Original message:

During last year we started to experience excessive leakage through the cill at Big lock 75 in Middlewich on the Trent & Mersey Canal which, by the end of the year was leading to problems with maintaining water levels.  We had been hoping to carry out repairs to this before Christmas but, unfortunately, this wasn’t possible. Our teams are now proposing to lower the canal level in this area on 5^th February with the expectation that work will be completed and the canal back open by 15^th February.

I couldn't believe how long that lock took to empty last August, I must have been there half an hour, made the mistake of closing the offside paddle when I thought it was almost empty, then watched the lock fill up again.

Fortunately there's quite a lot of traffic between the T&M south and the Middlewich branch. Each boat doing that route dumps two locks full of water down the bywashes of the Middlewich flight, which are frequently running very hard. That's normally enough to keep the pound above Big Lock full.

It was surprising how often the Middlewich flight was low in the week we spent in the drydock
