Yes, the original Harvington Lock, part of the 1970s Upper Avon restoration, (now a drydock) was later replaced by

To quote The Story of the Rebuilding of the Upper Avon Navigation by John Grundy "Nine new locks were built, each unique to suit the donated gates available and the local ground conditions.  No attempt was made to restore what little remained of the original infrastructure.  Weirs and water levels had to be rethought...." So with the double-rebuilding at Harvington, that gives ten. The Lower Avon's locks were all reopened on their prewar locations. (iirc)

This is another double-replacement, with  Lock 3E-the-third opening in 2012. It is close-to but not exactly the same as Lock 3E-the-first. Summary of the tale is here

River Nene locks have all been completely rebuilt and I suspect in many cases relocated since 1930. Weston Favell is part of a 1970s flood defence scheme so I doubt it bears any resemblance to the original river navigation design. Dog in a doublet was brand new to extend the non-tidal section just outside your suggested timeslot in 1937 - think more for flood defence than commercial traffic.

There will have to be several on the Stroudwater very soon 😎 


As for locks that were when did the Nechells stop Lock disappear? The gates at Worcester bar went in the 1970s possibly earlier  but I don’t believe it was a true lock ever or not for a very very long time.

Several? Just a couple more like it 🙂

 

Still no bad thing though 😀

My date may be arbitrary but was chosen to EXCLUDE such things! Otherwise we end up with most of the Nene, the large locks on the Trent etc - I chose post war as being "The Leisure Era" with freight on the decline or vanished

Perhaps another way of looking at this is to define your list of new locks by the reason they were built, rather than some arbitrary date. The list includes those locks built either as part of a waterway reopening or necessitated by external causes such as a road or flood relief scheme (but not those locks built primarily to improve the carriage of freight by water).

That would exclude the 1930s GU widening, larger locks on the Trent, and the Sheffield and South Yorkshire modernisation, but include most of the others which have been mentioned.

As it happens I have a pic. of the old lock taken in April 2010 when we did the Leicester Ring.

 

Along with a view from below both locks. The old lock to the right being obscured by vegetation.

Took a chunk out of the top gate on latest incarnation when gear change cable broke as I reversed back to pick up my wife. Quiet place to spend the night despite the students.

The main works on the Nene date from the 1930s. But since then

 * Abington lock is new (part of the flood defence scheme on the Northampton washes, with flood gates just downstream of Abington and upstream of Weston Favell

* Lower Wellingborough looks relatively new (also rather badly designed). I would suspect also the other locks that have two sets of V doors, ie Upper Wellingborough, and Higham.

And Bottisham lock on the Cam has been rebuilt or relocated - my copy of Bradshaws is on the boat so I can't check. It may even (like Brandon) be part of the 1960s work when the relief and cutoff channels were built.

Scotts Float Sluice. Tidal entrance to the River Rother, in Sussex. New floodgates and double radial gate lock built 1984, downstream of original sluice.

So it's not true that Carpenters Road lock is unique ....

No, I did some research on this lock for the NB Ocean Princess Scilly Isles Cruise in 2003. They got permission from EA to come in on the level, but they carried on!

Fulney Lock, tidal lock on the River Welland, just downstream of Spalding. This lock was finished in 1955, along with the Coronation Flood Relief Channel. AFAIK the river was tidal through Spalding before this lock was built.

A lot of good stuff - in the next day or two I shall revise the list with most of the extras

 

On reflection, tidal barrages that create an inland non-tidal navigation count (at first I took the view they didn't), so Tees Barrage, Swansea, Cardiff etc - locks on tidal marinas don't, because these aren't an inland navigation, and also because I suspect there are a lot, probably not related in any way to inland navigation. Tidal river barrage locks are therefore an interesting subset. 

 

I think the Nene locks that have simply lost their guillotine gates were partly rebuilt rather than entirely new locks,but I do acknowledge that others were relocated. 

Hulme Lock was simply extra wall, rather like Anthony on the Rochdale, albeit with rather more extra wall! 

I had several reasons for not going back before WW2 - one of which was the large number built in the 1930s - these are worth a seperate section all to themselves. I'm primarily a historian, so time periods interest me, and I'm interested in this case in locks of the second half of the 20th Century and early 21st as that's a relatively homogeneous time period in waterway history.

Stranmillis on the River Lagan?

 

 

 

Thanks I I think Ireland needs a category all to itself - they do things different over there! Some of my Irish friends have noted this is the first new manual lock on the island of Ireland for many decades, other new ones have been mechanised, I haven't checked yet whether this is true, but it sounds plausible.

List for post war British Mainland to follow when I get round to it!

Middlewood deep lock on the Manchester, Bolton and Bury Canal replaced the original 2 locks in the 2000s.

Still not made your list, or have I made an error here, it is like Tuel Lane on the Rochdale if I recall correctly.
