Sonning Lock is a lock and associated weir situated on the River Thames at the village of Sonning near Reading, Berkshire, England.[2] The first lock was built by the Thames Navigation Commission in 1773 and it has been rebuilt three times since then. There is a weir a little upstream at the top of the island where Sonning Backwater separates from the main course of the river.
