Mud, Mud, Glorious Mud

Here's a sight that you don't see everyday. A canal closed due to 'roadworks'.

It's interesting how that have managed to block the section, make it watertight and pump all the water out.

I wonder what sort of things they found when all the water was removed? Old tyres, cones, and it you look carefully there's even a bicycle propped up against the wall. I wonder if they came across any guns or weapons as they were dredging? It's certainly an opportunity to unearth something unusual.
