The river's path is shaped by a complex network of tributaries—smaller streams and rivers that flow into a larger main river. These tributaries feed the Stour from both sides, ensuring a consistent flow as it moves toward the coast.
Left Bank Tributaries
Feeding into the left side of the river are the River Allen, the Moors River, the River Tarrant, and the River Lodden.
Right Bank Tributaries
The right side of the river is joined by the River Divelish, the River Lydden, and the River Cale.
Regional Impact and Infrastructure
The River Stour flows through multiple districts, including Salisbury, Somerset, Dorset, and the Bournemouth, Christchurch, and Poole area. Along its course, the river interacts with various man-made structures, including numerous mills such as Bourton Mill, Highbridge Mill, and Throop Mill, as well as several major road crossings like the A303, A357, and A31.
As the river approaches its end, it enters a tidal reach where the influence of the sea becomes apparent. The journey concludes at Christchurch Harbour in Dorset, where the river finally drains into the English Channel.
