Acres per Second: a 30-foot lift, on the suction side of a pump?? Sea level atmospheric pressure will push a column of water up only 33 feet into a complete vacuum. From that you have to subtract what little pressure you get from the lake's 504 feet elevation, plus the vapor pressure of the water at the lake temperature (less than a foot's worth).

Perhaps I don't understand your current situation regarding the house pump: does it actually pull water from the lake up 30 feet? If so, that's some good pump, I'd say.
