Where's the Thames gone? These pictures were taken during the lowest of low tides at Twickenham/Eel Pie Island yesterday, the result of the annual November draw-off. Every year the weirs at Richmond Lock are lifted to allow the Port of London Authority to carry out essential maintenance works on the lock, weirs and sluices. The weir being lifted allows the river between Richmond Lock and Teddington Lock to drain naturally at low tide and this creates a short annual opportunity to access the lower shore.
