Sometimes it holds water, sometimes it doesn't - for long periods either way. But no one is quite sure where the water comes from or where it goes to. Bit of a mystery for geologists and hydrologists over the years.






As you can see, when I was there only a few small ponds to be seen.

Did you look in the Wikipedia article about this lake? Because it explains why there is so little water in the area now. Millions of years ago there was a gigantic lake in this area. But now there is a layer of sediment 250 meters thick. Any water that is beneath that layer can't come up. What little water you do sometimes see is more often left over from rainstorms.
