What the ******! is going on?

 When we woke up this morning our boat was heeling over a bit, but not because the water level had dropped but because it had risen by a further 5 inches (my estimate) overnight! I had to go out and loosen off our ropes - not easy when they're stretched really tight.

Two days ago we were stepping UP from the boat to the pontoon, now we're stepping DOWN. Look-

We have to assume that CRT are letting more water down the lock flight for some good reason, but it's a puzzle. Huge stretches of canal are closing all over the land because of low water levels.  I wandered up to the canal entrance to the marina where we have had stop planks installed. Fat lot of good they have done, the water levels either side have been equal all the time.  Anyhow last week it was like this

see the metal Arnco rail a couple of inches above the water level on the far bank?  Well today it's under water

Stupidly I took this photo from the other side, but they're the same.

Looking at the far canal bank, I would say the water is a little above the normal 'good' level.

The canal is of course still closed to boating for a good number of miles around here and I'm sure this rise is very local.

It did rain for something like an hour this afternoon, but that can be nothing to do with it. I doubt if it was more than a milimetre's worth.

Hey ho. I was going to write 'Ours not to reason why', but I can't help reasoning why.

Toodle pip.
