What is the effect of the full annual closure on the tide levels at and below Teddington, Howard?

So, if I understand correctly, the answer would appear to be that Richmond Barrier remained closed because of what was happening at the Thames Barrier.

Sorry, I hadn't appreciated that you were referring to the Richmond half tide barrier - thought you meant THE barrier ! /forums/images/graemlins/grin.gif
Maybe Ted Lock can give us the lowdown later?

It means that we see no rise of the tide at all at Teddington for the time of the Barrier closure , because no tide comes in , the Richmond barrier is not lifted.
The Richmond barrier is lifted when the level below the barrier reaches the level above the barrier , then the river becomes tidal to Teddington.
When the tide is falling , when it has fallen to the height of the Richmond barrier , they put the barrier down , holding a maintained level between Richmond and Teddington , while to tide continues to fall below Richmond.
When the draw off takes place , we become fully tidal for a while as the maintainde level is allowed to fall with the tide to give access to the river bed and underwater structures.
Typically we lose 5 or 6 feet extra off our normal 'low tide' level at Teddington during the draw off.

And take pity on the poor pensioner who, due to the predicted tides, will have to stay up in Teddington for nearly 6 weeks before, during and after the draw-off.
But then again, you will have to listen to his winging for all that time while he is there and in the Tide End after 4pm. /forums/images/graemlins/grin.gif

It's a concrete, Alan Buchanan sloop(?) owned by Jimmy Tuttle.
He is going to get his new mast craned on while he is up there, so we'll have to think of some prank to play on him. /forums/images/graemlins/smile.gif
