The Darling is a tributary of the Murray, but the Darling is 1,701 miles long and the Murray 1,600 miles (including the stretch below the confluence). The stretch below the confluence measures about 400 miles, making the maximum length of the Murray/Darling river system about 2,100 miles – the 18th longest in the world; the Darling on its own would be 29th, after the Danube (1,770 miles).
