Thames Barriers -- keeping water out; and in at Richmond Lock and Weir

The Thames Barrier is an awesome structure built to avoid floods in London from extreme high tides.  Click the link  http://sussexrambler.blogspot.com/2009/02/eastenders.html for more pictures from Canary Wharf to the barrier.

Way upstream past central London at Richmond is a different barrier, built to keep water in the river; seen above from upstream.  These photo's taken yesterday.

The view of the lock from the bridge looking downstream as the tide is going out.

The impressive engineering to vertically lift the 32 tonnes steel sluice gates.

The view from downstream as the tide goes out.  The sluices are raised and any boats must use the lock at £5 a time.  What magnificent engineering built in 1894.  Click here for further information from the Port of London Authority (PLA) on Richmond Lock.  And click here for more PLA information on the Thames Barrier.
