If you stand beside Seven Creeks in Victoria or Spring Creek in Queensland, they might seem small and unremarkable. But these creeks flow into the mighty Goulburn and Condamine Rivers, and punch far above their weight.
Small headwater creeks, at the beginning of a river network, act as the first source of water for bigger rivers. Headwaters deliver the first cool winter flows and the large seasonal pulses of water that trigger fish migration, setting the river’s rhythm. But they’re also the first to suffer from drought, heatwaves and water captured by thousands of small farm dams.
