Monument record MBC48597 - Post medieval drainage ditch system, River Thame, Whaddon Hill Farm

A post medieval drainage ditch system is visible on historic aerial photographs and remote sensing data as earthworks and was mapped as part of the Aylesbury Vale Aerial Investigation and Mapping project (EBC18604). Located on the south bank of the River Thame about 930 metres NW of Whaddon Hill Farm and centred at SP 78329 13959, a system of interconnected parallel and perpendicular linear ditches up to 1.5 metres wide extend across the meadows adjacent the river about 250 metres N-S and 160 metres W-E. At two points the ditches connect with the river as tail drains. On aerial photographs taken in 2023 and recent remote sensing data, the featured ditches appear to have been levelled (1-3).
