May 31st – My attention had been drawn to comments online that the canal water level had dropped significantly in the last couple of days, so I investigated – measuring from the weir bar to the current level was 123mm. Nearly five inches of water lost since Sunday when the canal was in heavy overflow.

Considering the length of this canal, this is a huge amount of water gone.

Subsequent enquiries with the Canal and River Trust suggest that they were unaware the valves had been turned off at Chasewater by Staffordshire County Council (see here) but I’m unconvinced the water would drop so fast considering the conditions.

I’m wondering if a downstream lock sluice was accidentally left open, perhaps.

It is said the situation is being rectified by pumping water in from Bradley, so it’ll be one to keep an eye on I think. A mystery.
