This little eddy in a river has a huge appetite. What could make it so, I dunno, efficient?

I'd say that the flooded river meant water seeped into an underground cave, cavern or stream and as it got faster, opened it up so became gibber and bigger.

I'd like to see what it was like when the water level dropped.

It seems it is karst, so there are plenty of underground waterways and sinkholes leading to them.

A working drain!

That's a possibility. Some of the comments here are worth reading. "It looks quite dangerous. I'd stay away from it." etc.

It certainly isn't the same one.

The one in the US is now so large it is bigger than a football field
and is eating away the trees and ground and getting bigger ever day.

I think it is at least 1/2 mile wide in all directions.

It's the mini-black-hole in the core of the earth which was created last year by the LHC and dropped into Lake Geneva late one night, from a rowing boat by two engineers at CERN when they realised what they had done. The level of the lake dropped considerably last year but I assume the BH has now eaten its way to the centre of our planet and is consuming stuff (as scientists call it) there.

This brought to mind the Lake Peigneur disaster...

Caco: thanks for the link. Awesome demonstration of "when things go wrong ... " :ok:
