Wish Stream is a small, steep English river, which is a tributary of the River Blackwater. Mostly it demarcates Berkshire and Surrey. It rises on heath land to the north of Camberley, and descends in a south-westerly direction, passing through the grounds of the Royal Military Academy Sandhurst. Two large lakes have been made before it leaves the grounds, to pass through a culvert under a retail park and bridges under major roads to discharge into the Blackwater.Ordnance Survey, 1:2500 map, 2020
