This is an old photograph - the Surrey Space Centre now stands below the rooftop dish, where you see the prefabs, and a new three-storey extension to that housing CCSR, to the right, has just been completed. The dark spot in the centre at the lake's edge is the channel where water flows down from the higher duck pond.
If this small view has rippled successfully long enough for you, you may prefer to admire the large view.
Thanks to David Griffiths for creating the lake applet.
