The Gridiron and Bower Ashton Part Two
03 Dec 2021
On my last wander, to Bower Ashton, I was intending to knock Blackmoors Lane off my list "to-do" list, but got a bit diverted. I also took a little look into the history of the Gridiron, once a cheaper alternative to dry dock that was nestled just south of North Entrance Lock.
Today I had to go to send a parcel off somewhere, so I decided on going to the North Street Post Office via Blackmoors Lane. I didn't have much intention of anything else, but as luck would have it I walked out both at low tide and also as some lockkeepers seemed to be having a bit of a training session, and one of the more senior people was (a) happy to answer a few random questions on the Gridiron and (b) actually knew a lot about it, as Gridiron maintenance had been one of his jobs, more than twenty years ago...
I've always wondered what this wheel is for. It's part of the Gridiron's cleaning system. Water is drawn from North Entrance Lock through a sluice channel and could be diverted one way and another across the surface of the gridiron. I wasn't clear from my conversation with the lockkeeper whether this would open the sluice channel or was the control used to divert the water first to the left of this central point of the gridiron, then to the right, but it's definitely part of the cleaning mechanism.
He said he also used to have to go down the ladder and hose it all down after sluicing it out, and that he found the whole process quite fun!
