River Blackwater (River Loddon)

River Blackwater (River Loddon)

The River Blackwater is a tributary of the River Loddon in England and, indirectly, of the River Thames. It rises at Rowhill on the outskirts of Aldershot between Aldershot in Hampshire and Farnham in Surrey and runs northwards to join the Loddon near the village of Swallowfield in Berkshire. Along part of its length, the river forms the boundary between Hampshire and Surrey, and then between Hampshire and Berkshire. It rises in Rowhill Nature Reserve, Aldershot Rowhill, an isolated remnant of the extensive heathland that once surrounded Farnborough and Aldershot. The remaining heathland is used by the British Army for training exercises. After 20 miles (32 km) the Blackwater is joined by the River Whitewater near Eversley. The river gives its name to the small town of Blackwater, Hampshire, upon the river near Camberley.
