No lessons will be learnt. Virtue signalling is more important than
actually achieving reliable infrastructure.

Hopefully the company that did the annual safety inspection and
pronounced the dam "absolutely fine" is well insured - because all
the work over the past week will have cost a lot.

It probably WAS absolutely fine until the heavy rain


Doubt it. From the photos of the concrete break up, the earth
underneath had been washed away for weeks beforehand.

I don‘t see how you can possibly infer that. It‘s *possible* but given
the speed with which fast moving water can erode riverbanks etc, it
seems equally likely that this was an ”acute• event.

If the water had been going over the slipway, then I'd agree with your
suggestion. But it wasn't.


It had been going over the spillway though.

It only needed the grouting to fail between the slabs for erosion of the
soil beneath to begin.

But, seeing how many sacks were delivered, the erosion under the slabs was
massive.
