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...
If you look at the lock wall, about halfway between the lock gates and the inset ladder, you'll see a little square hole. I had no idea what it was for until today, and I had no idea I was going to find out...
There were various people on the other side, I got the impression it was some kind of training session, perhaps. Later I'll have a quick chat with the man in the high-vis jacket over there.
In the meantime, I do always enjoy seeing the giant gridded lock gates uncovered by a low tide.
This used to be a view of the Gridiron, the structure I mentioned on yesterday's wander.
I got curious and went back to ask one of the lockkeepers about it. As it turned out, he knew lots about it as he'd previously been responsible for cleaning it! More about that when I come back (including a historical photo of a boat on the Gridiron for some context) as some of the things he told me needed me to retrace my steps for some more photos.
First, though, we'll nip over to Bower Ashton and North Streeet for a quick bit of shopping and to knock Blackmoors Lane of my "to do" list.
If you recall, before I left this area on the outbound leg of the wander, I had a chat with one of the more senior lockkeepers. He told me that the gridiron was definitely still there, and, look—there at the far left-hand side. What's that poking out of the silt?
Yes, having compared it with old photos and the 1946 aerial view I posted on Sunday I'm sure that that's the end of the gridiron, all 200 feet of which is apparently still there beneath the silt.
The lockkeeper told me that the gridiron was in use as recently as 2000, and that it used to be his job to wash the silt build-up away, using a sluicing system we'll get to in a moment.
I didn't realise I'd buggered up the focus on this shot until I got home and saw it on the big screen. They can't all be winners...
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!
This is about halfway along the Gridiron. You'd sluice water back and forth from this point to rinse the silt off the Gridiron as part of its regular maintenance. This was still being done until around the year 2000, when it apparently became more trouble/cost than it was worth for the dwindling number of boats using it.
Bower Ashton is an interesting little area just south of the river from me—in fact, the Rownham Ferry used to take people over from Hotwells to Bower Ashton, operating from at least the twelfth century to around the 1930s.
It's a strangely contradictory little area, with a cluster of old and new houses sandwiched in between the busy A-roads and significantly more industrial area of Ashton and the bucolic country estate of Ashton court roughly east to west, and also between Somerset and Bristol, north to south.
I've been around here before, mostly poking around Bower Ashton's arguably most well-known bit, the Arts faculty campus of the University of the West of England, but I'd missed at least Parklands Road and Blackmoors Lane, so I initially planned just to nip across briefly and wander down each in turn. On a whim, though, I texted my friends Sarah and Vik in case they were out and about, and ended up diverting to the Tobacco Factory Sunday market first, to grab a quick flat white with them, extending my journey a fair bit.
To start with, though, I nipped to a much more local destination, to see something that you can't actually see at all, the Gridiron...
(I also used this wander as a test of the cameras in my new phone. I finally upgraded after a few years, and the new one has extra, separate wide and telephoto lenses compared to the paltry single lens on my old phone. Gawd. I remember when speed-dial was the latest innovation in phones...)
You can't actually see the Gridiron in this photo, but I believe it's still there, under that amazing buildup of silt.
The Gridiron—one of the few photos of it can be seen on the Maritime Mud and Miasma page of About Bristol—was a cheaper alternative to putting your boat in a dry dock. It was a 200-foot long grid (there seems to be some debate over whether the grid itself is actually metal, or in fact timber; I'll have to try to find out), 38 feet wide, nestled here between the north and south entrance locks. A ship captain could sail his vessel over here at high tide, then as the tide gradually receded, the ship—up to 250 feet, as overhanging a bit was apparently okay—would settle onto the gridiron.
At that point an inspection and repair crew could make their way down to the gridiron by ladder and do whatever work they could manage before the tide rose up again.
You can still see some ladders in place, I can only presume they were there to get you down to the gridiron, but that is just a guess; information on it seems quite hard to find.

As you can see, it was pretty big, and clearly still in use in 1946...
One last snap before we move on. I'm using the wide lens on the iPhone here, and have managed to include a silhouette selfie...
