How much water is in a cloud

It’s definetly autum here in Holland. The whole country has been under a thick pack of clouds for a couple of days on end now. Which made me wonder: how much water is up there anyway? Let’s pick a sample of one square mile of this thick pack. If it was condensed, could you fill a swimming pool with it or just your bathtub?
