How long before California needs more rain?

Right now, we have a generous surplus, but how long before we need more rain?

As some may recall, we've had some pretty historic winter storms during this water year. These storms have set us up for a great start. Just look, so far as of today's date, we've picked up 14.42 inches of rainfall at Sacramento Executive Airport. This gives us a surplus of 6.31 inches of rainfall.
