Not to argue, but the article does say this isn't the first time the lake has disappeared. Wikipedia also adds that "The time period between 1975 and 1992 is the longest period in recent times with a continuous existence of a water body."
edit: the article's title is actually, "Proba-V eyes Bolivia’s vanishing lake" which is actually decent in that it seems to be trying to describe that the lake "vanishes" from time-to-time and that Proba-V is showing some views of it.
