Today in "infrastructure isn't meant to do that" news from Normal Island, a canal has fallen down a hole.

My thanks to @zaty for informing me that someone did once, in fact, actually pull the plug out of a canal! https://mulberryhall.medium.com/odd-this-day-5b1cfd1fdb32

@afewbugs @zaty Every few years, the Pontcysyllte aqueduct carrying the Llangollen canal has its plug pulled out for maintenance purposes.
