Around Cerkniško jezero

What does that mean? Well, the lake has periods of high and periods of low water. That is, it dries up (not completely) when there is no rain and fills up to the point of flooding some nearby villages in heavy rains.
How can that be? The lake resides on a limestone basis, which easily absorbs water through, among other things, sinkholes - like the one on the photograph. They sure look surreal to me ...
