I don't think 96" of water is needed to grow potatoes.

I am thinking for potato production you would also have to be on a three year rotation. Therefore a large volume of the water pulled would be used for corn, soybean etc irrigation.

I am guessing there are other farms that pull irrigation water from the Edisto or other rivers in the state.
Beat me to it. 3yr rotation is correct.
