Bridgewater canal bank collapse
Discussion
A lot of flooding around Lymm and Dunham Massey area has been caused by the collapse of the canal banking in the area, I drove back from Lymm and noticed the police helicopter in the air and several police cars racing to the area. I assumed it was the river Bollin .

Looks like the worst possible location straight into the adjacent sewage works!

A good comment: 'What this country needs is more civil servants working from home making plans for climate change, rather than doing practical things like dredging rivers and maintaining water ways. (Ps. This is sarcasm in case you read the Guardian).'
Canals don't hold much volume of water though, they're narrow and shallow and you'd only drain a pound (ie between locks) not the whole thing. Perhaps there was a river involved too.

Been watching a few videos on this as I know the area. Looks terrible and people on the boats it must be quite a thing being stuck and potentially not level.
I'd imagine the amount of rain over the last few weeks/months has put and incredible amount of weight into the sidings and forced the breach, I'm no expert but it looks like a major job to get this resolved and running again. No doubt having to dam either side and get the stuck boats out somehow before they can begin any excavation and repair work.

Hindsight is a wonderful thing but:
'this breach took place after 16 hours of non-stop heavy rain, that filled the canal up so much that it was going above the towpath and flooding over this put so much pressure on a 260-year-old canal embankment that it completely collapsed into the worst breach since 1971, when the canal breached here, in the exact same spot!'
Perhaps a weir or other kind of spillway could have relieved the pressure.
The stop boards were pretty rubbish!

Quite! There was always a bit of concern at Farnborough Airshow time that some terrorist group or other woud try and blow the bank on the Basingstoke Canal thus flooding the Laffan's Plain end of the airfield.
Whilst on the Chesterfield Canal, in 1978, an over-enthusiastic dredging crew pulled the plug out.
