Buck Ait

Buck Ait is an island in the River Thames in Oxfordshire, England.

It lies low, acting as a water-meadow in times of flood, opposite houses with large river frontages.

Its shape shows the cumulative effect of the locally curved stream, its erosion and deposition make the upstream end almost joined to the bank; the downstream end, broken into islets.

Late 19th century Thames Conservancy records state they caused considerable hindrance to navigation.

Eel bucks were set in St Patrick's Stream on the bank opposite upstream also; perhaps once a tributary of the mouth of the Loddon which became a distributary of a foreshortened Loddon when water levels rose by the building of Shiplake Lock and its heightened weir.
