The River Blackwater is a tributary of the Loddon in England and sub-tributary of the Thames. It rises at two springs in Rowhill Nature Reserve between Aldershot, Hampshire and Farnham, Surrey. It curves a course north then west to join the Loddon in Swallowfield civil parish, central Berkshire. Part of the river splits Hampshire from Surrey; a smaller part does so as to Hampshire and Berkshire.
The source is locally rare heath within the Thames Basin Heaths Special Protection Area, due to the Farnborough/Aldershot Built-up Area.
After 20 miles (32 km) the Blackwater is joined by the Whitewater near Eversley. The river gives its name to the town of Blackwater, extending back from the bank facing Camberley, and the wider urban area including Aldershot, Farnborough, and Camberley is sometimes collectively referred to as the Blackwater Valley.[1][2]
