Lake disappears in Chile

This disappear is hard to explain.  One day a large lake is there for everyone to see.  The moment the same large lake has disappeared.  Can this lake disappearance be explained as an effect of Global Warming?  I think not, if anything the lake should be overflowing with runoff from the Glacier(s) that are melting as a result of the warming trend.  Global Warming SMEs, I need this explained to me.
