In October 2013 Oxford Archaeology conducted an archaeological test-pit evaluation and watching brief during the excavation of a channel diversion at Farnham Bourne, Surrey (centred at NGR: SU 8472 4617). The excavation exposed modern reinforcement of the south bank of the water course together with two phases of probable garden soils overlying alluvial deposits. The existing channel’s location, above the level of the gardens to the south, suggests that the water course was channelised, probably to supply a mill further to the east. No evidence for activity pre-dating the 19th century or for any earlier channels was encountered
