in Abingdon in 1052, the River Thames was the main transport route for goods between London and Oxford. There were complaints from people in both these towns that, where it passed the Abbey, the River Thames was so blocked up that river traffic was seriously hampered. In response Ordric ordered a new navigation channel to be excavated, possibly enlarging a previous less navigable one. The channel left the main stream near Thrupp, and passed through the meadows of Andersey to the south of the Abbey Church, flowing back into the Thames at Culham. This new channel remained the main navigation for over seven centuries. The toll per boat was a hundred herrings in Lent. Around 960 AD, the monks had built a head mill stream to the Abbey from the direction of the Swift Ditch. During Tudor times, the channel was known as ''Purden's Stream''. However by the end of the Tudor period it was known as Swift Ditch, remaining the faster route.
