I just ran some quick numbers, in case anyone cares:
White oak runs about 47 lb/ft3 at 20% MC. MC is ratio of H20 mass to dry weight mass, so that 47 lb/ft3 works out to roughly 7.8 lb. of water + 39 lb of wood.
But when it arrives at the sawmill, it's usually 60 - 65 lb/ft3, meaning roughly 24 lb. of water for each cubic foot. That would put it's MC% a little over 60%.
When first felled, the MC% can be over 100%, particularly certain times of year. This just means that by weight, you're hauling more water than wood mass.
