This is actually a really cool graph. What it is showing is that the total water in storage now is far higher than it is in a typical year at the same calendar date, and that most of it is in the snow pack.

But that does not equal an end to the drought. The drought has been multiple years of below median total water storage, and it will take several consecutive years of gains like this to recover from the drought.

If Lake Meade fills up to normal capacity this summer I’ll eat my shoe keep an eye out for it

Nah this isn’t gonna “fill it up.” Not even close - these are high relative to the median, the total water deficit is much greater.
