Nice one, Brian, I was just winding up to do an explanation myself  
when your post arrived - much more concise than I would have managed.

To come back to your original point, AIUI, the weir crests are not  
much above the cill level between the two locks concerned, and in  
some cases, the side pond leaks well before the weir overflows, hence  
the anxiety to make sure that the lower lock starts filling first.

Trevor, there is a rhyme to help you remember the sequence:

Red before white
You'll be all right
White before red
You'll wish you were dead!

Some years ago, there were a pair of lockies on the flight, Mick and  
Crystal, who could make that last line literally true. Mick in  
particular could do a good impression of Windsor Davies playing an  
enraged CPO addressing a defaulter.

On the occasion seared into my memory, I had attempted to be helpful  
by drawing a red paddle in anticipation of it's being needed, and he  
wasn't pleased. We were in Streamline, our Ownerships boat at the  
time, and his final, immortal observation was

"You Ownerships people think you are something special, but you're  
just glorified hirers really."

Glorified hirers has remained our name for share boaters ever since.
