A watching brief was maintained by J Robertson of SCAU, for Mr. R Stilgoe, on an extension to an existing lake following an evaluation in 1997. The site lies on the projected line of the London-Lewes Roman road. As in the evaluation, remains of the road were not found on the predicted course, although evidence for a plough-damaged metalled surface 15m to the west was recorded. The quantity of finds recovered suggests occupation in the immediate vicinity in the Roman period. Good quality flintwork of Mesolithic or Neolithic date was also recovered, although no obvious features of these periods were seen.
