The morning after

Thank you for all the kind comments yesterday, in the end the water stopped a couple of inches below critical.
Waking this morning the garden was visible again and the yard water free. The changes we've made in the garage (rubber matt flooring instead of carpet, raised sockets etc) meant that by mid afternoon it was mostly dry.
Chatting with the (nice/sane) neighbour we've both agreed a few things:
If the hall behind us won't maintain the waterway then we are going to build a flood barrier wall along our boundary. It will effectively create a holding tank in their grounds. The neighbour has also agreed we can render/tank the stone garage on his sides.
For us it was clear that the water pressure where the Beck goes through the culvert under our drive has forced fissures up through two foot of concrete, we had four little water spouts last night that looked like garden hoses on full flow - I'm sure they added a lot to the water near the house. So we'll need to ultrasound scan the concrete to locate them and get them drilled out and filled. I took lots of photos to show to the planners next week. It should help explain why I want to put the new garden office a foot off the ground!

Localised flooding meant I had to go into town via the A6 which was a fairly exciting drive with several sections of road damaged. This is Borrow Beck which I've blipped before. Normally you could walk across it here at its widest point and barely get the soles of your boots wet. Wouldn't fancy it today. For sheer scale the landslip was carved out in the 2015 flooding when the river was 6ft higher and the green to the right was an oxbow lake!
