Hindsight is a wonderful thing. But they could have cleaned and polished that spillway and brought it caked for its birthday but in that extreme circumstance it might still have failed.

In extreme circumstances I believe it could have always failed after say 20 years ,and with the little maintenance it has obviously received shows a lack of responsibility and knowledge IMO.

Built correctly and for the full purpose instead as I strongly believe a simple Cap to just stop soil being washed away then yes you are right, but it was not built to withstand a torrent of water it was built to simply stop soil being washed away for the very near future back then...It was a simple short term cap ...by not realising it would fail in time then they now have failed in their responsibility to carry out adequate risk assessment's. Climate change has been shoved down our necks for years , that post I did of the years with flooding shows it is a real possibility anywhere in the UK in any one year so to keep this Dam full is or should be a risk, no hindsight needed just common sense.

So maybe they should of repointed the slipway slab joints with some Non-shrink cementitious grout for underwater installation conforming to the requirements of BS EN 1504-3 Class R4?

Instead of having trees sprouting between slabs...

 

Also why does the slipway get narrower instead of wider or straight down  on the side it failed? Shouldn't it be the other way round?

Would aid in directing the water away i would guess 🤷‍♂️ i.e the overflow/slipways direction of course would run from right to left in the picture.

Nice question OSM was the spillway constructed at the same time as the reservoir was formed?

No, apparently the spillway was only concreted 50 year ago.

The slipway that failed was an add on, installed by 1969 after the original failed in 1964.
