river are controlled by the Ross River Dam, the largest dam in the catchment. There are seven crossings over the river and three weirs exist along the river.
